Title:	crowdGen.mel

Name:		Dan McGrath

Date:		currentVersion(12/18/02)

Version:	2.30

Description:
		This is a Mel script that will import multiple files 
		and then randomly place them on the X and Z axis.
		For the sake of speed I have limited the import
		structure to only a ten(10) file maximum. Change it at
		your own risk.

Input:	The GUI created will need you to specify the amount of
		files to be imported. There are seperate check boxes
		for single and multiple file types, as well as a # box
		for a numerical value, up to Ten(10) Maximum.
			
		There will also need to be a designation of the
		folder that the script is going to be look for it's files
		to import. This can be any folder you want it to be, but
		you must only have objects that can be brought into your 
		scene. I suggest ONLY *.mb files. This is the default I 
		have set.

Return:
		You should expect Maya to import and place up to ten(10)
		".mb" files into your current scene. I recommend simple
		objects, for speed purposes (like rocks, buildings, and
		low-poly characters without complicated texturing).


Extra Notes:
		Although I made this script using v4.02, it should work with
		most other versions of Maya without problem. Please understand
		that your use of this script will in no way make me liable for
		any problems or damages that occur to you in any way.
		USER ASSUMES ALL RESPONSIBILITY IN THE USE AND/OR MODIFICATION 
		OF THIS SCRIPT.
		Any questions about this script can be directied towards me at:
		danmcgrath@spatiallight.net or try CGTalk.com, there is a great
		forum for Maya (and other) related questions.
