The Bloom effect doesn’t work in the Android build either. I tried other post-processing effects like Chromatic Aberration and Lens Distortion and they work fine.

It seems to be related to HDR colours. I checked my URP asset and the HDR toggle is on.

I’m using:

  • Unity 2022.3.30
  • Leia SDK 3.2.5
