I've built something like this. One issue is that LLMs are actually terrible at writing good shaders. I've spent way too much time trying to get them not to be so awful at it.

I tried getting any sota llm (GPT 5, Opus 4.6, Deepseek V4 pro, glm-5) to write a Metal 4 shader for a bottle usdz and none of them got it right. They screwed up the normals and textures , total mess. I tried it to do it in Metal 3 and still crappy.
Just curious if you've tried GPT 5.5 Pro?
