We need answer user asks: "If i wanted to remove shaders effect/magic visual effects from player in skyrim. Make it into dll plugin, how would the logic will be?" We need provide explanation how to make SKSE DLL plugin to remove shader effects/magic visual effects from player in Skyrim. Need infer Skyrim Classic or SSE? Likely Skyrim Special Edition/Anniversary. Need discuss logic: detect player character, find magic effect shaders / visuals, remove/disable them. Need maybe mention approach using SKSE, Address Library, CommonLibSSE-NG. Need be practical. We need answer with logic steps, code snippets perhaps. Need cover: - Understanding magic visual effects are "MagicShader" / "Shader" effects? In Skyrim, magic visual effects on player often are "MagicEffect" with "Hit Shader" or "Enchant Shader"? There are "EffectShader" objects applied via "PlayEffectShader" or attached to active magic effects (MagicItem). - Active Magic Effects: Player has MagicTarget, effect list (ActiveEffects). Each ActiveEffect has MagicItem, effect setting, and maybe visuals. To remove just visual, could stop the effect's shader? But may be attached to effect (like flames, frost, lightning, etc.) There are also "hit shaders" (e.g., on fire) that are applied as temporary visual effect, often via Actor::ApplyHitShader? - There is "MagicTarget::DispelAllSpells" but that removes actual effects. User wants only visual effects, not gameplay effects. So need target shader effects only. - There is class "EffectShader" and "ShaderReference" or "TESEffectShader". They have functions to play/stop. Need find active shaders on actor. Maybe via "Actor::GetActiveEffectShaders" or "MagicTarget" some list? We need know internals. We should propose reverse engineering with CommonLibSSE. Possibly existing mods: "No More Glowing Edges", "Remove All Ugly Spell Effects", "No More Glowing Weapons" etc. Use hooks. Need outline logic: 1. Identify when an effect shader is applied to player. Could hook functions that play effect shaders: - EffectShader::Play (or BSEffectShader::Play) virtual - Actor::ApplyHitShader (or MagicTarget::ApplyHitShader) - Maybe Effects: Actor::AddSpell, etc. 2. In hook, if target is player and shader meets criteria (e.g., magic visual, not armor/weapon?), skip or stop immediately. 3. Or periodically scan active effects and remove shader entries. Need be more specific about game structures. Let's recall Skyrim SKSE plugin modding: CommonLibSSE-NG provides classes: - RE::PlayerCharacter::GetSingleton() - RE::Actor, RE::MagicTarget, RE::ActiveEffect, RE::Effect, RE::EffectSetting, RE::TESEffectShader. - RE::MagicTarget* magicTarget = actor->GetMagicTarget(); or actor->AsMagicTarget(); - MagicTarget has activeEffects list: RE::BSTArray? Actually ActiveEffects stored in MagicTarget::activeEffects (maybe a vector of ActiveEffect*). - ActiveEffect has effectSetting (RE::EffectSetting*), magnitude, duration, flags, etc. It also has visual effect flags? - EffectSetting has "hitShader" or "effectShader" data? In Skyrim, magic effect has "Hit Effect Art" (BSEffectShader) and "Enchant Art" maybe. The EffectSetting has fields: - data.hitShader (TESEffectShader*) - data.enchantShader (TESEffectShader*)? Not sure. - The visual shader playing is likely handled by ActiveEffect or MagicTarget? The actual application of shader is done by ActiveEffect::Start or by magic item visuals? There is class "BSEffectShader" with "Play" and "Stop". It may be referenced by "MagicCaster" or "ActiveEffect". - There is also "ShaderReference" in ActiveEffect? Need know. Alternatively, can simply call actor->GetMagicTarget()->DispelAllSpells()? But removes effects. Better approach: Hooking the effect shader play functions. Need decide hook targets: - RE::BSEffectShader::Play (or RE::TESEffectShader::Play). Signature: void Play(RE::TESObjectREFR* ref, float duration) maybe? In CommonLib: RE::TESEffectShader has `BSEffectShader`? Let's recall classes from CommonLibSSE. CommonLibSSE has `RE::EffectShader`? Let's search memory: There is `RE::BSEffectShader`? Actually game uses `BSEffectShader` for visual effect shaders? And `TESEffectShader` is a form that contains BSEffectShader data. In CommonLibSSE-NG, there is `RE::TESEffectShader` and `RE::BSEffectShader`. The `TESEffectShader` has `Play(RE::NiAVObject* object, float duration)`? Hmm. Let's recall from SKSE plugin examples: - The "EffectShader" class is `RE::TESEffectShader`? It has functions: - `void Play(RE::NiAVObject* object, float duration = -1.0f, RE::TESObjectREFR* target = nullptr);` - `void Stop(RE::NiAVObject* object);` - maybe `void Play(RE::TESObjectREFR* ref, float duration)`? - There is also `RE::BSEffectShader` which is a shader object, but not directly used by forms. Better to look at existing mods. For example "No More Glowing Edges" by doodlum? It hooks `EffectShader::Play`? I recall a mod "ShaderTools" maybe. Need produce plausible code using CommonLibSSE-NG. Let's outline possible hook: ```cpp class EffectShaderHook { public: static void Install() { REL::Relocation vtable(RE::VTABLE_TESEffectShader[0]); _originalPlay = vtable.write_vfunc(0x??, Play); } static void Play(RE::TESEffectShader* a_this, RE::TESObjectREFR* a_target, float a_duration) { if (a_target && a_target->IsPlayerRef()) { return; // skip shader } return _originalPlay(a_this, a_target, a_duration); } }; ``` But need know vtable index. Alternatively hook `RE::BSEffectShader::Play` maybe simpler. Another approach: Hook `RE::MagicTarget::ApplyHitShader` or `RE::Actor::ApplyHitShader`. Need provide more concrete. Let's search memory: In Skyrim SE, the function that applies hit shaders to actors is `void MagicTarget::ApplyHitShader(TESEffectShader* shader, float duration)` maybe. It is at vtable? Let's recall from Address Library IDs? Not sure. CommonLibSSE provides `RE::MagicTarget` class with: - `void ApplyHitShader(RE::TESEffectShader* a_shader, float a_duration);`? - `void RemoveHitShader(RE::TESEffectShader* a_shader);`? MagicTarget has `activeEffects` and `hitShaders` maybe. I can propose using `MagicTarget::ApplyHitShader` hook. There is such method in actor's magic target? Actually in Skyrim, when you are hit by fire spell, there is "hit shader" applied. That's a visual shader on the body. So magic visual effects can be via hit shaders. Alternatively, "Effect shaders" are for continuous effects like flames on body, ice, etc. These may be applied through `ActiveEffect` and played on the actor's root node. The ActiveEffect may call `EffectShader::Play` on the target's NiNode. So hooking `TESEffectShader::Play` should catch both. Need maybe include both hooking EffectShader Play and MagicTarget ApplyHitShader. Now we need provide answer as "logic will be". Probably user asks for conceptual logic, maybe not exact code. We can describe steps. Need mention removing existing effects: - When loading game or after player becomes affected, scan active effects and remove their shaders. Could maybe call `a_effect->SetEffectShaderLifetime(0)`? Hmm. Better to propose two parts: 1. Prevent new shader visual effects from appearing on player: Hook the play/apply functions. 2. Cleanup existing visual effects: Iterate through player's active effects, and for each effect setting (or hit shader), stop shader on player. Or hook and skip, but existing effects already applied need removal. Need include mechanics for identifying shaders that are "magic visual effects". Could filter by shader's name or editor ID? Or simply all effect shaders excluding maybe those from abilities/perks? Magic visual effects include: - Hit shaders (fire, frost, shock, absorb, etc.) - Enchantment shaders (glowing weapon/armor? maybe on player) - Magic effect shaders (e.g., flames on body) We can decide to remove all effect shaders from player, not just magic, but user says "shaders effect/magic visual effects from player". So likely all effect shaders on player are magic visuals. So skip all. Need maybe include note about not removing "glow" from enchantments? But that is also visual effect. Could be desired. Now let's think of actual implementation details. Potential method via commonlib: - Hook `RE::TESEffectShader::Play`: - Need find vtable address. We can use `REL::Relocation vtable(RE::Offset::TESEffectShader::Vtbl);` But offsets not known. CommonLibSSE-NG has `RE::VTABLE::TESEffectShader[0]`? I think there's `RE::VTABLE_TESEffectShader` maybe defines in `RE/Offsets.h`? Actually CommonLibSSE-NG provides `RE::VTABLE::TESEffectShader` in `RE/Offsets.h`? Could be `RE::VTABLE_TESEffectShader[0]`. - In CommonLibSSE-NG, there is `REL::Relocation vtable(RE::VTABLE_TESEffectShader[0]);`? I know they have `RE::VTABLE` struct with static constexpr std::uintptr_t TESEffectShader = ...? Maybe not. - CommonLib has `RE::C_TESEffectShader`? Not sure. Alternative: Use `SKSE::GetTrampoline()` with address from Address Library using ID. We can use Address Library IDs for `TESEffectShader::Play`? Need know IDs. Could use signature scanning? Better to avoid exact offsets. We can show pseudo-code with placeholders using `REL::VTable` or address library. Maybe we can describe logic without exact code, focusing on steps. But user asks "how would the logic will be?" They likely want a conceptual design. We can provide code skeleton. Let's produce answer with: - Introduction: use SKSE DLL with CommonLibSSE-NG. - Logic overview: 1. Hook the functions that add visual shaders to actors. 2. Check if target is player. 3. If true, bypass or immediately stop shader. 4. Cleanup existing shaders when plugin loads or when effect is applied. - Detailed steps: - Identify targets: `TESEffectShader::Play` (for effect art), `MagicTarget::ApplyHitShader` (for hit visuals), maybe `BSEffectShader::Play`. - Hooking: - Use trampoline to intercept virtual functions. - In hook, if actor is player, skip call. - Existing effects: - On plugin load or periodically, call `actor->GetMagicTarget()->GetActiveEffects()` and for each `ActiveEffect`: - Get `EffectSetting`'s `hitShader` / `enchantShader` and call `Stop` on player. - Or iterate `actor`'s geometry and remove shaders? - There might be a list of active effect shaders on `TESObjectREFR` or `MagicTarget`: `RefrAttachEffectShader` maybe. I recall `TESObjectREFR` has `BSTArray` or `RefrAttachEffectShaders`? - Code skeleton. Need be careful not to provide wrong APIs. Let's try recall actual CommonLibSSE APIs. I know from writing SKSE plugins: - `RE::PlayerCharacter::GetSingleton()` returns `RE::PlayerCharacter*`. - `actor->AsMagicTarget()` or `actor->GetMagicTarget()`? In CommonLibSSE, `RE::Actor` inherits from `RE::TESObjectREFR` and `RE::MagicTarget`? Actually `RE::Actor` has `RE::MagicTarget* magicTarget`? Let's check memory: `RE::Actor` has a member `RE::MagicTargetData* magicTarget`? Not sure. - `RE::MagicTarget` class is inherited by `RE::Actor`? Actually I recall `RE::Actor` inherits `RE::TESObjectREFR` and `RE::MagicTarget`? No, `MagicTarget` is a class that can be attached to any `TESObjectREFR` via `RE::MagicTarget::GetMagicTarget(RE::TESObjectREFR*)` maybe. - There is `RE::MagicTarget` as a class with methods like `DispelAllSpells()`, `GetActiveEffectCount()`, `GetActiveEffect(int)`. In CommonLib, `RE::TESObjectREFR` has a `GetMagicTarget()` method returning `RE::MagicTarget*`? I think yes: `RE::MagicTarget* magicTarget = ref->GetMagicTarget();` - `RE::MagicTarget` has `RE::BSTArray* GetActiveEffects();` maybe not. Let's look at CommonLibSSE-NG headers from memory: `RE::Actor` inherits from `RE::TESObjectREFR`, `RE::MagicTarget`? Actually in `RE/ Actor.h` maybe: ```cpp class Actor : public TESObjectREFR, public MagicTarget, ... ``` Hmm I recall `class Actor : public TESObjectREFR, public MagicTarget`? No, `MagicTarget` is not inherited; it's a component maybe. Wait `MagicTarget` is a class that represents the magic effects on a reference. It is actually a `BSScript::Object`? Hmm. Let's recall code examples: ```cpp auto magicTarget = actor->GetMagicTarget(); if (magicTarget) { for (auto effect : magicTarget->GetActiveEffectList()) { ... } } ``` I've seen `actor->AsMagicTarget()` maybe. In CommonLibSSE, `TESObjectREFR` has: ```cpp MagicTarget* GetMagicTarget() const; ``` and `Actor` has overridden maybe. Maybe `RE::MagicTarget` is not an inheritable class but a member of `TESObjectREFR` as `magicTarget`? I remember `RE::TESObjectREFR` has a member `RE::MagicTargetData* magicTargetData`? Not confident. Given uncertainty, we can write pseudo-code using comments like "// Use your version's API for active effects". But user likely expects actual design. We can focus on hooking function for preventing, which is simpler. Need maybe mention that there is a known function `BSEffectShader::Play` at `0x1406A4B70`? But not. I can structure answer as high-level logic with placeholder APIs and note to adapt to CommonLibSSE. Let's include code snippets but mark as illustrative. Potential code skeleton: ```cpp // CommonLibSSE-NG namespace RE { class TESEffectShader; class Actor; } class ShaderRemover { public: static void Install() { // Hook TESEffectShader::Play (vtable index 0x??) REL::Relocation vtable(RE::VTABLE_TESEffectShader[0]); _originalPlay = vtable.write_vfunc(0x??, &Play); // Hook MagicTarget::ApplyHitShader if available } private: static void Play(RE::TESEffectShader* shader, RE::TESObjectREFR* target, float duration) { if (target && target->IsPlayerRef()) { return; // skip playing shader on player } _originalPlay(shader, target, duration); } static inline REL::Relocation _originalPlay; }; ``` But need actual function signature. Let's search memory of `TESEffectShader::Play` in CommonLib: I think `RE::TESEffectShader` has: ```cpp void Play(RE::NiAVObject* a_object, float a_duration = -1.0f, RE::TESObjectREFR* a_target = nullptr); ``` Maybe not. Look at `EffectShader` class in SKSE? There is `BSEffectShader` and `TESEffectShader`. In game, `TESEffectShader` is a form that references a `BSEffectShader`. The `TESEffectShader` has `Play` method that takes `TESObjectREFR* target`, `float duration`? Or `NiAVObject* object`? Let's think of a typical magic effect: The effect setting has a `hit shader` (TESEffectShader). When spell hits actor, the game calls something like `actor->ApplyHitShader(effectShader, duration)`. The `ApplyHitShader` probably calls `TESEffectShader::Play(actor->Get3D(), duration)`? So signature may be `void TESEffectShader::Play(NiAVObject* obj, float duration)`. But we can attach hook at `Actor::ApplyHitShader` instead; signature likely `void Actor::ApplyHitShader(TESEffectShader* shader, float duration)`. Which one is better? Hooking `Actor::ApplyHitShader` will catch hit shaders only, not ongoing effect shaders. But effect shaders that play on body from active magic effects may be separate: they are applied via `MagicTarget::AddEffect` maybe and call `EffectShader::Play` on root node. Could hook `TESEffectShader::Play` to catch all uses. Need know signature. Let's try to recall from reverse engineering: There is class `TESEffectShader` with virtual function `void Play(NiAVObject* obj, float duration)` at vtable index 0x? Actually `TESEffectShader` inherits `TESForm` so vtable first entries are from TESForm: destructor, etc. The Play function might not be virtual? It might be a member function not virtual. Alternatively, the shader playing is done by `BSEffectShader` which is a non-form class. `TESEffectShader` has a member `BSEffectShader* shader`. The `TESEffectShader::Play` function might call `shader->Play(node, duration)`. Need maybe hook `BSEffectShader::Play` which is virtual? Let's recall: `BSEffectShader` has vtable? It is a `NiShader`? Could be. Better to refer to known mods. I recall mod "No More Glowing Edges" hooks `BSEffectShader::Play`? Actually in Skyrim, glowing edges on actors are from "ImageSpaceModifier" or "EffectShader" that are applied via `TESEffectShader::Play`. Mod authors often hook `EffectShader::Play` via SKSE. I can provide general logic without exact function signature, using "pseudo-hook" description. Maybe answer: - Use SKSE DLL and CommonLibSSE. - Hooking `RE::TESEffectShader::Play` (or `RE::BSEffectShader::Play`) to intercept all shader play calls. - In hook: `if (target && target->IsPlayerRef()) return;` - To remove existing visuals: on plugin load and after every cell load, iterate player's active magic effects and remove any effect shaders from the player's 3D node, or use `MagicTarget::RemoveHitShader` if available. - Provide code skeleton with `REL::VTable` and comments. Need maybe mention that `IsPlayerRef()` is a method on `TESObjectREFR` in CommonLib. Let's include a more concrete snippet: ```cpp // Hooks TESEffectShader::Play // CommonLibSSE-NG #include "RE/Skyrim.h" namespace { using Play_t = void(RE::TESEffectShader::*)(RE::TESObjectREFR*, float); Play_t originalPlay; void HookedPlay(RE::TESEffectShader* a_shader, RE::TESObjectREFR* a_target, float a_duration) { if (a_target && a_target->IsPlayerRef()) { return; // suppress visual effect on player } originalPlay(a_shader, a_target, a_duration); } void InstallHook() { // Find vtable index for Play in TESEffectShader (e.g. index 0x??) REL::Relocation vtable(RE::VTABLE_TESEffectShader[0]); originalPlay = vtable.write_vfunc(0x??, &HookedPlay); } } ``` But that's not compilable because need exact. Maybe better to describe using `SKSE::GetTrampoline()` and address library IDs. Example: ```cpp // Get address of TESEffectShader::Play from Address Library auto playAddr = reinterpret_cast(AddressLibrary::GetByID(12345)); originalPlay = *playAddr; *playAddr = HookedPlay; ``` But we don't know IDs. We can state: "Use Address Library to find the function, or use CommonLibSSE-NG's vtable helpers." That's acceptable. Need maybe also mention that there is an alternative approach: Hook `Actor::AddSpell` or `MagicTarget::AddEffect` to filter out visual effects before they are applied. But that may break spells entirely. Also could mention "Shader flags" on active effects: Some active effects have flags like "No Hit Shader", but modifying them is hard. Maybe include a simple "logic flow" diagram: 1. On plugin load, install hooks. 2. When game calls `PlayEffectShader` for any shader: - Check target. - If target is player, return immediately (no shader). 3. For existing effects (e.g., player already has fire cloak active): - On startup and when player loads game, scan `PlayerCharacter`'s `MagicTarget` active effects. - For each `ActiveEffect`, find its associated `EffectShader` or hit shader. - Call `Stop` on the player's 3D root. - Or clear the hit shader list on the actor. Need maybe mention that some magic visual effects are not effect shaders but "Image Space Modifiers" or "Attach Light" or "Art Objects". But shaders are the main. Potential additional detail: Need to ensure that the shader effect is not from a weapon enchantment or armor, but user says "from player" meaning on player's body, so all shaders on player can be removed. If they want only magic visual effects, perhaps filter by shader name (e.g., "Fire", "Frost", "Shock") but that's overkill. Now, about cleaning existing effects: There is a known function `Actor::ClearHitShader()` or `MagicTarget::ClearAllHitShaders()`? In game, `Actor` has `hitShader` array. Could call `actor->RemoveAllHitShaders()` maybe. CommonLib might expose `RE::Actor::ClearHitShaders()`? Not sure. I can mention that there is `RE::MagicTarget::RemoveHitShader` and `RE::TESEffectShader::Stop` can be used. Let's try to recall actual CommonLibSSE `MagicTarget` API from memory of code: ```cpp class MagicTarget { public: void DispelAllSpells(); void DispelEffects(RE::MagicItem* a_spell, RE::EffectSetting* a_effect); RE::BSTArray activeEffects; RE::BSTArray effectShaders; // maybe }; ``` Hmm. I've seen code: ```cpp auto target = actor->GetMagicTarget(); for (auto& activeEffect : target->activeEffects) { auto effectSetting = activeEffect->effectSetting; if (effectSetting) { auto hitShader = effectSetting->hitShader; if (hitShader) { actor->RemoveHitShader(hitShader); } } } ``` Something like that. Could include this as illustrative. Need maybe mention that the "player" is `RE::PlayerCharacter::GetSingleton()` which is an `RE::Actor*` and `RE::TESObjectREFR*`. Now let's produce final answer. It should be structured, clear, not too verbose but enough. Use headings. Possible answer outline: - Introduction: SKSE plugin, CommonLibSSE-NG, hooking. - Core logic: 1. Hook the function that plays effect shaders on actors. 2. In hook, if target == player, skip. 3. Clean up existing shaders on load. - Detailed explanation: - **Which functions to hook**: - `RE::TESEffectShader::Play` (or `BSEffectShader::Play`) – handles continuous effect art and hit shaders. - `RE::MagicTarget::ApplyHitShader` – handles temporary hit visual effects (fire, frost, shock). - **Prevention**: - Pseudocode. - **Cleanup**: - Iterate active effects and call stop. - **Considerations**: - Need Address Library/offsets. - Ensure not to break gameplay effects; only visual shaders. - Compatibility with other mods. Let's write in a helpful tone. Need include code snippets as "illustrative, adapt to your CommonLib version". Let's draft: ```cpp // Pseudo-code with CommonLibSSE-NG void InstallHooks() { // 1. Hook TESEffectShader::Play (vtable or address library) // e.g. REL::Relocation vtable(RE::VTABLE_TESEffectShader[0]); // _originalPlay = vtable.write_vfunc(Play_vtbl_index, &OnPlay); } void OnPlay(RE::TESEffectShader* shader, RE::TESObjectREFR* target, float duration) { if (target && target->IsPlayerRef()) return; // do not play shader on player _originalPlay(shader, target, duration); } ``` Maybe also hook `ApplyHitShader`: ```cpp void OnApplyHitShader(RE::MagicTarget* target, RE::TESEffectShader* shader, float duration) { if (target && target->GetTarget() && target->GetTarget()->IsPlayerRef()) return; _originalApplyHitShader(target, shader, duration); } ``` But not sure signature. For cleanup: ```cpp void RemoveExistingVisuals(RE::PlayerCharacter* player) { if (auto magicTarget = player->GetMagicTarget()) { // Remove hit shaders if (auto hitShaders = magicTarget->GetHitShaderList()) { // illustrative for (auto& shader : *hitShaders) { shader->Stop(player); } hitShaders->clear(); } // Iterate active effects and stop their shaders for (auto* activeEffect : magicTarget->GetActiveEffects()) { if (auto* effectSetting = activeEffect->GetEffectSetting()) { if (auto* hitShader = effectSetting->GetHitShader()) { hitShader->Stop(player); } if (auto* enchantShader = effectSetting->GetEnchantShader()) { enchantShader->Stop(player); } } } } } ``` Need mention that exact method names vary; these are illustrative. Could also mention that `TESEffectShader::Stop` might be needed to remove existing shader from node. We should also include note about "not all visuals are shaders; some are Image Space Modifiers, lights, or art objects. This method only removes shader effects." Now, let's think if there is a known function `RE::BSEffectShader::Stop` or `RE::TESEffectShader::Stop` signature. We can avoid exact. Let's include "Optional: Use task to run cleanup after load screens via `SKSE::GetTaskInterface()->AddTask` or `PlayerCharacter::GetSingleton()->AddAnimationEvent`". Now, final answer should be concise but detailed. Let's write. Important: User asked "Make it into dll plugin, how would the logic will be?" We should explain logic as a programmer. We'll answer with step-by-step and code skeleton. We can also mention "If you want to remove magic visual effects only from player, not from NPCs, filter by `IsPlayerRef()`." Need maybe mention "Some shaders are applied through `BSEffectShader::Play` not `TESEffectShader::Play`; track both." Ok compose final. But before final, let's consider if there's a simpler method: Hook `TESObjectREFR::AddEffectShader` maybe. I recall that code in game might have a list `BSTArray effectShaders` on `TESObjectREFR`. The `TESObjectREFR` has functions: - `void AddEffectShader(TESEffectShader* shader)` - `void RemoveEffectShader(TESEffectShader* shader)` These might be virtual? Hmm. Actually, from reverse engineering, `TESObjectREFR` has a class member `BSTArray effectShaderList;` and functions: - `void TESObjectREFR::AddEffectShader(TESEffectShader* a_shader)` - `void TESObjectREFR::RemoveEffectShader(TESEffectShader* a_shader)` The function `TESEffectShader::Play` might call `target->AddEffectShader(this)` after playing. So hooking `TESObjectREFR::AddEffectShader` could be cleaner: If target is player, skip adding shader to its list and also don't play. But we need to stop already played shader, so hook `TESEffectShader::Play` or `BSEffectShader::Play`. Maybe mention both possible hooks: - `TESObjectREFR::AddEffectShader` (or `TESEffectShader::Play`) - `MagicTarget::ApplyHitShader` That's good. Now final answer. Let's ensure no misleading exact function names. We'll label as pseudo-code. We might include "Get the vtable address via CommonLibSSE-NG's `REL::Relocation` and `write_vfunc`, or use Address Library with `SKSE::GetTrampoline()`." Ok. Write final answer with headings and code blocks. Here’s how you would design an SKSE DLL plugin to remove magic/visual shader effects from the player in Skyrim SE/AE. ## Core idea Magic visual effects on an actor are usually applied as **effect shaders** (`TESEffectShader` / `BSEffectShader`) or **hit shaders** (fire, frost, shock, absorb, etc.). The game calls internal functions to play/attach these shaders to the actor’s 3D node. To remove them only from the player, you need to: 1. **Hook** the functions that play/apply effect shaders. 2. **Skip** the call if the target is the player. 3. **Clean up** already-existing shaders on the player when the plugin loads or after load screens. --- ## 1. Hooking shader application ### Which functions to hook Look for these in CommonLibSSE‑NG or with Address Library: - `TESEffectShader::Play` – plays persistent effect art on an object/actor. - `MagicTarget::ApplyHitShader` – applies temporary hit visuals like fire/frost/shock to an actor. - `TESObjectREFR::AddEffectShader` – adds a shader to an object’s active shader list. The exact name/signature varies by library version, but the logic is identical. ### Example pseudocode with CommonLibSSE‑NG ```cpp // Hooks TESEffectShader::Play (vtable index must be known for your version) void InstallShaderHooks() { REL::Relocation vtable(RE::VTABLE_TESEffectShader[0]); // e.g. index 0x?? is Play originalPlay = vtable.write_vfunc(PlayVIndex, &HookedPlay); } void HookedPlay(RE::TESEffectShader* shader, RE::TESObjectREFR* target, float duration) { // If the target is the player, suppress the visual shader if (target && target->IsPlayerRef()) return; // Otherwise call the original function originalPlay(shader, target, duration); } ``` If you also hook `MagicTarget::ApplyHitShader`: ```cpp void HookedApplyHitShader(RE::MagicTarget* target, RE::TESEffectShader* shader, float duration) { if (target && target->GetTargetReference() && target->GetTargetReference()->IsPlayerRef()) return; originalApplyHitShader(target, shader, duration); } ``` --- ## 2. Removing existing shaders from the player Hooking only prevents **new** shaders from appearing. But if the player already has active magic effects or hit shaders when you load a save, you need to strip those visuals once. ### Pseudocode for cleanup ```cpp void RemoveExistingShaderVisuals(RE::PlayerCharacter* player) { if (!player) return; // 1. Remove hit shaders from MagicTarget if (auto magicTarget = player->GetMagicTarget()) { // Illustrative – actual API may be GetHitShaders(), RemoveHitShader(), etc. if (auto hitShaders = magicTarget->GetHitShaderList()) { for (auto* shader : *hitShaders) { shader->Stop(player); } hitShaders->clear(); } // 2. Iterate active effects and stop their associated shaders for (auto* activeEffect : magicTarget->GetActiveEffects()) { if (!activeEffect) continue; auto* effectSetting = activeEffect->GetEffectSetting(); if (!effectSetting) continue; // Stop hit shader from the effect setting if (auto* hitShader = effectSetting->GetHitShader()) { hitShader->Stop(player); } // Stop enchantment/effect art shader as well if (auto* enchantShader = effectSetting->GetEnchantShader()) { enchantShader->Stop(player); } } } // 3. Clear any shaders attached directly to the player's 3D node if (auto* root = player->Get3D()) { // You may need to traverse NiAVObject children and remove shader properties // This is more advanced and usually not necessary if steps 1-2 work. } } ``` Call this function: - When the plugin loads (if player is already present). - After every game load (`SKSE::GetTaskInterface()->AddTask` or via a message handler for `SKSE::MessagingInterface::kPostLoadGame`). --- ## 3. Important notes ### Does this affect gameplay effects? No, you are only intercepting the **visual shader** functions. The actual magic effect (damage, buffs, etc.) is still applied normally. Only the visual shader on the body is suppressed. ### Not everything is a shader Some magic visuals are not effect shaders: - Image space modifiers - Attached lights - Art objects / projectiles Those require separate hooks if you want to remove them. The method above covers the most common “glowing/fire/frost/shock” body effects. ### Compatibility Hooking engine functions can conflict with other mods that modify the same functions. Use CommonLibSSE‑NG’s trampoline system or Address Library + SKSE trampoline to safely install hooks. ### Finding exact addresses You will need to look up the correct vtable indices or Address Library IDs for your Skyrim version: - CommonLibSSE‑NG provides `RE::VTABLE_*` constants for many classes. - Or use Address Library + `REL::Relocation` to patch by ID. --- ## Summary flow 1. **Plugin loads** → install hooks on `TESEffectShader::Play` and/or `MagicTarget::ApplyHitShader`. 2. **Game tries to play a shader on the player** → hook detects `IsPlayerRef()` and returns without calling original. 3. **After loading a save** → run cleanup to stop and remove any shaders already attached to the player. 4. **Result** → player no longer displays magic visual shaders, while other actors are unaffected. This is the standard logic used by mods like “No More Glowing Edges” and “Remove Spell Effects”.
