Help with displacement

[aiden_humphrey]

Hi there,

I've been using Thea render professionally, and am considering moving over to Vray. I'm doing a simple test to get displacement working.
I created a corner, grouped it, and then applied the displacement modifier to the group.


I applied a brick material to the group. (I did not apply this directly to the faces, but only to the group as a whole.)




I made sure displacement was switched on for this group and also turned on "Keep Continuity."
I'm using RTX rendering (3090RTX GPU). I should mention I get the same problem on CPU and CUDA as well.



Here is the output:



I get this whether I'm using interactive or final render. CPU, CUDA and RTX all lack displacement.

What am I missing here?

Hi aiden_humphrey,

The Displacement modifier needs a separate texture to work.

The texture placement of the material applied to the object is respected by the displacement but the displacement texture itself is separate.
Also note that the library material textures are not designed for displacement purposes and might produce suboptimal results.
In the my example scene I've grabbed one of the scanned displacement texture from textures.com.

Konstantin
