Neekozo Posted May 30, 2019 Share Posted May 30, 2019 (edited) Hi amazing houdini people! This is driving me insane, ive been using polyframe to add normal directions to points on a curve when i scatter onto it. But when i use the same technique on a circle i always have to fuse points and then im left with this. Driving me insane, how do i fix the circle normals??

Dweeble Posted May 30, 2019 Share Posted May 30, 2019 I have this often. It's usually point 0. In this scenario I'd probably set my normals relative to the circle's center (Polyframe Style set to Primitive Centroid), or "@N=getbbox_center(0)-@P;" in a wrangle. In looping but not circular geometry I manually set point 0's attributes in a wrangle (like averaging its neighbors attributes, or manually calculating the tangent from the geometry's last point). If that doesn't work I resample to a gazillion points and interpolate. If that's not an option I clip half the geometry off and mirror it. If that's not an option I delete my graph and abandon the project. Hope you get a cleaner answer, I've been wondering whether there's an easy, universal solution.
