Trying to activate a post process [Inside Blueprint] when pawn is touching it and deactivating it when is not

[anonymous_user_0e3d41b3]

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 :

But it doesn’t work. Any suggestions on how I do it?

Hi!

Postprocess is automatic activated when camera inside volume. If you have in scene more than one postprocess volume, then each volume activate its own postprocess. When volumes is overlapped, Postprocess will be overridden accordingly Priority.

PostProcessVolume_Unbound in Unbound mode for Global effect and set scene color to Blue.

PostProcessVolume_1 set scene color to Red

PostProcessVolume_2 set scene color to Gree

You can adjust Blend Radius for needed length of transition between posprosesses.

Just place PP Volume with UnderWater effect under water surface and you get this effect. This is video tutorial about underwater effect:

I appreciate your answer, but this is an endless runner, so the post process is inside blueprints, that is why I am asking this. Do you have any suggestions?

You can create Actor blueprint with PostProcess component. And dynamically spawn it in needed place.
