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?

Can you post an image?? I'm sure that there is a function (keys combination) to orient normals, but at the moment i don't remeber it. Try to search in the archived messages... Hope this help TOXE

OK, here is a picture: 1. Create a u-shaped mushroom in spline modeler 2. Convert to polygons, remove "closing" of the shape (see white arrows) 3. Add hairs: They appear on the trunk (green arrow) and on the inside of the top shape (red arrow).

As suggested by Eric Winemiller from DCG, simply go in the vertex modeler, select Edit->Return shape (I have a French version, I don't know the exact label in English) and there you are: Hairs on the trunk and on the outside of the top shape. (See picture.)

Thanks to you all.
