How do you use a dirtmap with a bitmap? I can't for the life of me figure it out.

Dirtmap
I have brick that I would like dirty. I want to apply my dirtmap over my brickmap. I usually render out a OA pass and multiply it in PhotoShop, but I am trying to avoid the extra work.Bobby Parker

Well, I'm normally using dirt in blend material
Base "clean" material (brick in your case)
-Dirt material - masked using Vray-dirt
That way I can control what kind of dirt I get. Dirt is not just darker.
In some cases it could be lighter. Like dark stone where you have dust
and sand in small angles. Sometimes it's totally different kind of material.
Like shiny metal with rusty bumpy edges.
Dirt should be used to mask other material to wanted areas. Not
using it as color corrector etc.
Just my opinion.
(...and don't be afraid to increase dirt samples alot. Like 100)

I'd tend to do something similar larsson except I'd use photoshop for my dirt - I normally have my clean image, dirty image and then use some photoshop dirt brushes to mask between the two - You can use the masks in different ways to drive your materials quite nicely although it takes far more hand uv unwrapping and so on.

Dirt textmap in the Blurbeta plugin pack is good too.

OK. You guys are helping, but I am getting stuck. The image below shows a box (1) and a poly (2). Both have the same material, but both are reading differently. The box (1) is a test and is working and the poly (2) is a wall that I want to make dirty. Am I missing something?

Mapping coords was it. I thought dirt ignored mapping, but I am using a map to control the dirt so it makes sense.Bobby Parker

Now why not just put a dirt texture in the radius slot and your texture map into the unoccluded color slot? it seems to work just fine.Bobby Parker

Can someone take a look at this file and let me know why I can't get my dirt to work? I think it is a scaling issue, but I can't figure it out.
