Dirt distribution values

[javierrentas]

Please, can you change the dirt distribution value to be able to add a negative number?
I like to use the distribution value to add more contrast to the dirt as in 3ds max, but I found that I could not add negative numbers.
Please let us do that.

You can try adding a color correction with a white color in the occluded color and increase the intensity over 1 should make your dirt stronger.

Thank you for the workaround. Yes, that is one way to do it. But it is easier to add just a negative number to the distribution, how we could do in other V-Ray, like in Max, Blender, etc
