OpenUSD Explorer transparent previews

Transparent PNG derivatives of original OpenUSD asset thumbnails, prepared for OpenUSD Explorer. The original viewpoint and framing are preserved. No 3D model files are hosted here. Native-alpha previews remain links to their source datasets.

Preparation uses the local Python package rembg 2.0.86 with BiRefNet-general and edge-color decontamination on NVIDIA T4. It does not use a hosted removal API. The model's SHA-256 and batch settings are recorded in the preparation reports.

All cutouts were screened on contact sheets, with larger source/cutout comparisons for flagged and selected detailed objects. This is thumbnail-level QA, not a guarantee of physically correct transparency: glass can retain shading baked into the original image, and thin geometry is limited by source resolution.

Attribution and licenses

Each manifest entry identifies its source dataset, creator through the source URL, exact source revision, original image URL, declared asset license and image hash. Attribution and original license terms remain applicable to each image. An absent license field means the upstream metadata did not specify one; it does not mean public domain. Native linked images are not redistributed in this repo. No single application-code license is applied to this mixed-source collection.

The transformation is background removal, with any per-image correction described in its review record. Source asset owners retain their respective rights.
