Glass & Glass Panes
This pack changes Glass & Glass Panes to have no shards.
If you’re using OptiFine, they will have shards when there’s a glass area with a size of 2×2 blocks or bigger.
The amount of shards are still less than vanilla though.

Tinted Glass, Stained Glass & Stained Glass Panes
These blocks will have no shards at all.
Using OptiFine, the glass will also connect.
Also the top texture of Stained Glass Panes now has a lower opacity and is a solid colour.

Other
The Beacon also has no shards.
You can now actually see Light Gray Stained Glass Panes when it’s in your inventory.

Some bugs I don’t know how to fix (only occurs with OptiFine)
Beacons when placed next to Beacons, Glass or Glass Panes look a bit weird
Glass and Glass Panes of the same type will connect and look a bit weird.

USE OPTIFINE OR THEY WILL NOT CONNECT AT ALL
