hi

is there a way that i can see an animation
in a sop opengl via (op i only get the first frame

thanks

Use to grab the animation.

o man thank you did the trick

Ohh lol, I was about to suggest some contraption with a time-changed callback that clears the opengl cache... seams a more reasonable approach!

The $F is needed because op: reference doesn't add the COP time dependency on the SOP. By putting $F in the expression, the SOP becomes time dependent itself. You can also specify a specific frame in the square brackets if you ever needed that.
