Interesting, that was a bit hard to follow because of my own lack of ‘context’ :). But it sounds tough. I imagine since rendering has a visual component that adds to the difficulty for LLM. Though you said it’s measurable, is the measurableness visual? And it sounds like you just sent it off with no direction; but good prompting and direction can go a long way. Is the architecture and design and constraints well documented in the codebase?
