jerome Posted February 9, 2016 Share Posted February 9, 2016 yep sideOrientation works only at mesh creation time because it sets the underlying mesh geometry actually. example : DOUBLESIDE will build facets both sides (front/back or internal/external), so twice more vertices than for a single sided mesh BACKSIDE will invert all the normals and change the order of each facet (clockwise/counterclockwise) vertices, so this is a (slightly) different geometry than a mesh sided FRONTSIDE. Unless to rebuild the mesh from scratch, I'm afraid there's no easy way to reorganize the internal geometry on air. c75 1 Quote Link to comment Share on other sites More sharing options...
