Babylon Sandbox not keeping lightmaps on export


When a lightmap is added to a model in Sandbox and the model is exported, the lightmap is not kept. Is this not available?

And is there any way to embed lightmaps in a GLB with any other exporter?


Welcome aboard!

To my knowledge, lightmaps are not supported in glb/gltf files yet. I think some discussions are taking place on Khronos side to add an extension about that but it’s not done yet.

At the moment lightmaps are not supported in GLTF specs. Below there are several forum links which could be helpful.


Also, a playground example: (available through this doc page).
