"Post Process Volume" equivalent

Hello,

I was looking for a “postprocessvolume” equivalent, like in unreal engine, to change compositors settings gradually depending on the position of the player around an area3D. I found this post from two years ago :

It seems like it didn’t exist at the time, and I found nothing about it from the person who said they were working on it. Is there something that exists now for this specific use case?

Not specifically (AFAIK), but you could use an area box with signals for body entered/exited and filter for the player, then just blend or tween the environment settings … probably two area boxes to enable a hysterisis or blend zone.
