Gunner , Driver View

[AKM74]

Hello Guys.

I need some help with a gunner and driver view. Actually with periscope (if I call it right)
I know how to simulate transparency with alpha channel.
But if you look on this picture, you will see other (main) wall behind it. But in game you can still see thru it, even if wall behind not transparent.
I don't know how they did it. I did study demo models…but still don't understand how it work.
Can someone explain it to me?

PS
I can copy and paste this part from demo. But I'm still wanted to know how they did it.

Thanks for your help.

I'm not sure if I understand the question, but I think it has to do with glass textures in OFP having certain probs.  

If you look through glass, certain objects you can see, others dissapear.    Try making just a glass box addon and test this.  I wasn't able to see things that were placed in the editor for the most part.   :-\

So, maybe they just found an object/texture that the glass worked correctly with??

(Just a shot in the dark)
