Here's the MC Master Chief, straight out of Halo 4.
He's got two different skingroups, one for an uncracked visor, and a custom cracked visor. He uses custom cubemaps created by Hyperchaotix, and a custom lightwarp made by SedimentarySocks and Taco for his visor.
The model retains it's original rigging, but there is a rig script you can download here.
Special thanks to Cspeti for attempting to fix the messed up rigging on the fingers, and to Mustafa for completely fixing the rigging.
I do not own this model, this model is property of 343 Industries and Microsoft, and it is being used without permission.
