Static mesh level shadows not building correctly
I have built my level in blender 2.73. It is made up of individual cubes, which when imported into ue4 are changed into a single mesh. When I import and drag the fbx file into the editor, the preview shadows show accurate shadows, just low quality (Img 1). After I try to build the map, there are no errors, however the shadows completely disappear except for a few other meshes (all movable, Img 2 &3). If I set the level mesh to movable then dynamic shadows make it work, but the level is not moving, so I would like to have the best performance.

You need to change the lightmap size of each individual mesh. (open the mesh browser and look for lightmap resolution). Use multiples of two for those values. Most often 16,32,64,128,256 and 512 will suffice unless a mesh is really big then ou can consider 1024, 2048. Higher is not currently possible unless you change some .ini settings.

If they come all in as one object they will share the same lightmap which will have really poor resolution. The solution is when you import the .FBX, look for "Combine Meshes" checkbox and UN-check it. Now they will all come in as separate pieces. Don't worry they will all have the same pivot point, so if you select them all and drag them into your map they will be laid out as you had them in Blender.
