I picked up the book The Invisible Art, and was blown away to see how much of film is actually painted! Matte Artists deserve my deepest of respect. I decided instead of spending forever tweaking at materials for my mountains, why not just render them out, and use them for reference to paint over individually? 99% of my shots do not have camera moves so I decided to do just that. Take a look at a side by side comparison of render to matte.
