I created this resource pack for my modpack. It has most textures for most blocks of the following mods:
- LightningCraft (also all mobs)
- ProjectE
- Nyx
It has also textures for Eerie Entities, aside from the Pumpkin Slime, for Special Mobs' Cave Spiders and Zombies and for Energetic Sheep.
This doesn't contain the base minecraft textures, as I didn't create those.
You can go to this totally coincidental-looking resource pack for the base minecraft textures.
