Description

Hi,

When I use the provided scripts to render Objaverse-github dataset, there are lots of abnormal rendering results. I looked into the downloaded raw data and find out that some portion of assets lack texture information so that Blender assigns a default color. I'm wondering how do authors deal with these data in the original Trellis preprocessing stage. Thank you~

Research direction

Start with the provided rendering scripts and inspect how the Objaverse-github raw assets are loaded into Blender. Compare this path with the original Trellis preprocessing stage, focusing on assets that lack texture information. Done means the handling of textureless assets is understood and abnormal rendering results are addressed or clearly documented.
