Whenever I try to play a map I created in the editor, the blocks I create show up as complete black! I also move through static meshes and can't use the S and E key to move. Worst of all, whenever I look somewhere the static mesh that I saw originally looks like windows on a computer do sometimes when you move them, they sort of copy themselves where ever they move!
Does anyone have any idea what's wrong?
