Hi, together with a friend of mine I´m working on a game for a project in school, but yesterday we ran into a problem. Since we live some two hours away from each other we use Dropbox to share the files. After I had finished making a box for a character, which was imported from make human, to make it walk, my friend could only see the character as Wireframe and after he changed the rig I now have the same problem. I also noticed that the screen only shows gray when I try to play the game in the game engine. Would be thankful for any suggestions on how to fix this problem.
