Issues with packaging for android

So i’m packaging for Samsung Galaxy s5 version 5.0 lollipop and get several issues:

  1. After it’s configured itself to Android and deployed the game, the visualization in the Unreal Engine itself decreases in quality and becomes slightly pixelted. Lightmap in some objects seem to lose resolution.

  2. On the Unreal Engine, too, a material on the Hebrew letters appears heavily triangulated instead of smooth. See pictures.

the following occur in the Samsung Device

  1. In the scene there is a gate and two sides of a tall door. They operate as independent objects. On the Samsung device, all of the gate instead of the letters on the left do not show. The front and back of the door on the right is not showing, too. Only its edge is visible.

  2. A material I use in the scene does not show. The log output gives a warning that that mip value cannot be computed and that it must be absolute. Reconfiguring the material so all textures use absolute mip values and playing with the values did not solve this issue.

  3. a square column I use in the scene, and bears the material from 4), fails to appear properly. It seems to be replaced by a sort of triangle.

  4. some textures flicker a lot when the actor moves. See the wall picture.

Has anyone else met these issues and managed to resolve them? Any help will be greatly appreciated!alt textalt text

Hey 00shahaf,

You posted several issues here and while they may potentially be related we prefer to have them as separate posts so users have an easier time finding the specific problem they are having. That being said I plan to work on issue Number 2 in this post. We can move on to the others later.

It looks like your UVs are a bit messed up on the hebrew text meshes. If you would like you can upload the Hebrew text and I can take a look at it for you. If you are worried about privacy you can send me a message over the forums here: https://forums.unrealengine.com/member.php?484739-Ed-Burgess

Hi Ed!
Yeah, it was indeed a uv issue. I’ve fixed it. Still haven’t figured out how to fix the mesh and material issues, though

Okay cool, Let’s work with issue number 4 next since that is probably the root of some of your other problems. Would you mind making a new post and put the link here?

In that post I will need a picture of the material graph, you could also click mobile stats at the top to see if it triggers any error messages.

I will also need to know what device you are testing on specifically.

Just another note, it looks like you have several textures that aren’t displaying properly on mobile.

Once that is done we can continue.

here you go:

and your guess was spot on! turning on the mobile stats revealed it had a problem with a node connected to world offset.
