blb doors or animated doors?
I'll make a vent that looks like the one in op. Obviously scaling it so you can crawl through.Ah! I didn't think of that, thanks!The pack is going to have almost 30 doors. Is this too much? I probably need to splits the half doors into their own add-on.
a hidden door (looks like a normal brick)
EDIT: What about arch, but not full arch doors?:
EDIT: Since they work the same way.... can you make window shutters?
