Sequence camera sync has stopped working

Hi all,
every so often the “Sequence camera sync” stops working.

I have an animation consisting of 2 different cameras, both nodes I inserted inside SEQUENCER and for some reason scrubbing the timeline does not switch the cameras anymore.

Any ideas?

how often does this happen, Karol? is it reproducible after certain actions or it just occurs out of no where? is it possible for you to screenshot how your sequencer looks with the two camera tracks?

also, were you able to update to the latest or is this happening on 2023.1.0? does your colleague have similar issues on 2023.2.1?

Hi @Simplychenable It seems to be happening randomly because I haven’t touch the camera in this project since 1 week and suddenly they don’t switch anymore. Opening the scene on another computer shows the same problem.

I just updated to 2023.2.1, although it happens to me every so often since version 2021.

Thanks!

i can’t seem to repro on my end with a basic scene. is it possible for you to save select the two cameras and sequencer information as a new USD? once you’ve done that, see if the issue persists on your end with the new file. if it does, perhaps you can upload it for Richard and/or others to test.

also, can you confirm whether the cameras are on the root layer or separate a layer?

That sounds like a bug. Anyway you can capture a video of the bug and send your USD scene over ? You can DM me the scene privately for testing

@Richard3D was there any resolution to this bug? I can reproduce this reliably on two specific USDs. Others work fine.

We cannot reproduce this error. What version of USD Composer are you using? The latest, kit 106.5?

I’m using 2023.2.5-prod.3 with kit 105.1.2.

Let me know if you’d like me to provide a USD privately for reproduction.

Thanks, but that will not be necessary, just yet Please, if you could update to the latest version of USD composer. You are still on kit 105.2. You are several versions behind. Then, if your error is still occurring, we can file a ticket from there.

Here is my one list cheat sheet for quick build

  1. Download “git” from Git - Downloads
  2. Download "git Large File Storage from https://git-lfs.com/
  3. Start a windows command console by using running “cmd” from the Windows Start menu
  4. Navigate to the root of c: or d: drive. Example "cd"
  5. Copy and run “git clone GitHub - NVIDIA-Omniverse/kit-app-template: Omniverse Kit App Template”
  6. run “cd kit-app-template”
  7. run “repo template new”
  8. run “repo build”
  9. run “repo launch -d”
