Hi!  
I have a problem with export from ae file. I trying to make a blob liquid animation. My animation is a shape with nulls from patchs. I animate them by position:  
freq = 1;  
amp = 50;  
loopTime = 5;  
t = time % loopTime;  
wiggle1 = wiggle(freq, amp, 1, 0.5, t);  
wiggle2 = wiggle(freq, amp, 1, 0.5, t - loopTime);  
linear(t, 0, loopTime, wiggle1, wiggle2)  
All look great, so I make a new comp from selection and than I’m trying to export as lottie. But then m blob is not smooth - animation is freaking crazy!

My friend made the same animation for me, it work great even as lottie. But when I try to export his animation is crazy too!

Where am i making a mistake? Please help me because one more try and I’m going crazy too!

Thx!

I don’t think lottie supports expressions. I think you need to convert them to keyframes.

Hi @dorota You’ll need to covert the expression to keyframes. You can do at the expression. Right click and find the “convert to keyframes” and it should work after that.
