Actually it''s not a problem with the tutorial itself, but when I try to run the included .exe no shadowing appears. I''m using an ATI 7500 Mobility and it works on my old GeForce2 Ultra. Shadowing with the stencil buffer also works in several games for me, but this tutorial doesn''t. I''ve tried playing with the hardware and screen settings, but no dice. Does anyone know what kind hardware issues could cause me to have this problem? Thanks in advance if you have any ideas.
