Glass

I like windows and bullding pathways, both elevated and underwater. I'd like waterproof windows I dont care if they have to be constructed from normal windows and steel, actually that would make sense. But i'd like for it to exist, so I can create underwater tubes or even aquariums later.

if you clear out the water source blocks with building blocks, you can then remove the building blocks and use other blocks to make an enclosure. I have a few underwater "aquarium" type rooms that work fine, but the glass blocks won't remove the water source. It seems like only the regular building block will do that, so use those first.

Nah I want glass ceiling and walls underwater. That are waterproof. and I dont mind if they have to be a higher tier, so long as they exist
