Hey johnnelsonvfx,

Check to make sure you are not setting the lightmap resolutions of your static mesh objects too high. This can cause your lightmass to crash. ‘Override Lightmap Resolution’ option within the ‘Details’ tab of the ‘SM_Cube’ static mesh setting its lightmap resolution too high. Check to make sure this option is disabled as well.
Trying using a lower lightmap resolution for your meshes. 2048 is fairly high.
Lightmass and static lighting building is a very intensive process that requires a lot of CPU power and RAM to complete.
