Unlike Maya’s many attribute sample approaches of the Sampler Info utility nodes, aiFacingRatio only has one job: To determine which direction an object’s normals points in space at any given time. The two-tone colors can also be created with a sampler info node and some ramp settings as well as any shader you want on top of it all for extra flair or depth perception – even if they don’t have Fresnel Falloff built in like Maya does by default since its been around way longer ago than either ARNOLD itself has been released back when Maxon had first started releasing their own renderer named “Maya”.Īrnold has a unique facing ratio node just for this purpose.
No more need to use the oldest of rendering engines, Mental Ray! In this tutorial we will learn how using Arnold’s new material tab can give an old but trusty effect. 3D Splanchnic Shows How to Make a Fresnel Effect in Arnold Using the Facing Ratio Node.
