One of the servo skulls I shaded and textured for the game Warhammer 40,000 The Horus Heresy: Betrayal at Calth.
Model by Rodney Brett.
About 179,000 tris depending on what parts are swapped out. The headgear and tentacle ends have a few different variants.
Graph for the swappable servo kit that allows for a custom decal alpha that can be rotated or toggled on and off with color input, fresnel on the lenses, adjustable emissive, and an RBG packed mask for Metallic, Gloss, and AO.
