Ok this is the last thing I can think of.

Try these in your startup wdl...
There are more settings in the display00.wdl in the
templates folder of GS..

even try including it in your project.


[CODE]
//----------------------------------------------------------------------
// section: Shadow

// entry: Stencil Shadow
// help: Stencil shadows 'bend' around corners, and objects cast shadows on themselves.
// id: 53
var shadow_stencil = 1;


// entry: Shadow Offset
// help: Set the distance that entity shadows are offset from the floor
// id: 12
var shadow_offset = 3;

//----------------------------------------------------------------------
// enable: Adv. Light Res?
// help: Improve light resolution
// id: 29
var d3d_lightres = 1;
[/CODE]

If that don't work I don't know what else I can think of.
Other than look at the Acknex site and download tutorials from there.

Remember, the tutorials you are doing are simple, the only teach you the basics. Better ones are available, you only need to be patient and
search.
