Why is trim paths not working on my after effects?

[Karltugan]

My after effects trim pahts is not working. Can you give me advice on how to fix it? Thank you

Thanks for writing in, Karltugan.

I don't see the Start or End values changing under Trim Paths. You need at least 2 keyframes with different values. For example, the first keyframe of the Start parameter is at 0, and the next one is at 100.

Let me know if it helps.

Thanks,
Nishu
