I have a room with around 14 objects that are lightmapped in blender to UV2 channel. I want them all on the same lightmap since this is for mobile and we’re trying to reduce draw calls. I assign the objects to an atlas index of 0, but after baking it creates 6 maps instead of 1. Also after baking all the atlas index’s are changed to 0-5 when they were set to 0 before the bake started. Any explanations on this? I’m also using a LightmapSize script to change the resolution to 2k and Lightmap Extended. Any help is appreciated.
Bake selected vs Bake scene seem to be the culprit here. Bake selected will scale my uv2 channel and reset the index. If I do bake scene everything will bake correctly onto one map.
