Shadows weren't lining up because I didn't have any vertex normals. Entities need to have correct normals in order to render both light and shadow correctly.
Original Post:
When i rotate a entity the shadows don't always line up with the edge perfectly. Not sure if the shadows are just limited or if i forgot a step. I tried changing the distance for the rendering of the shadows, but that didn't seem to change much. Any help would be greatly appreciated.
