@snowfall0988 We looked into this issue a bit. It turns out that in 3.4.0 Time Sculpting requires the designation of a target composition for it to work. Plus, Templater now no longer “sculpts” any other composition outside of the target comp. This means that the target and any pre-comp layers within that target get “sculpted”.

Can you please confirm that you have a target composition selected and let us know if the time sculpting works for that particular composition in your project?

Learn more about setting a target comp within your project in this support article. It’s best practice to wrap a composition’s name within double braces {{ }} to designate your project’s target.

Looking forward to learning more about your setup!
