Pause everything including materials except some actors

Hello

i would like to pause everything in game, including materials effect, and pause game is not an option.

I tried GlobalTimeDilation but while the game paused i want to change a some post process continuously for example
exposure effect, changing this will cuz exposure to go up but never down until i restore to GlobalTimeDilation to it’s default value, i tried also to change CustomTimeDilation to be 1/GlobalTimeDilation for actor, but looks useless.

Another try i did using GetAllActorsOfClass (class=Actor) and loop through them and put CustomTimeDilation, now everything is paused and post process works perfect including exposure effect, BUT materials won’t stop (like water for example).

updating material to accept “Timer” from blueprint is not an option as i got many materials want to stop not little.

anyone guys ?

me to …
