When vectorizing a child comp and then lengthen this comp, the new part of the comp is not shown in the parent comp until I restart AE.
Thanks for filing this bug report.
Can you please provide more detailed steps to reproduce the problem? I presume that by “vectorizing a child comp” you mean you’re enabling the Continuously Rasterize switch for the pre-comp layer, but I don’t want to assume. I also need clarification on which comp you’re referring to by “lengthen this comp”.
Perhaps you could provide us with a sample project in the “before” state and instructions or a screen recording of what to do that causes the problem. Post a link to your files here, or if you prefer not to post publicly you can send it to firstname.lastname@example.org. (If you send to that address: A) Do not send .zip files, they will be blocked; renaming to .thisisazipfile is OK. B) Post a comment here when you have sent the email. I need to manually check that inbox.)
