What GLES level you are using in your app? Have you tried use the other one? I know there were some weird shadow issue on GLES 3.1 in the previous version of Unreal.

Also can you try tp record those positions with this problem and try place the camera and your scene in the same spot and see if you can reproduce the issue in Unreal editor when setting preview level to the one you were using on your phone.

I'm currently using OpenGL ES2 I will try using OpenGL ES3.1. And I don't understand what you are meaning by record positions ? I have perfect shadows in the editor, no matter the orientation of the camera even in Game View mode.

Thanks for the reply by the way :D

I mean try change the editor graphics preview level to GLES 2 and see if you see the same issue in Unreal Editor.

So I tried both same results. And when I set "Settings"->"Preview Rendering Level"->"Mobile/HTML5"->"Android Preview" AND "High-End Mobile"->"Mobile OpenGLES 3.1" I have effectively no shadows. Which I don't understand because it should. My skylight is in Static with "No Cast Shadows" and one "Directionnal Light" with the following setup :

And all my models have this setup : "Movable" (of course I think) and "Receive CSM Shadows"
and this :

Do you have Mobile HDR enabled? Modulated Shadow only works when Mobile HDR is enabled, if I remembered correctly. Also your light need to be stationary.

Unfortunately yes :( I will try to have Dynamic Shadows with stationnary lights because when I put my light in stationnary I have no shadows anymore.

Have you tried using dynamic shadow? It seems modulated shadow have some bug in Unreal 4.20.

I have verified both dynamic shadow and modulated shadow works fine with ARCore in Unreal 4.20. If you still find this is a problem, feel free to reopen this bug.
