I’m currently working on a very large-scale environment in UE4. The project requires a huge number of repeated interior rooms/buildings, so I would like to create reusable room prefabs that already contain baked lighting information.
Any useful advice or examples would be greatly appreciated!
Anyone?
not sure it this can be done in ue4. lightmaps are level data. so the option you would have is to bake it externally. like blender or marmoset or i dunno whatelse is out there. you could bake just gi/ao or a full diffuse lighting or whatever you require. then just use the prebaked lighting as a texture layer and do some math with your base color. normal mapping is a tricky thing. you’d have to bake multiple directions and use some shader trickery like what the source engine did with their selfshadowing normal maps, i guess.
