Will it become possible to upload 3D models including textures? I don't know why it's currently not possible – are there already plans for enabling that?
Why is there no info page on Wikimedia Commons about 3D models like STL files? For asking about this, I only found Commons:Category talk:3D models. It would be good to have a place with some info on what, how, and so on.
For example, I found this page useful to convert CCBY models on sketchfab to STL files that can be uploaded to WMC. They lose their textures when doing so. I think 3D models could be useful for many purposes, and probably also for generative AI that can be used to create images of any kind like Stable Diffusion. They would benefit from getting trained on categorized 3D models.
