Lightning Problems when too many objects are in a level

Hello community,

We are having problems with our meshes when we debug the game as a Standalone Game.
When we play it in the editor, these ugly shadows don’t appear.

We tried to copy parts of our level into another level and built the lights. Then everythin was ok. But when we copied the rest of the level into the new level, the problems occured again. (About 10.000 Meshes)

Does anybody know how to fix it?

Thanks in advance!

Yours sincerely,

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”.
