Shadows not matching up with corners?
Updated Question I've been using blender to create my meshes and export to fbx. When I import them I get a message saying "No smoothing group information was found in this FBX scene. Please make sure to enable the "Export Smoothing Groups" option in the FBX Exporter plug-in before exporting the file." Blender doesn't seem to make use of smoothing groups, and there is no level of control for them in the exporter.
The mesh appeared in the editor as though it was just fine so I kept using it to see what would happen. When I finally got my walls put together, I noticed the corners of objects that are supposed to meet the shadow don't. I even tested this with a new project. I put a bsp on the ground and I get decent shadows, but the corners still aren't matching up.
This doesn't look like a Smoothing Group issue, but rather that you need to increase your lightmap resolution. The default resolution is 32, and if this is a single mesh you will need a higher resolution. Try something around 128, 256, or 512. This should be enough, but you may also need to go up to 1024. Anything much higher than that and you would probably want to break the mesh up into smaller chunks to use the Lightmap UV space effectively with a lower resolution.
