Rotating Brushes  --  By Nicholas Ivan Fisher (fishen@rpi.edu)

TEXTURES: 	Doesn't matter...use whatever texture you wish that seems
		right

Entities:	func_train, path_corner

What to Do:

	Make the brush that you want to rotate.  Copy that brush and use
	the rotate function of your editor to rotate it a little bit
	(i.e. 5 degrees).  Do this until there are just enough brushes so
	that the next rotation would look the same as the first brush
	(i.e.  120 degrees for 3 fan blades, 90 for 4, 45 for 8).  Now
	select the first copy (all of it) and make it into a func_train.
	Do the same with the rest.  Make 1 path corner for every func_train
	that you have (4 trains = 4 corners) and set them up in this
	fashion:

			2	3	4	
		1	8	7	6	5

	With 2 & 8 occupying the same space (overlapping.  Same with 3 & 7,
	4 & 6, etc.).  Then just set it up so that train 1 goes to corner 1,
	train 2 to corner 2, etc.


Options/Notes:

	If you want to make this better you should make sure that the textures
	on each brush line up correctly and are rotated a little with each brush.
	I didn't do that and thus it appears that the texture is moving some.
	Also, be very careful with the lighting on these.  Otherwise you could get
	dark spots, flickering light levels (like I have), or worse.

	If anyone uses this and combines it with a wind tunnel let me know.  I think
	that it might look really impressive  (like in all of the movies with the
	big industrial size fan that's sucking people up and then gibbing them).


Have Fun.
