Material Problems (Black areas)

Hello community,

we’re having some problems with our materials in the main map. The main map is older than the others and was converted several times because of new Unreal Engine versions.

As you can see in the images, the meshes have black areas WHEN RUNNING THE GAME IN STANDALONE MODE. In the last image you can see a screenshot of the meshes in the UE4 preview.

Yours sincerely

Are you using baked lighting for those?

Maybe there’s a problem with the material itself, it is possible that some setting needs to be updated since you changed the engine version several times. The other thing that comes to my mind is that there might be a problem with the second UV channel aka the lightmap, hence the question of the baked lighting.

Hey Rekenq,

thanks for the quick reply. You brought us to the idea of creating a new map and copying these models into it with the same lights.
If the error is still there, there must be an error with the map because it is the only map that was updated several times because of new UE4 versions. The other maps were not updated.

Best regards,

Hey Rekenq,

we just copied a part of the map into a new map. The dark spots are no longer there, so there must be a problem with the map.

Do you know how to easily copy every object of a map into a new map? Just mark, copy and paste?

Best regards,

We solved the problem. This was not a mistake related to the lighting. The texture streaming was somehow faulty in standalone mode and in the packaged game. We re-initialized it with the command “r.Streaming.PoolSize 2000”.
