Well not really sure what you're talking about here wrt nodes (adding in arbitrary rotation/zoom sounds great in theory if all you're looking for is a lazy susan or spinning exorcist heads), but the next steps will likely be more around ensuring sane symmetrical topologies, better UV maps, and automatically building rigging (FK/IK) to allow for easy animation.

I meant rigging, but I'm a layman so I don't know the terminology. But yes, symmetrical models with simpler meshes and better UV maps would definitely be needed to make it work as I'm imagining it
Mixamo is pretty close to this (Auto-rigging tool from Adobe). https://www.mixamo.com/#/

It's limited to mostly human shapes, but I've personally used it in combination with the 3d-pack in comfyUI to generate 3d models and rig them, starting from a text prompt.

Trellis looks like a more capable model generation tool than TripoSR and marching cubes, which is what I was doing in Comfy: https://github.com/flowtyone/ComfyUI-Flowty-TripoSR - It worked but models ended up having a slightly "melted wax" appearance.

This type of flow is definitely already here for low quality assets (think mobile games). I'm excited to go play around with Trellis, looks like a significant bump up in quality.

Super cool stuff! Thanks for sharing. It's exciting to see how fast this space is developing.

Hopefully one day we get some open source alternative to Mixamo that plays nicely with the rest of the open ecosystem.
