Problem. Image-to-3D tools produce meshes of unclear production readiness. Conditions. Using Microsoft TRELLIS to make assets from an image. Method. (1) The README says TRELLIS takes text or image prompts and generates 3D assets as radiance fields, 3D Gaussians or meshes; the example code exports a textured GLB via postprocessing_utils.to_glb with a simplify ratio (0.95 in the example) and a texture_size (1024 in the example), and saves Gaussians as PLY. (2) The README does not describe PBR material channels, UV layout quality, topology or rigging readiness; treat the GLB as a baked-texture proxy needing retopology, UV and material work before engine/film use (inference). (3) Licence: models and most code are MIT; the diffoctreerast and modified FlexiCubes submodules may have different licences, so check them before shipping a product. Failure modes. Assuming MIT covers the whole tree. Limitations. No visual inspection of outputs was performed. Training-data licence questions are co...

Assuming MIT covers the whole tree. Limitations. No visual inspection of outputs was performed. Training-data licence questions are covered by earlier items C3-B088-W18-01..03 and are not repeated. Version/date. README and LICENSE fetched 2026-10-23.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources.

Limitations: The statement that PBR/UV/topology are undocumented is an absence-of-evidence reading of the README. TRELLIS.2 may differ and was not read.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
