This is the first render of a work in progress and the lighting and casting of shadows is a pain. Could somebody please tell me why the edges of the shadows are zig-zagged? And since I'm using a square at 90degree angle for a wall why are the shadows so high? There is one infinite light casting shadows with a map of 1024. I can't make it go any higher. With a spotlight the jagged edges were worse. Please, somebody shed some light on this.
