Description

Thanks for releasing this great work!

I’ve been testing TRELLIS-2 and noticed that while the geometry is a significant improvement over TRELLIS-1, the color consistency remains an issue. In many cases, the output colors differ noticeably from the reference images. I’m wondering if this is due to inaccuracies in the PBR estimation, specifically regarding the base color (albedo) not being as precise as expected?

Research direction

No source file, entry point, or test is named. Start by reproducing the color difference with the attached reference images and tracing the PBR estimation, especially base-color (albedo) output; done would require identifying the cause and establishing that the resulting colors match the reference more closely.
