Brake Assembly update
I tried to produce a truly cross platform asset that would work with any 3D package and renderer. This model is available on my CGTrader store (https://www.cgtrader.com/3d-models/vehicle/part/brake-assembly-for-racing-car) and is comes with setups for Maya (Vray & Arnold), Max & Modo as well as a full set of 8K textures for both PBR Metal/rough and Spec/gloss workflows. Everything is mapped in the 0-1 UV space. Textured in Substance Painter and Designer. Rendering in Vray Next Beta for Maya using GPU (also in Max with same setup). This uses the new Metalness option in the VrayMtl so the PBR metal/rough maps exported directly from Painter work.
EDIT: This is now available on my artstation Store. https://www.artstation.com/bmcaff/store
