JJ FX Posted August 22, 2020 Share Posted August 22, 2020 (edited) Hi, So when you have a curve and use Polyextrude SOP by default it uses prim/edge normals. So I've been thinking, maybe edge normals are precomputed already (you know, like normals in openGL even tho you don't have them as an attibute but you need them to draw properly in the viewport and render)? Or maybe it's just Polyextrude SOP that is computing that. Do you think I can somehow access the edge normals? I can recreate them myself, but maybe that would be futail, reinventing the wheel.

animatrix Posted August 22, 2020 Share Posted August 22, 2020 Hi, I think PolyExtrude SOP is using the same code as PolyFrame SOP to compute the normals for curves. So if you use the Bitangent attribute from PolyFrame SOP, it should match the default extrusion result of PolyExtrude SOP. Quote Link to comment Share on other sites More sharing options...
