I just do basic things , no fancy stuff :
I created a cop network inside /obj
inside the cop network, I added a 'fractalnoise' node. I can see the noise image in the scene view.
I added a previewmaterial node in the cop net.
Connect the output from fractalnoise to the 'height' of the previewmaterial.
Now in the scene view , I can't see the fractal or texture , it's just white.
I follow this video and the grid should look displaced by the fractal like this one :

what is wrong ?
can't view previewmaterial in cop network

What is your height scale set on the preview materail.
For me, using all the default settings I actually have to reduce that scale(initially set to one) to bring down the displacement to more pleasing levels.
Everything using default value - no parameter changes at all. I think I should see visible spikes. But I only got simply flat surface.
Btw , I'm using osx version of Houdini 20.5.278. Maybe a bug ?

metaclay2Perhaps it is a bug for osx...I'm using windows
osx version
Post your hip...I'll open the file using windows and if I don't get your 'error', then definitely it's a bug for osx.( could be related to the viewport as I see a long discussion about that for mac on the forums here).
Otherwise it's possible you may have made a parameter change and forgot about it?

Confirmed it's a bug on OSX version - running on macbookpro M1 max.
It works fine on my windows (tested just now)
Thanks man.

I wouldn't say this is a bug, SideFX described it in the documentation. New COP requires vulkan viewport, but it is not implemented on macos. I also faced this problem
https://www.sidefx.com/docs/houdini/news/20_5/viewport.html [www.sidefx.com]
- Native display of COP nodes in the Scene Viewer.
- The Vulkan viewport isn’t supported on macOS. MacOS uses the OpenGL viewport renderer.
