Displacement Texture

[AlexanderThePilgrim]

Hi,

I'm not sure if this is an issue or if I'm just using the wrong workflow but I have a displacement texture that I am using that works fine with Karma but when I switch to RPR then all displacement goes away. I've tried several different shader setups from using the principled to using the RPR combine with an RPR uber and a displace texture and output node and I can't seem to figure out how to get texture displacement working, am I just going about this wrong? Thanks in advance

Hi, can you share a sample hip?

[AlexanderThePilgrim]

Yes, here is two ways I tried to accomplish it (the one setup obviously doesn't work in Karma as it uses RPR nodes)

• rubber_toy material does not work because Houdini sets the displacement terminal only for karma:
  
  (as you can see outputs:displacement does not have any bound node)

• pighead material does not work because you are using VEX based node (RPR just can't work with it):
  

I've updated rubber_toy material, please check Displacement.zip

Thank you, that helps a lot. I figured it was something about how I was setting it up but I couldn't find answers for it anywhere

Have you seen this tut https://www.sidefx.com/tutorials/3rd-party-rendering-in-solaris/? Varo explained such things quite well

No I haven't, thank you!
