Meshes turn completely black after building lighting.

So I was having much difficulty with this as well.

Two things you’ll want to check:

  1. The material’s AO input: if you are using a clamp, lerp, or even a simple scalar, check to make sure it’s not set to 0. It will cause your meshes with the material to be read as completely shaded by the AO.

  2. If your material relies heavily on metalness, you’ll want to use a reflection capture actor. Box or sphere is fine. Otherwise if you’re using static lights then the information won’t be stored anywhere after the lighting has been baked.
