I did not mean to sound hostile. It's just very frustrating as there seems to be so many parameters to adjust that you truely have to be a junior Steven Hawkins to be able to set comething up as common as colored glass. I like modelling in Maya but ligthing and rendering are a real chore. It seems to be far more complicated than in needs to be. It's almost like they are trying to force artists to pay for training seminars and tutorials to be able to use something that could easily be put into a more user friendly and less Einsteinian interface.
