Perfect Leonard, thank you, you should have seen the gymnastics i was going thru to get that done. lol really appreciate it john From: Leonard Koch To: john clausing ; "softimage@listproc.autodesk.com" Sent: Monday, July 15, 2013 12:05 PM Subject: Re: Orientation of particles by curve Get the pointtangent through closest location and plug it into the Point At port of a Direction to rotation node and get the pointnormal through a closest location node and plug it into the Up Vector port of the same Direction to rotation node.

Orientation of particles by curve
Hello all, I want to emit particles (rectangles) by volume from a subdivded cube deformed along a curve. I want the emitted particles (they don't move) to be within this volume and oriented by a tangent to the curve Basically, is there a way to "get" orientation from the curve. thank you, john
