Hi, I noticed that Planar Reflection doesn’t work for Android ES 3.1 and iOS Preview Rendering Level after upgrading from UE 5.0.3 to UE 5.1.0, but Shader Model 5 works fine. I tried an empty project and it had the same issue.
Actually I found another issue in UE 5.1.0: UE 5.1.0 Exclude editor content when cooking not working, there is significant increase of the package size on Windows, it was 333MB using UE 5.0.3, but now 634MB in UE 5.1.0 regardless selecting “Exclude editor content when cooking” or not.
To reproduce:
Create an empty project
Enable “Support global clip plane for Planar Reflections” in Project Settings
I have been up for forever trying to fix this brother
In the World Outliner, Select The Planar Reflections Actor
Look for:
“Angle from Plane Fade End”
And Adjust
Ensure Mobile HDR is on
Ensure Mobile Planar Reflections Isn’t On Usual
In command prompt, enter “r.Mobile.PixelProjectedReflectionQuality 1”
(((max is 3) 0-3) Four Settings))

UE 5.2.0 and UE 4.27.2 work fine. In material Base Color 1, Metallic 1, Roughness 0. Just tick “Planar Reflections”, no need to tick “High Quality Reflections”.
Maybe I messed up with the material settings by rapidly optimizing the performance. Originally my project was created in UE 5 Early Access, then upgraded to UE 5.1 → UE 5.2.
Actually the problem is not related to engine versions, it is from Material → Details → Translucency → Lighting Mode → Surface ForwardShading. My water material is Dafault Lit and Translucent, “Lighting Mode: Surface TranslucencyVolume” doesn’t work for Android ES 3.1 and iOS, has to be “Surface ForwardShading”, but that’s the most expensive one.
