Combining textures for displacement

Hi everyone,

I’m trying to get a transition done from sand to rubble. Blended the different materials with vertex paint in a Vray blends material alright, but when they were combined displacement isn’t working anymore for each material; not in the material slots nor with the modifier.
since displacement with transition works fine with the modifier with a simple grey material I’m guessing it’s either the blend material that breaks it or the different mapping channels?
What’s the proper procedure this?
Thanks!

Can you show me some examples just to make sure I understand the problem?

Best regards,
Vlado

Do you use 2D Displacement? It only works with one channel.

That must have been it. Now the displacement maps in the materials work again. How embaressing… thank you!

Correction. What I thought was the displace were the normal maps…
Displacement with a VrayBlendMtl in another VrayBlendMaterial doesnt seem to work… is that normal? Somewhat unfortunate…
