Baking an AO map
The process for baking an AO map is very similar to baking a normal map.
- Select your high poly and low poly files as normal
- In the maps pull-down, select AO Map.
- Choose the quality you want, the spread (120 is a good value, but you can go tighter or wider if you want) and the ao distance (different than search distance, this is the maximum distance away from the surface point to look for occlusion. Smaller numbers will be less occlusion (brighter) while larger numbers will generally have more occlusion (darker), a distance of 0 will be interpreted as infinite. ).
- Bake and watch your map be generated
