A custom shader workflow like Unity, Unreal or other engines

You can write shader with glsl and .json, then they become custom node in Blender and can be applied to multiple projects with different textures

No files, tests, or entry points are named. Start by tracing the existing Blender shader and custom-node workflow, then clarify how GLSL and JSON inputs should become reusable nodes across projects with different textures. Done should be defined as a documented workflow that supports those inputs and reuse.
