Hi, I'm having some issues with smoothing where normals for adjacent faces are different. This affects lighting as you can see here. What settings do I need to be tweaking to affect the calculation of normals on adjacent faces like this??
Think it depends on what your brushes look like, how you used the nodraw options for them and if they're grouped or not. There's also smoothing/normal options on the ConfigUEr tab you could experiment with.
Other things you could try on the UE side is to maybe join the two meshes together, and let UE recompute the normals itself.
