Is it possible to control the postprocess in the volume using a Boolean in the character bp?

Hi I’m kinda new to postprocessing in unreal, so far so good, I’ve set up a couple of postprocessing materials, now one out of these materials is what I want as the base postprocess, as the games launches so does the post process, then I want to be able to control the rest of these materials using a Boolean in the character bp, take for instance if I’m sprinting, the base postprocess and the sprinting postprocess should blend, but for now all I could set is one material into the volume, if anyone can help, it’ll be much appreciated​:smiling_face_with_tear::palms_up_together:t3:

Hey!

Could you please show how your setting up your logic in the blueprint please?

I’m not on my system currently, but if you mean controlling the postprocess in the volume, I used a timer in the character bp, on key press it sets the postprocess to true and on key press again, it reverses it, giving the illusion that it’s false
