- VFXAssetParser/VisualEffect 渐变烘焙改 R16G16B16A16 半精度浮点(不再 max-normalize, 保 HDR 强度); writeRenderData 端配套 clamp(0,64) 直通 - VisualEffect.processInitialize 重解析事件 ID(组件 initialEvent 改值后不再 no-op), initialEvent 空值回退 asset.initialEventName - VFXRenderer 移除节点级 mesh define 并集,改 _syncMeshAttrDefines 按系统材质实例 精确管理(多 mesh 能力不同时并集会让 shader 变体引用缺失顶点槽,WebGPU 建管线失败) - BlueprintPixelVertexVFX.glsl: v_TexIndex/v_NormalizedAge 声明移出 VFX_INSTANCED 守卫 注: 本日 bundle 侧新增的 rateProperty 属性驱动/属性默认值双形态/propertyOverrides 帧检测等修复的源码 backport 仍待后续(bundle 与源码差异清单见插件仓提交) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
… VisualEffect(VisualEffect 支持 Texture2D/Gradient 暴露属性运行时 override——新增 setPropertyTexture/setPropertyGradient/_bindPropertyTextureToShaders，_applyPropertyOverrides 按值类型分派 string→texture、{stops}→gradient 并恢复默认，_propertyValues 加 defaultCached/defaultRawGradientStops 备份，对齐已提交的引擎 bundle)
…lus accumulated VFX system fixes (修复 materialize VFX 雕像渲染:VFXRenderer 新增 AlphaClip 渲染模式做 Alpha 裁剪+写深度对齐 Unity cutout 让雕像实心、getCustomShaderMaterial 补 EMISSION 宏让自定义 Lit 蓝图 shader 的 HDR 辉光/emissionMap 经 pbrFrag #ifdef EMISSION 生效；含 ShaderExpressionEvaluator/VFXAssetParser 等 VFX 系统累积修复) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> (cherry picked from commit f07b630)

主要修改：VFX materialize 雕像渲染对齐 Unity
UNI VFX「Energy DM」materialize 溶解雕像在 Laya 端两个根因修复（与 LayaAir_3.4 同源 cherry-pick）：
半透穿透 → 实心：Unity URP 用
Transparent + _ALPHATEST_ON + ZWrite On（Alpha 裁剪 cutout，alpha 是step()二值 0/1），Laya 之前走 alpha 混合 + 不写深度 → 前后/内外面乱序混合，雕像发灰穿透。VFXRenderer.applyBlendMode新增AlphaClip模式（alpha 混合 +depthWrite=true，对齐 Unity ZWrite On），配合 shader 端 alpha test discard → 雕像实心、深度正确。HDR 辉光 / emissionMap 不渲染：自定义 Lit 蓝图 shader 已算好
inputs.emissionColor（含溶解边缘 HDR 辉光），经SurfaceShading→pbrFrag的#ifdef EMISSION color += surface.emissionColor输出，但getCustomShaderMaterial漏加EMISSION宏 → 整段 emission 被门控跳过。补上EMISSION宏（Unlit 路径不受影响；Lit 无 emission 时加 0 无害）。⭐ 通用修复，所有 VFX Lit 蓝图 shader 的 HDR 辉光/自发光都受益。本分支包含的 commit

UNI VFX Energy DM White/Purple 在 LayaAir 预览中实测：雕像由半透穿透变实心、溶解处出现 HDR 白色辉光块，与 Unity 参考效果对齐。
