No problem, I think I’ll switch to Unity for a variety of other reasons, for the mobile Unity is the top

Thats great man.

The post processing on UMG doesn’t work on Mobile

What is your workaround for this guys ? Use a blurred texture instead ?

Sounds like you might have to resort to a plugin or modify the engine yourself from Source code.
To get bloom on split screen I had to change a 0 to a 1 in one of the source code files and compile the engine. If this is not as simple as that then you will have some C++ to learn.

Hey,

I have been investigating this issue. The blur is not working on Android even today in 2022. I have Unreal Engine version 4.27.2.

Also Epic has marked this bug as “Won’t Fix” Unreal Engine Issues and Bug Tracker (UE-65007)

You can use LowQualityFallbackBrush | Unreal Engine Documentation
as a fallback for the blur.

Blur can be enabled for android by setting “support backbuffer sampling on opengl” to true in Android settings in your project settings

This setting is greyed out - I’m using Android for the Quest3, so it’s a bit of a mystery why.

Is it solely for UMG, or does it need to be on for other MotionBlur effects, I’m trying to fake some blur with the “PreviousFrameSwitch” node.
