Hello,
I´ve noticed that matte objects are not visible on saved attenuation maps, so that correct shadow casting on geometry is impossible.
As you can see on the attached composition (composite.jpg), the shadows from the particle sphere are casted on objects in front of it too,
because these matte objects are not excluded correctly in the attenuation map (attenuation_map.jpg).
I´ve attached the testscene too, please take a look at it. I´m using the latest Krakatoa version 1.5.2 Beta 2 and 3dsmax 2009 (german).
Thanks
