renderPathes
==========================================

Automatic setup of the correct rendering pathes for images according
to Pipeline standards. It is ment to work with VRay for Maya exclusively.
This is a very simple module, it basically only determines where renderings
will go to.

Usage
-----

::
	
	from helga.maya.rendering.renderPathes import renderPathes
	reload(renderPathes)

	#Create instance
	renderPathesInstance = renderPathes.RenderPathes()
	#set render pathes for final lighting
	renderPathesInstance.setPathLighting()
	#set render pathes for testing
	renderPathesInstance.setPathTesting()
