Hi,
Is there a way to force multiple maps to share the same lightmaps? I have multiple missions with the same lightning (lighning setup is the same and 90% of geometry is the same as well) and there is no reason to have the same lightmaps multiple times. This would save a lot of space. As long as I know, unreal holds a map’s lightmaps within the map (*.umap) which means that if I have 2 maps with the same lighting, their lightmaps are saved separately. I’ve attached an image to see what I mean:
