Projected Shadows

...possible in 3D GameStudio with the use of shaders? Not only projected on terrains but also on level geometry and entities in real time so that if a player walks under a tree or near stained glass the pattern is projected on them as well. Does anyone have a working example that I could take a look at or could someone point me in the right direction as to how I would go about setting this up?

I'd even be willing to throw down some cash for working source code and a how-to implement tutorial. Let me know, thanks in advance!

This is from the Shader Index

Awesome! I'll check it out, thanks a ton!!

I wouldnt suggest using that shader, it doesnt work so well...i made it a long time ago.

@matt: Do you have an updated version that isn't part of the Sphere engine? Or better yet, that could be easily implemented into your Sphere plug-in? (all the more reason for me to buy it) The island demo level does this to some extent with the trees casting shadows on the terrain but I'm looking for a little more control by using projection planes where I need them.

Maybe at an additional cost?
