I have imported eight houses from Sketchup to eight different maps. Each house is a lot of groups. I have imported the houses without combining the meshes so I will have good lightmaps.
I have done a LightMass Importance Volume around all the houses. After building the light I get a lot of error messages!
Like - invalid light settings - NULL static mesh property
What to do?
Hope for some help - perhaps some tutorial to learn from?
