Thank you very much younglion
I have had a quick look at this and it looks like just the thing I need to get me started.
I did have another look through the Maya manual and discovered (after I had posted) a tutorial on Global Illumination - I obviously didn't look hard enough but this look more like the ticket.
See I have a few models I did that I would like to re-render using GI to make them look a little more upto date, once I have finished texturing them that is...
Tickety boo and ta ta for a bit...
