Why my game on mobile is soo green

Why my game on mobile is soo green?
on Anroid mobile its green and on PC its ok

on Android mobile phone:

on PC:

Probably some shaders are being downgraded for mobile.
You can run emulated android devices in editor .

This is my guess but check postprocess shader.

can you share probable post processing shader?

Do you use any postprocess shader in your project? It should be there somewhere if you are using.

Check target platform settings, and shader model you are using for this project.

Unreal 4.27 needs mobile GPUs that have ES3 (Openg GL3) support. You phone doesn’t have that, you can check your phone specification to find out what ES version has.

If you need it to work on ES2 I think you need unreal version 4.23 or even lower. never tried.

But 80% maybe more of android devices at the moment have ES3 support so don’t bother supporting older devices. You can check google, they have a page where it shows what are the devices specification world wide at the moment. I don’t have the link at hand.

yes i have how to check target platform settings and shader model?

test mobile phones is newer models
i mean MI 11, Samsung Galaxy S21 etc.
for beginning its working well without green
but after some edits its turned to green
and i don’t know which change is made it to green.
Please any suggestion?

Try to use RenderDoc to capture and identify which render pass cause the problem.

RenderDoc can launch APK and attach itself to the process.

The build configuration should be Development otherwise the DrawEvent name will be omitted.

@BoBoMX @Nawrot @dorusoftware thank you guys.
problem was my engine.(broken engine)
i packaged on different pc then it works perfectly
srry guys for wasting your time.

but i didn’t found how to fix my broken engine…

Engine is not broken, you probably changed some settings for mobile platforms.
Compare settings for engine on both computers, you will find where YOU messed it.

It’s an old post but I had this issue and searched here so maybe someone else will. The solution is to delete the Sphere Reflection Capture that will be in your map.
