Bad shadow in mobile Ue5

Hi developers :slight_smile:
When I change the view from Shader model 5 to Android ES 3.1, the graphics changes a lot and it may be ordinary due to the difference between the performance of Pc vs Android devices, but what is not ordinary is that the shadows disappear.

Shader 5

Android ES 3.1

Unreal Engine 5.0
Any help, please?

Hey there @anonymous_user_9dd78251! I don’t work too much on the mobile side, but could you give this fix a try and let me know how it goes?

hope this helps!

Sadly same problem


Hrmm… In your project settings, is the support movable directional lights box checked?

Actually the same problem, but I found out something that may help you to find out my problem.

when I decreased the quality settings of the editor of the windows preview the shadows disappeared, So I think there is a problem with the settings of the mobile shadow quality somehow being set to a low value.

This is the android preview I made sure that the quality is sat down to cinematic

This is the window preview with cinematic scalability

This is the windows preview with only the shadows sat down to low

I hope this could help you.

Hrm, so there is one bit of oddness with mobile scalability I’ve seen a bunch of times. I didn’t think that’d be the case for yours since there wasn’t wild distortion. Try to pop this node on your begin play and let me know if the shadows appear. (this isn’t a fix but it will point us in the correct direction for one if we’re right).

I found out finally the solution, I don’t know the explanation but it is simply by enabling Force No Precomputed Lightning
