We are seeing strange behavior when dealing with Draco compressed GLTF files that use multiple UV sets. When compressing with Draco, any UV sets beyond the first two are lost. Here is a very simple example using a cube. This behavior can be reproduced using Modo, Blender, or GLTF Pipeline to do the compression.
I realize this isn’t really a Babylon issue but I’m wondering if anyone has encountered this problem before and found a solution?
