Chrome Environment VEX node
Simulates a chrome material defined solely by an environment map and a normal direction.
This operator simulates a chrome material defined solely by an environment map and a normal direction. Unlike other chrome solutions, this one does not use a reflection model, thus avoiding the costs of ray-tracing.
This type of chrome shader was popular in the 1980’s. Despite its obvious limitations, it remains useful today thanks to its speed and simplicity.
If the Surface Normal (N) input is not connected, the global variable by the same name will be used instead. Typically, you will not link “N” unless you want to displace the surface before performing the chrome calculations. Bump Noise is one of many candidates for surface displacement. If you do need “N” itself, you will find it in the Global Variables operator.
