nan 32bcd45d7b Add new node asset scripts for geometry and shader operations
- Implemented `build_mesh_plane.py` to create a geometry node group for mesh planes with customizable parameters.
- Created `build_shadeless.py` for a shader node group that displays color without scene lighting while preserving shadows and reflections.
- Added `validate.py` to validate the integrity of the newly created node groups and their inputs.
- Introduced `validate_cutout.py` to ensure the functionality of cutout node groups and their dependencies.
- Developed `validate_mesh_plane.py` to test the mesh plane creation and its modifier settings.

节点资产

AnyImage 将稳定、可复用的 Geometry Nodes 和 Shader 节点组构建到 O_AnyImage.blend,运行时按名称加载。Depth Plane 节点图是例外:它由 Python 在当前 .blend 中按需创建。

构建与加载

flowchart TD
    Scripts["tools/node_assets/build_*.py"] --> Build["Blender 后台构建"]
    Build --> Blend["assets/O_AnyImage.blend"]
    Blend --> Loader["operators/common/node_asset.py"]
    Loader --> Modifier["运行时 Node Group / Modifier"]

使用 Blender 而不是普通 Python 执行:

BLENDER_BIN="/c/Program Files/Blender Foundation/Blender 4.5/blender.exe"

"$BLENDER_BIN" --background --python tools/node_assets/build.py
"$BLENDER_BIN" --background --python tools/node_assets/validate.py
"$BLENDER_BIN" --background --python tools/node_assets/validate_mesh_plane.py
"$BLENDER_BIN" --background --python tools/node_assets/validate_cutout.py

build.py 从空 Factory 文件开始,依次构建 O Mesh Plane、O Shadeless、四个 Cutout 内部节点组与公开修改器节点组 O Image Cutout,再保存唯一资产文件。O Image Cutout 用 Menu Switch 包装四个内部组;运行时 Loader 只加载这个稳定入口,Blender 4.5 根据 Shape 菜单依赖只显示当前分支实际使用的输入。

验证范围

基础验证检查发布资产清单、节点树类型、Modifier 标记、接口顺序和 Fake User。专项验证继续检查:

  • Mesh Plane 的接口、细分、Thickness 和几何求值;
  • O Image Cutout 的公开接口、Shape 菜单和四个内部组的依赖关系;
  • 节点不重叠、主要连线保持从左向右;
  • 局部 Group Input 未使用输出隐藏;
  • Cleanup 只在四条分支之前执行,Smooth 只在菜单选择之后执行;
  • Repeat Zone 数量和四种 Shape 的关键几何求值稳定。

节点资产接口变化时,应运行全部四个 Blender 入口和完整 Python 测试。只修改 Python、Markdown 或打包逻辑时无需重建 .blend。Blender 自动生成的 .blend1 等备份不属于发布资产。
