Where's the glass blocks?

Playing with the new forge and I can’t seem to find the glass blocks that were in the preview video. They were just plain blocks made of glass, no framing or other pieces attached. Anyone know what category they’re under?

Anyone? This is driving me insane.

Didn’t see any but when you find them let me know if any are breakable please.

Go to Structure > Accents, then scroll wayyyyyyy down (use the right trigger to jump down by section) until you see “Glass.”

wtf no glass blocks

Make a glass block then.

You’re not referring to the invisible barriers are you? They are blocks, no framing, and can be viewed as glass block while in forge mode, however when in actual gameplay you can’t see anything.
