MINOR PLAYGROUND. Vray For C4D Review. Cinema 4D Vray Materials by ~ValdesBG on deviantART. Welcome | www.vrayforc4d.com. Multi Layered BRDF Materials The best render engine is worthless if the materials doesn't behave fully correct according to natural laws of light. For physical calculation one needs a true physical Material (=BRDF). In V-Ray the BRDF Material is the heart of V-Ray, not an added effect, very fine balanced to work perfect together with GI, and all aspects of light reflection, absorption and scattering. It is multi-layered, based on true BSDF/BRDF code and brings highly realistic glossy reflections, anisotropy which can both be textured, and last not least perfect and physical based subsurface scattering (fast SSS2, refractive SSS), all at V-Ray light speed! "Choose & Use" Presets The VRAYforC4D 1.2.6 update just released brings many enhancements.
