alt Hacker NewsThat’s exactly how I’ve used tools like Tripo and Meshy.
Use any image generation tool (or any image) and have a multimodal LLM like Gemini extract individual parts of the image “isolate with a transparent background” - then you can use those images for image-to-3d in those tools.
Don’t forget to use low or “smart” poly features otherwise you get too many vertices to the point you can’t performantly raycast etc.
But yeah - it’s there.

Side tangent: Smart Poly is often a paid feature, but you used to be able to steal it for free. Because in order to preview it, you download the GLB in the Network tab.
Some 3D AI providers still leak like that, but Meshy came up with their own binary format that splits the stream up into separate files that are assembled with a response it only gets if you have Premium.
Thought it was cool technology - and wonder if browser games in general are doing stuff like that to protect 3D assets from being easily ripped from the Network tab.

I've found it's actually best to do maximal quality generation and decimate/meshopt to desired budget.
If you're raycasting against your raw art you're doing it wrong anyway, none of the big players do this precisely for the reason you mentioned. And beyond physics meshes, if you're doing anything where performance is a problem you probably want multiple LODs so you have to do this work anyway.
These days you can just ask your agent to build you a LOD pipeline and forget about it rather than sacrificing the art; Claude knows Blender.
