Intensity multiplier in dirt map

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?

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 :slight_smile: 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.
