I encountered the problem of displaying the baked light in the engine on channel 2 of the UV when I create a batch group for this model. And the strange thing is that this problem with displaying the lightmap in Play, and everything is fine in the engine editor. Maybe someone can tell me what the problem could be? I’m attaching the link to the project below.
Unfortunately the batching and the lightmapping do not work together. We have a ticket for its improvement, but it has not been done yet: Possible improvements to Lightmapper · Issue #3430 · playcanvas/engine · GitHub
Thank you for your answer
