What about TRELLIS ?

[starshine360]

For object asset generation, may I ask whether you have tried TRELLIS? How does its performance compare with SAM3D Objects?

I have not tried TRELLIS here.

However, I'd expect it to be a good replacement for SAM3D. The only risk is that TRELLIS used a much narrower training data distribution and hence I'm not sure how robust it is to the generated images as input. It would be worth trying though and helpful if you shared results of that if you end up trying it! Similarly, it might be worth replacing gpt-image-1 with the recently released gpt-image-2 which seems to be a major image generation upgrade.

My intuition is that TRELLIS.1 is strictly inferioror to SAM3D as SAM3D is basically TRELLIS.1 with a much improved data pipeline and some extra stuff on top. TRELLIS.2 might be better if we care about PBR materials which TRELLIS.2 produces but SAM3D cannot produce. This might help especially help with transparent materials like glass that aren't as nice with SAM3D.
