but why did i download a 1,4 mb file just to open it and click on a button which opens a url for the download link for the actual file?

it's like making a gallery demo that requires you to download a strange video codec, only to run that one program and never ever use the codec again

edit: i tested your alpha level, it looks quite good. but i think you're using shader right? they never work properly with my graphics card:(
but i could see the trees and the grass and the terrain and some stone floating in the air
