Ok, First off... I didn't know that existed. SO BIG THANK YOU. I downloaded the mesh, but same issue. If you are using goods map pack, the light blue area (basement middle?) will not render correctly. I have even tried to patch work it together and there is something funky that stops it from rendering right.
well doors you would want to check that you don't have "ignore scripted doors" selected if it is a scripted door
and you would want to check your "trigger distance" for your door clicking. sometimes the "click" for a door is further away than the default 20 value
