Additions:
To simulate Ambient Occlusion create an FXFilter to FXMap box and use it to convert your height map into an Fx-Map. Then parametrize a HSL filter with it and apply it on your diffuse map. Invert the HSL filter gradient (i.e. make the black gradient key white and resp. the white key black) and move the luminance slider on the left according to the amount of light you need.
To obtain a more scattered effect, you can also blur the height map by passing it through a new uniform blur filter before the FXFilter to FXMap.

Deletions:
To simulate Ambient Occlusion create an FXFilter to FXMap box and use it to convert your height map into an Fx-Map.
Then parametrize a HSL filter with it at the end of your diffuse map compositing graph.
Invert your filter gradient and move the luminance slider on the left according to the amount of light you need.
To obtain a more scattered effect:
you can also create a colorize filter just next the FXFilter to FXMap and then plug on it a new uniform blur filter and set it the way you want.
Then create another FXFilter to FXMap an plug the uniform blur filter on it.
Now coninue the same way than ealier:
Parametrize a HSL filter with it at the end of your diffuse map compositing graph.
Invert your filter gradient and mobe the luminance slider on the left in fonction of the effect you need.

This tutorial assumes you have already created a graph with a diffuse output, part of which renders a height map, which may be used e.g. to compute a normal map, or as an input for an emboss filter.
