Vray Dirt Maximum Radius 100?

[ErwanL]

Hello,
I don't see any difference with any value above 100 for the radius of the Vray Dirt.

With any value higher than that it just renders the same as it would with 100.

Is that a known limitation or am I doing something wrong?
It gets problematic for large scale scenes.

Nevermind, I have been doing more tests and keep finding different values where cranking the radius stops changing renders.

I realized the issue isn't from the Dirt shader, but from what I was expecting it to do.

I thought it would act a bit more like a distance texture, and as a result get darker and darker as I increased the radius, while in fact it will only get darker if there is another object occluding that was previously ignored because too far.
