Please note, Angle Blend material is a legacy material plugin that can no longer be created since V-Ray version 3.60.
Mtl One – Sets the material to be used on the area perpendicular to the view direction.
Mtl Two – Sets the Material to be used on the area parallel to the view direction.
Start Angle – Specifies the angle in which the blend will begin.
Stop Angle – Specifies the angle in which the blend will end.
Blend Function – Specifies the specific method for V-Ray to calculate the blended result. For more information, please see Blend Function Diagrams below.
Linear – A straight linear progression from material 1 to material 2.
Normal Distribution – Starts approximately evenly blended between material 1 and 2 and then gradually transitions to material 2.
Sigmoid – A slow curve that eases out of material 1 with the Start Angle before smoothing out in the middle, and then easing into material 2 at the end with the Stop Angle.
Gompertz – A curve similar to Sigmoid, but slightly faster at reaching a point where the materials are blended.
Cube Root – A smooth curve blending from material 1 to material 2 that rapidly jumps around the middle of Start and Stop angles and then returns to a smooth curve.
Cubic – Rapid progression from material 1 to material 2 that slows down briefly around the middle of Start and Stop angles before resuming fast progression toward material 2.
Cubic Polynominal – A smoother cubic shape with a longer hold in the center of the blend than Cubic
Flip view direction – When enabled, reverses the direction of the blend.
Can be Overridden – When enabled, the material will be overridden when Override Color is enabled in the Global Switches.
