The elevator has the glass in the model already. But for the panels, you only have the arms and the frame and put the (usually metal) platform brush onto it. But I think there were glassy ones, just can't remember in which levels. The frozen glass texture looks ugly on it. There is a coop_airlock texture that looks very similar but the resolution is poor. Any ideas?

So I don't know what to tell you. You could always extract the texture for that model and make your own material that can be applied to brushes, and use that on your arm prop walkway.

As I said, my problem is not making a moving panel. I have it working with a normal metal brush. I was looking for a way to make it see-through, like the panels in the Glados fight scene. The panels they use there are made specifically for that level. They're not using the arm64x64 model I'm using. The only glass textures I could find look ugly on an arm. Anyway, I'll just keep using metal ones if there is no better solution.

There's a smaller glass arm that's used for the coop doors, would that suffice?

I can't recal the name exactly, but it looks like it's built on a piston (and for some reason has, off all things,walking animations...lol)

I want to know, how to make those 64x64 glass-panels, seen in coop
