Hi all. I want a lot of planes acting like sprites (allways facing the camera). I need to do this with expessions, preferably only in the first frame of the animation (like setting an aim-constraint). how should i do this?. I don't know how to set a constraint with mel.

Can i ask why it's necessary to do this using expressions? It's very easy to just do it with aim constraints as you suggest.

cheers,

Mel is easier than creating expressions. This creates a camera and a plane (oriented up) then constrains:

camera;
polyPlane -ax 0 0 1;
aimConstraint -offset 0 90 0 camera1 pPlane1;


It wouldn't be hard to have it randomly place many planes and constrain them all to one camera. If you don't know a command in mel, like aim constraint, go through the process in maya then open the script editor. The command will be there along with the // result //.
