I made this very simple SU model and exported as a fbx and imported to UE4. UE4 generated what look to be clean lightmaps, I’m no expert though. Anyhow, I set the map resolution to different settings and it still has a problem.
I do Archviz for a living and was hoping to have a workflow of SU to Blender to UE4 but that’s a no go as something happens to the SU model in Blender when it exports as a .fbx that UE4 says that it has no triangles which isn’t true. So, I tried SU export as .fbx to UE4 and get this. I can’t use software that is hit and miss in combination with each other so if I can’t get a work flow working with these two options I’ll have to look into building models in Blender which I really don’t want to do as SU is my preferred modeler for building shells.
Anyhow, any advice appreciated.
