DescentBB

What it says on the can. I tried opening the level in the editor to see, but I didn't see any custom textures displayed. So how were the see-through dark glass panes done? That's an amazing effect.

There's a feature in Descent's engine but unused by Parallax called "cloaked walls" I think. It essentially removes the texture from the wall and makes it partially transparent like a cloaked bot.

Yeah, that was the one. It's the only way to do partial transparency in standard D2 levels. XL, as we all know, supports alpha, but that wasn't an option for TEW.

I think it renders the wall the same way it renders a cloaked ship or robot...
but you'd have to look at the code to be sure.

Pretty damn sweet.

I tried using that once, but had to switch to a forcefield bridge when I couldn't tell it was there (even in 80-something percent cloak)
You can do this with a 100% cloak to get a solid black wall, or 0% cloak to get a completely transparent, yet not shoot-through-able, wall.
