Still trying to figure this out...

I think it would just be easier to switch the mod around two having two separate buildings, window and reinforced window, which each are "stuffed" to use any of the same materials that walls can (wood, stone, metal).

The XML to make that is easy. The hard part is getting the textures working, as they would be part material-dependent and part static, which is why I think this hasn't already been implemented.

Although there are several buildings in the game already that act like this. Crafting benches like the Tailor Bench and Stonecutting Table for instance. Though, quickly testing with the tailor bench reveals that using a light material like silver compared to a dark material like uranium produces different shades of the red and green thread depicted on the bench. So if the same texturing method as this was used for the windows, the glass itself would change shade depending on the colour of the wall it's based on. Hmm...

Isn't the over-wall cooler and vent from Replace Things is a better example because it does this effect simply with a transparent .png?

I don't know ♥♥♥♥♥♥♥♥♥ about coding though.

There are ways to do compatible wooded/stuff type walls, ill put it on my to-do.
@Sally Cyborg If you do create the wooden wall version, please send it to me, it would make my job easier in making it stuff compatible.

Also, glassworks is an ancestor to this mod. Long story short, I became the author of that mod and integrated it with my ceiling light mod long long ago. After many different iterations and additions, we got to this point.

There's a mod called Clutter "Window Stuff" I used before, if you need reference. Hope this info helps.

Im going to need a link to it then. Searching for that in the workshop is bring up nothing useful
