I can't get certain shadows to show in BGE. I have the correct lighting with the sun and hemi lamps. When I'm editing in BGE, all the shadows show like I want. But when I press p to play, all shadows still work except for one. The one that doesn't show while playing is a bunch of planes connected together, all of them with the same texture on it to make a clump of grass. When I was making it on a different layer with the same lamps, the shadow it casted worked while editing and while playing. But when I moved it to a different layer with the same lamps, the shadows only worked when editing and not when I press p to play. I have no idea why. I'm using GLSL if that matters.
