AO option can't find it

As I can remember there was option for activating AO, but can’t find it anymore, is that out?

There is the VRayDirt texture - is this what you need?

No, I might mix it with 3dsMax options… This is from 3dsMax help:

Ambient occlusion

These controls allow you to add an ambient occlusion term to the global illumination solution.
On - enable or disable ambient occlusion.
Amount - the amount of ambient occlusion. A value of 0.0 will produce no ambient occlusion.
Radius - ambient occlusion radius.
Subdivs - determines the number of samples used for calculating ambient occlusion. Lower values will render faster, but might introduce noise.

Yes, it’s a 3ds Max thing for now; will be adding them to the Maya builds shortly.
