Black rendering artifacts

Hello,

I’m developing for android and some devices have this artifact/visual glitch on the skysphere.

Although it looks like it is in screenspace but it is only visible on the skysphere, not the meshes, nor the UI.

When looking up in the world, it is clear that the artifact is “globe” shaped, hence I think it is related to the skysphere.

The devices I can test physically do not have this issue.

Currently two devices exhibited this: Nokia 1 (on Google Play Console) and Galaxy A7(friend).

What could be the cause?

Edit:

I tested Nokia 1 again on Firebase and this time all of the meshes were black as well.

After hours of toggling various stuff in project settings, packaging and deploying, I have finally found the issue.

Project Settings > Engine > General
Settings > Settings > Near Clip Plane

I had set this variable to 1 at the start of the project because I didn’t want the camera to clip through anything ever.
Turns out some devices doesn’t support(?) smaller values.

After setting it to 3 and restarting the engine solved the issue. Default was 10.
