Dirt doesn't work with dof

As continuing my material tests, I found that dirt is not working with dof.

Can someone confirm or tell workaround?

Dirt + Dof

If you’re using QMC for your AA, it may have something to do with the amount of samples. Someone presented a similar thing a while ago. Essentially, the DOF is demanding too many of the samples and thus making the dirt very low quality/barely visible, so you need to feed it more samples - increase the Max. Check if Adaptive Subdivision gives a different result to confirm this.

Aah, I understand. Thanks for that idea.

I’m using adaptive subdivision sampler.
I’ll try to max up samples next, lets see how it goes.

You could try to use more samples for VRayDirt and see if it fixes it.

Man, that’s a nice material!

Would you share your settings?

Well nothing much to share.

There’s Vray blend material mixing metal material and slightly rusty metal.
Then there’s rusty/dirty metal material with high bump.
These materials are mixed using dirt.

In this newest version all above is mixed with totally clean material using edgetex. That’s how I get clean and shiny edges and corners.

All materials have bump map mixed ueing bitmap and edgetex to get round corners.

Not totally happy yet, but getting there.
I can send material later, but that will be missing all Dosch textures.

These look really cool! I’d also love to take a peek at the material setup. Are you still able to share/show?
