Two other important features for 3d-tiles export would be
- to support using multiple texture
image-layers, when one Model has been textured with multiple texture image-layers (texture01, texture names, etc). Demo here - to support packing
labelsfrom classification (either via the AI classification tool orTransfer labels from images) into tiles geometry since, quote glTFEXT_structural_metadataandEXT_mesh_featuresallow for storing and querying feature information from geometry attributes and textures. Demo here
See this showcase post of the 3DTilesRendererJS by Garrett Johnson for an illustration of both multiple texture layers and extra geometry attributes.
