Angle Blend | V-Ray for Blender material

by Hachin

V-Ray for Blender blends V-capabilities Ray’s with the simplicity of the blender core package. This post provides information about the Angle Blend material in V-Ray for Blender. 

V-ray for Blender

V-Ray for Blender combines the power of V-Ray with the accessibility of the blender core software. Blender and V-Ray for Blender are free, open-source products licensed under the GNU General Public License. To render with V-Ray in Blender you need V-Ray Standalone which is part of a V-Ray Render Node license. 

Angle Blend

Overview | Angle Blend

The Angle Blend material allows you to blend two materials together. The view direction and surface normal determine the blend angle. V-Ray can determine the blended outcome using a variety of blend functions. It can be used to make complicated materials such as vehicle paints, velvet, and pearl, among other things.

UI Path

||Node Editor|| > Add > Material > Angle Blend

Node

Material – An output slot for the material.

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.

Parameters

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.

Start Angle – Specifies the angle in which the blend will begin.

Stop Angle – Specifies the angle in which the blend will end.
