Garry's Mod
Scene Builder
Why aren't their windows?
It's not a big concern, and this mod is amazing. I think the work being done on it is great, and it still holds heaps of potential.

But still, there is yet to be windows. Having nice outside views make a scene more alive, and allows for background work and etc. for more elaborate scenes and such. Thank you for addressing, and for viewing my concern. Keep it going :)
