PBR has officially been added to every block in the game!
Unfortunately, I've temporarily removed all specularity maps (this is what makes some textures shiny or reflective), as it was very inconsistent. This however is something I'd like to slowly re-implement in the future.
For the time being though, enjoy a screenshot dump of some of the textures you'll be able to get your hands on in tomorrow's update :)
(Tomorrow's update will also include the ender chest, and lambda better grass support from my previous post)
