Hi William,
Go to the Amabilis site tutorials as under:-
http://www.amabilis.com/tutorials.htm#TutorialsMSTS
Scroll down to user written tutorials and you will find Ian's tutorials along with stacks more (Note that Ian's were written for earlier versions of 3D Canvas, so his instructions for setting up bitmaps and masks using Paint Shop Pro are now out of date, as 3D Canvas now allows you to use .tga files which include the masks instead of bitmap files).
