4808	Add GLTF saving of textures	Tom Goddard	Tom Goddard	"For NIH 3D model repository NIAID wants to use GLTF.  Currently we output vertex colors into GLTF.  Many 3D modeling software packages don't deal with vertex colors and only support texture colors.  Need to check which packages.  Babylonjs.com web viewer handles gltf vertex colors.  Others to check out are Blender, Maya, Cinema4D, Unity.  Some apps use a plugin to read gltf.  Kristen Browne at NIAID has a good bit of experience wrangling the ChimeraX models into other software.

It would help make more usable exported models if ChimeraX could write texture colors into GLTF.  We can currently do this in a roundabout way with OBJ format as described here:
