my project works fine before i start the game but when i start it everything turns white. any help? thx alot in advance!

I have had problems with this too

its fine now, i did some thorough searching of the forums (searching for post instead of thread) and found that i had to add a material to each object which solved my problem, but thanks for the help anyway!
