Wreckingcanon decided to figure out what Krystal might have looked like if she had appeared in Star Fox 64. He worked with concept artist Alain J. and found The Regressor, a 3D modeler and rigger who specializes in making low-poly, N64-style rigs. With this information in hand, the Krystal Archive funded the development of this rig, affectionately called "Krystal 64". After complete, we also got some assistance from King-Jion to make a Blender-compatible version.
This rig features a blaster and holster, as well as a sleeveless jacket to show off Krystal's tattoos. Krystal looks pretty good in purple, I think!
As with Warfaremachine's rig, this is a completely free rig available for download, use, and remixing, just check the README for requirements. Thanks to everyone involved!
Check out the Krystal 64 page for more details, concept art, renders, animations, and the download. The rig is available in Blender, Maya, FBX, Wavefront OBJ, and COLLADA formats.
