Doors blue ball missing

That blue ball which you see when you select door is missing how to get it back?

It’s probably not missing but you moved it far away it’s origin.
Select the door, do ctrl shift E and it should put 3d view on the ball, you can then use the top view to move it back.

And in case it’s really missing, just put the door to func_detail and put it back to func_door_rotatin

Also make sure this is toggled on.

Create your brush with the hole in it before turning the surfaces into displacements. Make sure you have all vertacies line up such like this: this is a good tutorial for holes in displacements jump to 20.57 :slight_smile:
