6 Gearing up for the painting stage
Now I process my rendering, focusing on Final Color, Alpha, Element ID/Material ID, Total Illumination, Ambient Occlusion, Normals and a Depth pass. I’ll use my passes to achieve the best possible starting point before starting to put my brush on the canvas. I use my Ambient occlusion Pass and put it on a Multiply layer in Photoshop, set to 25 per cent Opacity. The Depth pass is used to create a fog layer. I render the people in my scene separately, so I can easily take them out of the painting later on, if necessary.
