This is what I do. It’s been really helpful for taking existing FBX files and handing them off to the agent + Python Blender API to analyze the geometry, convert to GLBs, etc.
What model you using? With codex and gpt-5.4 set to xhigh (and now gpt-5.5) seems to have zero issues helping me with rigging and fixing glb/fbx models, works as a charm. One time I instructed it to iterate together with screenshots because it was a gnarly task, but usually it figures out everything even when headless.
