Hey esenthel, just recently i don't know what the hell i did, but i regularly use remote desktop applications so many people connect at the same time and watch, and suggest things, show me ways to do other random things that i didn't know about, many keys get pressed, ctrl stays pressed, etc. so yeah settings get messed up, The problem i am facing is that if i build the world with a player character in the world i can't see it at all, it just does not show any more, i can move with it, but the mesh just doesn't show, my system locale is korean as i play korean games, it's recently started happening. the physics load and i can run around the game world, just the mesh doesn't show at all.

These may be stupid questions-I'm not sure what kind of troubleshooting you've done, but have you double checked your object settings to make sure the mesh did not get deleted or resized accidentally? If somehow the entire mesh hasn't been somehow set to "hidden?" Or if your object type got changed accidentally (although you typically wouldn't be able to move if that were the case).

Also, is this happening in the WE play mode or in your actual client?

well, i imported a new model in and it worked, i think you may be correct, as we use drop box sometimes, when uploading it can get full and not upload the right files, because our project will end up as 4GB, it's 2GB without the map, thanks i'll try reimporting the models
