I downloaded the Force Field tutorial that Massassi has to offer. However, I cannot get it to work, at all. I have tried everything I can think of to do... I think I have the right surfaces for the switch and the force field surfaces. I have the template set, but it wont work! I dont know if the Geo for both surfaces should be set for 0, or 4, but either way, I cannot get the force field to work. Can someone help me?

OK, set the GEO on both sides of the adjoin to either 3 or 4, (3 if the texture is a solid color, 4 otherwise). Then, go to adjoin flags and make both sides of the adjoin transluscent, and also impassable. That's the important thing. Make sure the adjoin flag "passable" is NOT checked.
