How to do glass

First of all, I've read the tutorial included with the map editor, but I can't get it to work (the glass doesn't even has to be breakable, but i would be nice).

Here's what I did:

• Made the level.
• Selected the faces that should become glass.
• Detached them and named the new object %glas
• In the material editor I made a new material and called it glas
• Where it says Material#03 i changed that to zanzibar glas%-
• This points to the right folder and shader, and it works when compiling, but in sapien is shows up just being black
• It's a custom build shader, but I actually copied all the settings from the default glass shader

Someone knows how to get this to work?

Open the bitmap and uncheack unused.

Alright that fixed it:) no need anymore for this thread so I'll close it.
