Adding ambient occlusion effects

- Having got to this point in the chapter,…we should by now be pretty familiar…with the use of Blend nodes…in our Substance Designer graph,…which is good,…because that is what we are ultimately going to be using…to help create our Ambient Occlusion effect.…If we zoom into the Ambient Occlusion frame, however,…you can see that we have actually used…only two nodes here.…One is a copy of the Ambient Occlusion Map…that we baked earlier,…dragged, of course, from the Resources Folder.…And the other is yet another Gradient Map node…that we are using in order to convert…a Greyscale Input…to an RGB Color Output.…

Now, whether or not we need to create…baked Ambient Occlusion…from inside Substance Designer…is one of those choices…that will need to be made based on both the aesthetic…and game engine performance requirements…of the game that you are creating.…Because we could, of course,…have our game engine generate…an Ambient Occlusion effect…for all or some of the assets in a level.…That, of course, requires processing cycles, though.…
