Short description of error
When some object with animation is inside a collection and this collection is excluded from View Layer

the animation is not evaluated when the collection is included back to the View Layer.
There is a workaround - need to change the animation frame.
Note that this behavior doesn't affect render - it's just for the 3D viewport.

Exact steps for others to reproduce the error


To reproduce the issue please follow the next steps:

  • open the attached blend file

  • note where the Cube is placed
  • exclude test collection from View Layer
  • set animation frame to 30 or another
  • include test collection back to View Layer

Expected result: The cube position should be calculated depending on the related animation.

Actual result: The cube appears in the same place as it was before excluding the containing collection.

Best regards and thank you!
