  1. Hey all, I'm using houdini 15.5 and I'm trying to expose edges (in a manner similar to vray curvature/ inverted ao- https://docs.chaosgroup.com/download/attachments/12085592/VRayCurvatureHero.png?version=4&modificationDate=1487005362000&api=v2), the manual says "If the negated normal is connected, will find exposed edges. @parameters" so I took global variables, took the P plugged it into the P, took the N and added negate node (also I tried multiply constant with -1 instead) and plugged it into nN, the bias direction is 0, 0, 0, and still all I'm seeing is occlusion dirt, same as with default settings. I know that there's a 'curvature' VOP, but it yields some weird results for me, so I would like to try the dirt instead and see if it's different, so please help:)
  2. Hi, Is there a way to limit the scope of the Dirt Mask VOP to primitives? I am basically using a dirt mask to give a wear look to the fabric and set the scope to scope:self. But the problem is that when I create a dynamic simulation the dirt mask includes all primitives inside the object, as you can see in the image.
