Description
Hi @JeffreyXiang , thanks for your impressive work on TRELLIS.2 !
I noticed a significant quality degradation when testing TRELLIS.2 without background removal. The output exhibits severe artifacts and missing geometry (holes).
As a baseline, I tested the same input image (with background) using Hunyuan3D 2.1. It reconstructs the scene correctly without such issues. This suggests TRELLIS struggles to interpret the complex scene/background.
Image 1: TRELLIS.2 without background removal - Shows artifacts (the sofa)
Image 2: TRELLIS.2 with background removal - looks good
Image 3: Hunyuan3D 2.1 Result - Shows correct generation.
I'm wondering:
- Is this sensitivity caused by the o-voxel representation design or the training data distribution?
- Do you have any suggestions or workarounds to make TRELLIS robust to backgrounds (walls)?
