Elggetto Posted May 28, 2022 Share Posted May 28, 2022 Hello, I'm trying to transfer the normals from a stretched sphere, to a spiral around it, then sweep it using the ribbon shape. It looks like the normals are transfered no problem, but then when I sweep, it doesn't look right. It's either stretched, on an weird angle, or noisy (kind of like a mountain modifier). I think the problem lies in the up direction. I tried Y axis, normal, custom attribute that is the cross between the normal and the tangentu... It always look weird, especially on the ends. What am I doing wrong? Thanks! 2022-05-27_HelpNormals.hipnc Quote Link to comment Share on other sites More sharing options...
Aizatulin Posted May 28, 2022 Share Posted May 28, 2022 (edited) Hi, use the normal of the geometry as up direction (up) for the curve and tangent of the curve as curve normal (N). 2022-05-27_HelpNormals_mod.hipnc Edited May 28, 2022 by Aizatulin 1 Quote Link to comment Share on other sites More sharing options...
