Alpha shadows?

Can anybody tell me how to do alpha shadows in the BGE? :smiley:

You can make it only with the new blender version, the 2.5 and need GLSL suport, there is a mod that was released sometime ago but is 2.48 version only, you have to wait for the new blender verision come up to have a good alpha shadow setup.

However that mod is Windows only. Which may be what you have, maybe not.
