Android Exposure not working (4.27)

Hi there!

Due to some bugs in 4.26 (UMG has weird behavior) I upgraded my project to UE4.27.
All went well, but the Manual Exposure stopped working on Android.

This did work in 4.26, and I really need this to work.

Is there something I can change to make this work again?

I’m using the oculus-branch, which has an optimized mobile tonemapper, but that only makes the scene darker, but still overblown.

I’m thinking of using the launcher version (or source build) of 4.27, but I need exposure to work without hdr.

Attached are the look in 4.26 (mobile and pc) and the overblown look in 4.27(only on mobile)
Kind regards,

Marcel

So as a fix (not ideal, but it works),
Commenting out this line makes it possible to use exposure on mobile (without hdr):
