Blending materials with displacement maps

[ethan_prodin]

Hi, new user here
I have a 2 generic materials that I’ve applied diffuse, bump and displacement maps to, but when I try to use blend material it removes the displacement maps and it’s very flat.
Are there other options I can use?

The first 2 pics are the separate materials, and the last is with the blend applied

Hi,

Try using the new Displacement modifier from the V-Ray menu.
​
This will put the Displacement directly on the geometry, regardless of the material applied to it.
Then for the Displacement Map, you can blend 2 source maps with the Mix Map texture.
