Hi
there’s two way to get pieces to be “removed” after a while
- remove on break
- remove on sleep
Remove on break if the one that give you more fine control
You can define per piece how much time will pass before the piece start be removed
Go to the Fracture Editor
Go to Utilities tool section
Click on Set removal-on-break parameters icon
then select the pieces you need and set the parameters according to what you need and apply them
(See screenshot below)
The remove on sleep parameters is directly on the asset properties
I hope this helps
