I am trying to apply the caustic FX to an animatiom Im playing with.
The caustics work great for the stills, but when I try to render the animation I get a weird problem with the caustics.
I use the basic seting from the tutorial, with 4 cristal colored boxes 1 light and all inside one box.
The colored caustics seem to move like crazy, even when everything is not moving.
if you have time, you could see the movie here:
