hellbydante Posted February 7, 2023 Share Posted February 7, 2023 Hi everyone, I was following a tutorial for an embroidery animation and I was trying to see how it could be adapted to run normal to a curved surface instead. I was able to get away with using point deform to manipulate the animation on a wavy surface. I am unsure how to multiply the normal inside the point VOP to get the spline animating normal to the curved surface (shown below). Not sure if adding normals using the point SOP before the ray SOP helps. I've attached the .hip file for reference. Would be immensely grateful for any help or guidance. Thanks!

animatrix Posted February 7, 2023 Share Posted February 7, 2023 Hi, You can do this using the Displace Along Normal VOP. Just make sure to compute point normals for the cloth before you perform the Ray operation, then you can use N directly on the strands: Quote Link to comment Share on other sites More sharing options...
