texture-state-animation

该 Skill 提供纹理状态动画的设计规范与验收流程：先对齐并归一化各纹理状态，再按图层分别选择过渡方式，避免整帧交叉淡化与纹理跳变，最后检查导出格式能否复现动画；并附带一个生成过渡方案、标记整帧淡化风险的 Python 脚本。

Metadata

name: texture-state-animation
description: Design and validate texture-state transitions for Blender animations without ugly whole-image crossfades, texture popping, misregistered morphs, or target-engine-incompatible Python-only swaps. Use when animating between multiple source textures, mascot/logo states, style states, lightmaps, decals, or UI skins.

MCP backend

Use when: Texture state animation, texture morphs, material state transitions, image sequence planning, masked wipes, glow reveals, texture registration, avoiding bad crossfades, GLB-compatible texture animation planning.

Before the first Blender call, read ../text-to-blender/references/mcp-backends.md. Prefer official MCP for shared capabilities; preserve the selected backend for the whole task. Tool names in recipes are client/legacy examples: map them through that reference and its agent-host guide.

Texture State Animation

This skill exists because “crossfade several full images” usually looks bad. Texture animation must be designed like motion graphics: registered states, constrained transition channels, and preview gates.

Failure modes to avoid

Whole-frame crossfades between unrelated crops/compositions.
Python frame handlers as the only playback mechanism when export/runtime support is needed.
Texture swaps that change silhouette, camera crop, or scale at the same time as decorative motion.
Mixing aura/background/HUD pixels into the avatar surface texture unless that is the intent.
Morph pulses that break accepted geometry constraints such as constant depth.

Workflow

Register states first: crop, scale, align, and color-normalize all source states into one canvas and one semantic mask.
Classify pixels/layers:
- avatar surface/base;
- facial decal/features;
- glow/emission accents;
- background/aura/context;
- HUD/circle elements.
Choose transition type per layer, not one global blend:
- avatar surface: hold, shimmer, subtle value/roughness pulse, or masked dissolve;
- face features: hold or short opacity fade;
- glow accents: emission pulse / traveling highlight;
- aura/HUD: independent orbit/dash/dot animation;
- background: separate plane/compositor, never baked into avatar unless requested.
Use export-compatible channels when needed:
- keyframed material values, opacity, UV transform, shape keys, object transforms;
- image sequence only if target supports it;
- avoid Blender Python handlers for final GLB unless the target runtime will recreate them.
Render a contact sheet and flicker report before calling the animation acceptable.

Acceptance gates

Each texture state is registered to the same bbox/landmarks.
No full-canvas crossfade is used unless state registration and semantics match.
Avatar silhouette remains stable unless the story explicitly calls for a morph.
Context/aura elements are separate from the avatar material.
The exported format can reproduce the animation, or limitations are documented.

Scripts

scripts/texture_transition_plan.py creates a transition plan from source states and flags risky whole-frame crossfades.
