The Painterly Pack Customizer Tool
Updated for use with Minecraft 1.8 and earlier.
The Customizer allows you to create a personalized Minecraft texture pack, by selecting from a variety of options for each texture. When you've made your selections, click 'Create my Painterly Pack' to download a fully-assembled, ready to go zip file! Simply place the zip file in your Minecraft resource packs folder using the in-game menu option, select it from the list of installed resource packs, and you're good to go! Each customized pack contains a password.txt file you can use by clicking here which lets you load that pack's chosen options directly into the customizer!
Although the Painterly Pack is provided free of charge, a great deal of time, effort and testing has gone into making it what it is today. All donations help, and are extremely appreciated!
