2D-to-3D -- TRELLIS 2 on 6 GB of VRAM

We continued to push the 2D-to-3D, after installing TRELLIS 2 locally on May 2nd, at Quelab on a computer with only 16 GB of VRAM -- by following the instructions in the YouTube below :
Normally TRELLIS 2 requires 24 GB of VRAM to generate 3D files "with textures and color" in ComfyUI.  However Aero-Ex quantized a version into TRELLIS 2 GGUF that will work with as little as 6 GB of VRAM.


This system works pretty well, except that the faces can be a bit distorted after the reduction:

MOREOVER the original 2D-to-3D resulting file is huge -- 102.65 MB for the Venus sculpture above -- which is too big for Augmented Reality.  So I reduced the byte size with the follow sequence of online programs:


However the reduction facetted my female figure, after bringing the GLB file down to 4 MBs (and the download compressed file is only 1 MB)
  • PLUS , oddly enough, the resulting GLB would not open in BLENDER (at least not without an KTX addon):

There are also ways to decimate and reduce the polygons in BLENDER:
