At start it created simple shapes for me to have something to work with.

My goal was to create 3d shapes out of math curves. LLM wrote bunch of scripts, that generated 3d models for me.

Usual problem with LLM is that it needs good grip and traction on problem, to actually work. It is fine with text and code, and images, not so much with 3d objects.

Not sure whst is your workflow, but perhaps give llm ability to see rendered game without your help. It is a problem with integration and automation.

Curious, what's issues you encounter that LLM or Blender forum can't help? I also still learning Blender though not complex like yours (Product and Architecture), and LLM help me so much, it is save times that I previously will search on forum and YouTube.

I don't think we should expect to short-circuit learning for everything. Fumbling in Blender for hours on end is part of the process and what makes you good at it in the long term, much like grinding exercises in math or physics.
