Some of the effects in Studio 14 Ultimate have a help manual that magically appears when you click on the question mark in the upper left corner of the effects control.  Unfortunately, many do not.  In particular, I'm looking for help with "real shadows" from the RTFX 2 section.  I can't quite grasp how to use the effect.  Anyone know where I can find instructions for that and the other effects that don't seem to have manuals within the program?
