Dirty Chrome Material

[Nicolas Saba]

Hey Guys,
Im trying to create a dirty chrome material to my car bumper, i want to make the effect that some dirt us stuck on it.
So i tried creating it using blend, and corona multi layered material,
the thing is im getting red polygons/ splotches/ weird shapes instead of the dirt.

Any ideas how to fix this? and does anyone know what seems to be the problem?!

thanks in advance

Sorry for the delay,

Did you use AO for blending between chrome and dirt materials? If you apply this material to other model (teapot primitive), does it behave the same? Can you upload material (without textures)?

i noticed that the red stuff is somehow related to the uvw map channel, when the channel is set to 2, i get this result, when its set to 1 i get normal results, but im using the same material on the car, but instead of chrome i have carpaint here is a preview
