how would i cut a flat block e.g. a wall to make a door?

basically, i have created a house on unity, only problem is, i have no idea how to ‘cut’ the wall to create a door. i do not need an actual door, just a hole where it would be, the same goes for windows. help would be much appreciated ^^

You would do it in your modeling software. Unity is not modeling software.

separate that wall in diferent cubes :smiley: then make another for the door! :O. or use a modeling software and be awesome

Or you could use a DepthMask shader to cut a hole in any mesh.
