Stack 'Em
A FoxLoader (ReIndev) mod that adds support for stacked (multiple) texturepacks
Texturepacks GUI
This is how the texturepack change GUI looks like after installing this mod. As you can see, it now allows to add a texturepack in list to "the stack" and move the order within the stack.
Runtime gluing!
One of the newest features of this mod is runtime (automated) gluing of textures from different texturepacks into one. This is achieved via comparing the modified textures against vanilla version and detecting "segments" of modified pixels.
CharMap menu!
Starting from 0.3.4 the mod adds a new menu accessible from texturepacks menu - CharMap. Useful for debugging font texturepacks, and for other reasons you can imagine.
Item Texture Swap
You can easily swap items' textures based on either their display name (shown here) or by metadata value. Check docs for more information, guides and examples
Armor Texture Swap
The mod now supports custom armor item's textures! Just like items' icons themselves, you can provide your armor textures based on either metadata value or display name.
