I made one half of a level & I’m wanting to copy it and flip it to the other side. How do I flip it without using a BSP object? Because I’ve read you need to use a BSP object to be able to use the geometry tool in order to flip it. I’m using basic objects.
Do you mean “Mirror”? If you go to the Editor preferences, Keyboard Shortcuts section, you can search for “mirror” and assign a shortcut to the mirror-axis operation you want.
