Hey Eric, Are we going to leave the walls using the same models? If so let me know cause I have a solution to the z fighting issues. Basically the fix is just where the walls overlap, scale down one of the overlapping walls a small, unnoticeable amount. That makes it so the 2 walls dont have the same Z value and thus no z fighting. If we are going to be changing the models for the walls though that's a moot point and i'll leave them alone.
