Quake3World

I am trying to make a brush rotating arround it's own axis. I don't understand how I can define the rotation's radius and neither how to set the rotation's center.
I checked the gtkradiant manual and read that func_rotation brushes/models need an origin brush. My question now is: What is an origion brush?

The origin brush is a common texture. So if you look under the 'common' directory in your textures it'll be there. You'll want to make a square brush, apply the origin texture to it, and position it in the middle of what you want to rotate. Then you select it all and apply it as a func_rotation. You can also set the axis of rotation in the func_rotation parameters.
