after effects - circular trim path I have an animated circle shape layer with trim paths applied to it and the end percent animated from 0% to 100%. But half way through the animation, the circle path seems to close itself. How can i fix this?

if the circle animation is somehow not visible here, here is the link to imgur: http://imgur.com/hRKmcb7
I can't reproduce your issue on my end, but I can offer an alternative method. Another way to create the circle example you've provided is to use a Radial Wipe effect on the shape layer:

Effect &gt; Transition &gt; Radial Wipe


Just animate transition completion from 0 to 100 percent. If your shape layer is moving, you may also need to pickwhip expression the Wipe Center parameter to your position parameter:

transform.position


I hope this helps you out. Good luck!
