Hi, Not sure I'm in the right subsection but I'll give it a go I just purchased Realistic Outdoor Environments & I would like to consult a table of contents if such exists. I need to look at the bit that talks about speeding up your rendering sooner rather than later, so if nothing else, do you know where that part begins (he mentioned he would be talking about it later in one of the early lessons - I'm on lesson 8 now) Thanks TEvans
