Since my first attempt at stencil shadows sucked http://www.opengl.org/discussion_boards/ubb/smile.gif, could someone please explain the steps needed to create stencil shadows in a scene, please http://www.opengl.org/discussion_boards/ubb/smile.gif

Thanks!

Yeah this board has lots of post about shadow volumes. The latest one is called "carmack's reversed vs unreversed." Goodluck on your next attempt on shadow volumes, they can really be difficult.
