Now it?s time to set your render settings so that you get a good quality result when you bake the Ambient Occlusion later. I?m going to use Mental Ray because I?ve had better results with it compared to the scanline renderer. So assign Mental Ray as your production renderer (render setup > common > assign renderer.) Since we?re using a skylight with Mental Ray we need to enable Final Gather (render setup > indirect illumination > final gather.) Tick the ?enable final gather? box and use the high precision preset. You could use the highest setting if your not happy with your results but it will take a lot longer! You can also increase the sampling quality under your renderer tab. I used a minimum of 1 and maximum of 16 samples per pixel.
