Intensity multiplier in dirt map please.

I usually do this in post by duplicating the AO layer.

Try upping your distribution amount to 10 or more - it'll toughen up the look of it!

upping the distribution didnt help

Is there a way how to achieve dirt in ambient light to a single layer, just the AO from this light?

[glorybound]

Here is the elements you can create and use as layers

Yeah, I know that. I just ask if there is a one to use for this purpose, if someone knew Maybe VRay Light Select.

you can put an "Output" before the DirtMap and use the curves or other paramters to adjust contrast and intensity. Works quite well, I often use it.
You can even push it that far to create absolute sharp edges betwenn dirt/clean areas.
