Hmm, I haven't seen that before.
How are you exporting to mp4 in AE - Render Queue or sending to AME?
Do you do a fresh export each time, or keep restarting the same pre-existing export task?
Asking around more and it seems like this may be a bug on AE's end. Is it possible to share here or DM me your full zipped project via a shared link on Google Drive, Dropbox, or Creative Cloud to take a closer look?
I usually just drag the CH scene over to my AE composition. Its very strange because the updates from CH will change within AE but when I export and play the Mp4 it will still have the original CH scene (doesn't export the edits I've made). I'm not sure how I can send that to you to show you.
Hmm weird. Not sure what's going on, we'll look into it deeper.
For now, I'd suggest the same thing I did in this thread: try the more old school PNG + WAV export instead: Using Character Animator with After Effects
If you can post a screen-recording going through the steps showing the buggy behavior it would help us track it down. Thanks!
I'm having the same problem. No matter what I do the CH file doesn't update in AE. Tried deleting and re-importing and some elements change but draggable arms seem to not change. Odd.
Mine actually updates in AE but when I export into MP4 those CH edits don't show...yet they are still in the comp in AE its beyond frustrating
Two workarounds I've started using are add current scene to new scene in CH (although this will not allow you to make rigging edits to the scene/characters) in the new scene. Plus you have to redo any keying in AE
Export AE comp to Premiere and export as Mp4.
I'll make a video showing this bug when i get a chance hopefully sometime this weekend.
