How do I make a single-paned glass window?

If i use the glass shader on a brush doesn't that make the window double-paned? I read that if you use double-paned windows it costs extra performance, so how can i use singlepaned ones? I thought of using a simple patchmesh would this be ok?

Hmm...

 

Usually you don't cover all of a brush's faces with a texture, just those that can be seen by the players. And usually a texture on a surface can be seen from only one direction. I'm going to make this more clearer.

 

Will that window be able to seen from both sides? If no then it is enough to put the glass texture on that surface which is towards the room, all the other five can be covered with system/caulk. This system/caulk will not be drawn so will not eat performance.

 

If the window can be seen from both sides then you have to cover both sides with the glass texture but the other four with system/caulk.

 

Since the texture on the inside surface of the window can be seen by looking from inside and the texture on the outside surface can be seen only from outside it is not a problem to put the glass texture onto both.

ah, that makes sense thanks.

I think you mean double sided (or single sided).

 

Double-paned glass is an actual addition you can make to your living quarters that saves you like 10-15% on your heating and cooling bills (better insulation).

 

Doubt that has much to do with mapping. Heehee.
