Request UltraShape 1 for Comfyui

Apparently, it's better than Trellis 2 for geometry, but it needs to be optimized https://github.com/PKU-YuanGroup/UltraShape-1.0

I hope VisualBruno will be interested in this. thanks

He explained that various OBJ models can be used, so using trellis.2 as the basic shape and then refining it with it should be optimal

Hi. I tried UltraShape to refine a mesh generated with Hunyuan3d 2.0.

The result was not better than the Refiner node I made for Trellis2.

Look at this example I tried myself:

Hy2.0 - UltraShape - Trellis2

@visualbruno Okay, I didn't know that. I haven't tested your refiner node yet, but it looks great. Thanks for your exceptional work.

If you want to try another "Refiner", I created these nodes: https://github.com/[visualbruno/ComfyUI-Direct3D-S2](https://github.com/visualbruno/ComfyUI-Direct3D-S2)

Can you tell me what settings you are using to get these results? I'm experimenting with the Mesh Refiner workflow, but I encounter the problem that increasing the Resolution will decrease the volume of the mesh.

For example, with a resolution of 512 I can refine the whole mesh, like seen in this image.

If I double the resolution to 1024 I only to get the lower left corner of the mesh as a refined result. I assume that doubling the resolution will scale the model two times in the x,y and z direction. But it seems like the part of the volume that gets remeshed doesn't grow with the model but stays at the 512 size?

If you have an issue like that, just change the "downsampling" to 32 in the node.

@visualbruno Thank you very much. This works.
