  2. Slope based noise

    Hi all, We are working on a custom Houdini shader and want to add a layer of slope based dirt on top of the textures. Right now we are importing the global variable 'N' into our Material network and are calculating the dot product between this 'N' and a constant vector of 0, 1, 0. We then use this dot product as a bias value for a colormix node, as long as the dot product is positive we add dirt, else no dirt is added. (see screenshot 3) This kind of works but when rotating the camera (see screenshots 1 and 2) the added dirt moves as well. It is allways in yUp as seen from the local camera. Any Ideas how to fix this? Thanks Cyrill

  4. Hi all, Houdini noob here We are trying to create a Digital asset which should include a couple of lights, a camera and a Mantra node. We did create a new subnet which includes the lights and the camera, however we don't know how to add the Mantra node. How can we achieve this? Thank you for your help Regards, Cyrill
