Dear all, I made a U-shaped volume (built in Spline modeller, converted to polygon modeller) and I'd like to get hairs in the outside of the shape. When I use DGC AnythingGrows (very nice tool BTW), hairs are coming on the inside of the U. Is there a way to 'invert' normals (if, as I assume, hairs are grown on the "normal" side of the polygon). What do you suggest to solve this tricky problem?
