Cannot Change Post Process Setting in Game

Hi there, I’m trying to change scene color tint value during play but as I do this in BP nothing changes when I press B key. The event is triggered and I can get correct values when print them to screen. Any idea why this happens?

Make sure your post process volume is ‘unbound’ and that you don’t have other volumes that overwrite your’s.

I also had a problem with Post process not doing anything because I didn’t have “Mobile HDR” checked on, even tough I was on PC. Also check scalability options

My post process volume is unbound and it’s the only one in my level. “Mobile HDR” is checked on by default and scalability is set as Epic.

Hi PhoenixThrough,

  • Have you tried this in 4.11?
  • Does this occur in a clean, blank project with no additional content or is it limited to one project?
  • What steps can I take to reproduce this on my end?

  • I haven’t tried this in 4.11
  • This doesn’t occur in a clean project but does occur in a clean map of this project
  • I’m not sure how to reproduce it… I’ve tried to remove the original PPV and add a new one with default settings, or migrate this map to a clean project, neither may trigger Post Process setting changes.

Finally locate the cause… As I’m using FPS Template for this project, there’s Post Process Settings binding on my camera with blend weight set to 1. It may overwrite the settings of PPV in level map.
