Your probably like "This goes in help!!!!!!!!".,well OK I know that. Except it takes years for a person to actually help if any. For some reason after I make a model/interior for my map. When I import it into the map. My player does not collide with it. Some parts of it I will collide (mainly the exterior), but most of it I will just fly right threw it. So what is the answer to my problem? Thank you for reading, and or helping.
