Hello
Only sugestion:

• some broken glases (for horror themed buildings example. :) )
• connected textures for glass blocks .. looks better

Will investigate connected vanilla glass

@Drullkus I know there is a way to do a connected texture for vanilla glass since Optifine has a setting that does just that.

@vagaprime Optifine is a hack, it probably replaces the rendering code for glass completely. Not an option.

True.
