Maintaining this page. The authoritative list lives with the app, in
ASSET_ATTRIBUTION.txt and the asset catalog. When that file is updated, this page
should be updated to match. Anything credited here is used under the licence stated, and modifications
are noted where they were made.
Looking for the full list? Every credited asset in the Rex library, 385 of them with author and
licence, is on the
full asset record. This page is the summary.
Rex ships only CC BY and CC BY-SA assets: NonCommercial and NoDerivatives licences are incompatible
with a paid app that modifies its models, so assets carrying those terms are excluded rather than credited.
