I'm using Blender 3.3.1 under Ubuntu 22.04. I'm a newbie with this application and I'm reading the docs and a lot of tutorials. Given an imported mesh (a cylinder, saved in obj format) I want to displace its surface according to this map:

enter image description here

Hence I set up the material like this:

enter image description here

But the actual rendering completely ignores any displacement (and perhaps the roughness map as well):

enter image description here

What am I missing? Please feel free to ask any other details you may need, I don't know which other settings are relevant.

For completeness my final goal is to make this cylinder to appear as it was made in felt.

EDIT

As I wrote in the comment and after the kind answer of Hani Tiby I dont' have the displacement option under Settings:

  • $\begingroup$ You need 1) to be in Cycles 2) to have enough topology to displace 3) to unwrap your object correctly 4) in the Material panel > Settings > Surface > Displacement, choose Displacement Only $\endgroup$

  • $\begingroup$ @moonboots so far I'm stuck at point 1) since each option tells me "No compatible GPUs found for Cycles". But following a tutorial I made it, I saw a real displacement. Doing it by myself from scratch does not work. Surely I'm missing something else. $\endgroup$

  • $\begingroup$ Point 2) and 3) I don't know how to be sure they are ok $\endgroup$

I think I found an easier solution:

then I added a particle:

The result is quite good as first try, even without a decent GPU.

  • $\begingroup$ ok but it would be interesting to find why it didn't work, hard too guess without the file ;) $\endgroup$

Change the Material settings as shown. You may also need to subdivide the mesh. add Subdivision modifier and set it to simple.
