Atom Posted May 11, 2016 Share Posted May 11, 2016 Hi All, I thought I knew how to do this but when I tried I got stuck. I want to copy cones to the center of every face/primitive on a hemisphere. I thought Copy could do this natively but I guess not. I also want to be able to invert the Normals so I can FLIP some of the cones to face in and some out. I tried using @N *=-1; inside a Attribute Wrangle but nothing happened, the copies seem immune to the normals. How do I align to face normals? ap_align_to_primitives.hipnc Quote Link to comment Share on other sites More sharing options...
mestela Posted May 11, 2016 Share Posted May 11, 2016 set prim normals divide->compute dual (this puts a point where the prims were, and a prim where the points were, its like the inverse shape) @N *= -1 for the cones you want to flip copy sop done. me_align_to_primitives.hipnc Quote Link to comment Share on other sites More sharing options...

mestela Posted May 11, 2016 Share Posted May 11, 2016 Ha, more like I have an amazing bunch of co-workers who collectively know everything about everything, but they rarely post here, so I get to take all the credit. Quote Link to comment Share on other sites More sharing options...
