This is a first version and still has a couple of things undefined or unimplemented, such as external objects casting shadows on or within volumes, however volume->solid shadows are going ok. http://mke3.net/blender/devel/rendering/volumetrics/shadows_test_02.mov http://mke3.net/blender/devel/rendering/volumetrics/vol_test_shad3.blend As with other transparent raytraced shadows in Blender ,in order to make it work, you must enable 'TraShad' on the material *receiving* the shadow. It would be nice to make this a bit easier to use, since there's not much chance you want a volume material to be casting solid shadows, but that's a bigger issue in the renderer outside this scope. The volume shadows are working from the same physical basis of absorption, and support coloured absorption: http://mke3.net/blender/devel/rendering/volumetrics/vol_shad_absorption.png They also work properly with multi-sampled (i.e. QMC) soft shadows: http://mke3.net/blender/devel/rendering/volumetrics/vol_shad_sharp.png http://mke3.net/blender/devel/rendering/volumetrics/vol_shad_soft.png And by popular request the test file: http://mke3.net/blender/devel/rendering/volumetrics/vol_test_shad_clouds.blend
