Hey guys i have an issue with lightmaps/shadows. I have created 3 walls in a group inside 3ds max and created UV channels 1 and 2. When i export the wall into unreal engine 4 i increased the lightmap resolution to 1024 and pressed build. I get a problem when one shadow covers 2 walls as the shadow does not build in the correct place when the two walls meet. I have provided a picture of the issue
If anybody can please help me i would be really appreciative!
