Chaos - remove broken/destroyed parts

Good morning,
I’m planning to make a game with big scenes of physical destruction.
I want to use chaos which works quite well.
However, with this numerous destructions, I want to gradually remove the debris/broken pieces/fractured pieces so that the game remains playable.
I know this topic has been discussed a few times over the last year or so, but it seems that with version 5.3.1, some options have disappeared.
I use the FS_SleepDisable_Generic. I tried sleep, or kill, and nothing worked.
So yes, the pieces are stopped/deactivated, but it remains “physically/geometrically” still present, and this makes the scene heavier for nothing.

There is that, but it doesn’t work a priori: all the pieces that arrive in FS_SleepDisable_Generic remain present all the time.

On version 5.0, there were additional functions: Look “removal”


It comes from this very interesting video : [https://www.youtube.com/watch?v=0bIx4vThZcQ&ab_channel=BuildGamesWithJon]

This function was very relevant, and even necessary. Does anyone know how to reactivate this function in BP, or find another solution?
I tried kill/remove, … but it doesn’t work for geometry collections.
THANKS.
