How can I use "Turbulent Noise" as a displacement?

[Masoud]

Hi;

I would like to use "Turbulent Noise" as a displacement texture in my material, but it doesn't works properly, why?

My goal is to achieving a displacement output like this link:

Thanks for helping.

I have only Houdini 16

use this and have fun

Aah, I just had a hard time dealing with this problem this weekend.

Found some solutions but overcomplicated IMO.
With just a principled shader at Mat level is so simple, by the way no need to unwrap or rest sop in the sphere object... but I can't get it to work in a material builder. trying all sort of tranform space but no way.
But thank to sreltak network I guess why. Need to retry.

PS don't forget to frequently stop and restart mantra (not only refresh) when you do your tests.

Hi, Fred! Open the Displace_F.hip, I don`t see any displacement in a viewport. What I am doing wrong?

Visible in Mantra only.

hello flcc,

when you collaps to material network you have to re-assign the material to the sphere. it's still looking for the principledshader. but the displacment bound on the properties-node seems not working right. I deleted the channel and set it to 10 and it worked.

Ah, I completely misunderstood the original Masoud question, I thought the goal was to see the material displacement in the viewport. I have no idea why, sorry

But I am still interested if ist possible.

@primzahl
I try what you say, but I get this. Trying to crank up the bound value don't change anything.
Maybe there's something I didn't understand.

@kiryha
Look at the Houdini VOPs // Illume Webinar with Jeff Wagner. In the exemple files, there is one called vops_grunge_up_diffuse.hip where there is a material with displace visible in the viewport. Why it's work and mine not, I really have no idea.

Thank you but this seems very complicated...

Thank you, but I want to use displacement in material builder...

If you find the solution, let us know.
Really curious to unserstand why it don't work in material builder !

hello, I added the properties node to your network and now the displacment works. Kai Stavginski form sidefx explains the workflow in one of his shader-tutorials, but I have forgotten in which one - I belive it is the costum shader ...

Ahh Thank you very much.

So in materialBuilder context the displacementBound of the principled Shader don't work and you must use a mantra propertie !
it's a bit sneaky IMO.
I could never have found it on my own. And yet I searched. This should be indicated in bold and red in the displacement section of the doc.

 

Thanks again
