Best way to do bump maps within blended shaders in mr?

Say I have a paint shader, blended with a decal shader using an alpha, blended with a dust shader using a separate alpha?

What's the best way to do the bump map(s)?

Currently I have one for the paint layer and one for the dust layer but it would be ideal if I could add one on top of the overall shader...

This used to be possible using the utility combiner shaders but they were removed from MR for no reason that I can see. The alternative is the Blur utility material. Have a look at this thread I posted a while back.

Thanks for the reply, I was pleased to see this! I just installed it - but I have to uncheck the 'show incompatable maps' box in order to see it in the material editor.

And mr throws up this error (in Max Design 2013):

MSG 0.0 15 MB error: Material "Material #87 ( Utility Material )" not supported by the translator. Will render black.



If I apply it to an object anyway and render (with an Arch design piped into it) - then the object is invisible.

Unfortunately for you, it appears to not be compatible with MR. I've left MR for vray some time ago so I wasn't aware of this. As I mentioned above the MR utility shaders were removed in recent Max releases with no apparent reason whatsoever which is quite ridiculous as they were pretty essential shaders for a lot of users.
