Texturing for Minecraft Mods

Last several weeks I have been working on designing new content for Minecraft mods. My brother Vincent is working on Java programming for embedding new content in the game. In the screenshot below I developed textures for new weapons, characters and environments.

I have been using Linux Mint OS and Gimp for developing the above textures. The process of developing textures is a bit difficult and follows typical UV mapping approach. Basically, the process involves working with flat materials that are later applied to 3D objects.
