This pack needs to be run on top of the built in "Programmer Art" Pack and has some features that require Optifine. 

This pack includes a large list of small improvements to the base game without making it easier or changing the feel of the game. In that note, I have changed some of the newer textures to bring them more in line with the "Programmer Art Style" (Without doing a full remake of all of them, like some other projects out there. A example change:  changing the "Bucket of Powdered Snow" to use the 1.13 bucket texture). I decided to included the updated Glass textures though as I believe they are a huge improvement to the originals.

Check out my Programmer Art Redstone Tweaks if you enjoy this style of improvements.

If you prefer the updated Nether textures you can install my Updated Nether Textures pack.
