i finally got the shadow shader code working... seems as if there's some issues with the ambient shader and the shadow shader...
i had to use based cpu shadows, and substitued the code that caled for the ambient shader effect to dbSetObjectAmbience()...
anyways, here's the code... just substitue it in the source file for the project you already have working...
