captainbuckfish 0 Posted September 6, 2017 Hi, 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, Duncan bumpTex.hiplc Share this post Link to post Share on other sites
