Bump map from Cd value to Principled shader. Bump/Normal workflow

Recommended Posts


Struggling with materials (as always) in Houdini. I am using attributes to overide material values which works fine for roughness etc but bump values I dont understand.

I want to use the principled shader but is there a way to take cd values from the mesh and assign as a bump using the principled shader?

I used the material Builder to get some displacement onto the mesh but dont understand the correct workflow for this. So many options and nodes related to Bump/Normal/Displacement. Also transform space from object to camera etc and displacement bounds...

So much to learn and figure out so currently watching the custom shading masterclass but if I cant figure out the basics its hard to get to the advanced level.

I have attached a .hip with the issue I have. Can somebody give so advice on the most common and reliable method of assigning bump/displacement in shaders from attributes.

Many Thanks,
