So I have a river where the character has a post process under water and no post process when out of water. For that I have created a trigger in and out of water. For the trigger under water I did :
Hey,
what about using a post process volume? by default it’s configured to behave like what you want: Activate when entering on it and deactivating when exiting.
Yep so you just place the post process volume inside the water and when they enter the water/ post process volume it will turn on, and when they leave it, it will turn off. You are taking something very simple and trying to make it more complicated.
