In the past I asked for the ability of disabling the shadow casted by a material. It would be very useful to use a cylindrical or spherical background image and avoiding it stopping the light coming from the daylight system. On the opposite side, it would be also very usefull to allow making a material unvisible while still casting a shadow : When you use a cut out person or a tree, mapped on a billboard with alpha, if the direction of light is pointing to the side of the billboard, the character or tree will cast a very narrow shadow, or even no shadow at all. Usually in such situation we use an unvisible object used as "shadow caster" to get a realistic shadow effect depite the fact that the object is flat.I really hope that we'll see these features in a future release !
