I not sure what I did but all of a sudden auto holes won’t work. It was working fine until I tried to add windows and it started to do this(see image) the CRTL_hole is somehow merging with the room model and the back material is being applied to it.
this is what happens when I move the entire window into the room
Then for the doorways I already had I couldn’t re-apply the auto hole. To work around this I simply deleted and then re-applied the boolean manually and that worked on my doors from before the issue started. When I tried to add new windows/doors this happened again(see image). Has this happened to other people?
