Hi,
I’m doing a couple of test scenes using a simple Sketchup room built like the picture I attached. I went straight from SU to UE4 and let UE4 generate the lightmaps, it worked okay as long as I divided the large walls and floor into 4 pieces and set the lightmap rez in UE4 up high. I had one corner with a light leak but I put another piece of geometry around the corner and it solved it.
