I'm trying to figure out how this thing works. I've downloaded the example from your website and used it for my animation. It works fine, but only if the keyframe containing the UILoader is positioned at frame 1 in the timeline. If I move to any other position, CasparCG won't play the animation at all. And also, another condition is that flash template containing the UILoader has to be in video layer 20 or above to be played.
