Black blotches

I started in Revit , exported to MAX, have studio installed and exported to UE4.19 I thought this would streamline the modeling of architectural spaces. there are black anomalies’ in the model that I cannot remove, all these surfaces should be the same color shiny white. What am I doing wrong?


Usually those black parts are lightmap problems… or they are not covered at all, or they are overlapping, or might be those normals are flipped!

are any of the meshes your having issues with the ones that there are warnings on? if so re unwrap your meshes so they arent overlapping.
