I am making a new system based on what you people just have told me :P. It works fine so far (currently it does render a 2D image of the shadow to a texture). Now one little problem will be letting the game know which geometry polies to copy, lol. It gotta have to figure out using pivots and collisions where the shadow will land. Then the problem letting it know which of the vertexes around that area it have to copy.
