Even if this is “only” mesh autocomplete, it is still massively useful for 3D artists. There’s a disconnect right now between how characters are sculpted and how characters are animated. You’d typically need a time consuming step to retopologize your model. Transformer based retopology that takes a rough mesh and gives you clean topology would be a big time saver.
Another application: take the output of your gaussian splatter or diffusion model and run it through MeshGPT. Instant usable assets with clean topology from text.
