This page provides information on the Bercon Grad texture in V-Ray for Blender.
Overview
The Bercon maps were originally developed by Jerry Ylilammi ( http://www.ylilammi.com/2013/09/berconmaps/ ) as open-source plug-ins for 3ds Max. Source code ported to V-Ray Standalone by Chaos Software Ltd.

Node
Uvwgen – The uvw generator for the texture.
Texture Map – An input slot for the texture map.
Curve Input – If a curve is used, the gradient value is taken from the texture.
Parameters
Alpha From Intensity – Specifies where to take the alpha from.
Bitmap alpha – This is the default setting. With this option selected, V-Ray renders the material the same on both sides.
Color intensity/luminance – Renders the back side of polygons as invisible for the camera.
Force opaque – Renders the back side of polygons as invisible to all rays, except shadow rays.
Compatibility with – Select the compatibility type from Max or Maya.
Gradient type – Specifies the gradient type from the following: 1D linear, 2D radial, 2D rectangle, 2D diagonal, 2D Pong, 2D Spiral, 2D Sweep, 2D tartan, 3D Spherical and 3D Box.
H – Specifies the height of the texture sector.
Interpolation – Specifies how to interpolate between textures. You can choose between linear, smooth, solid nearest, solid left and solid right.
Invert – Enable to invert the color of the texture.
Invert Alpha – Enable to invert the texture alpha. Please note, that the Invert option has to be enabled, otherwise only the color is inverted.
Jitter – The amount of random placement variation.
Noise Amount – The distortion noise amount.
Noise Levels –
Noise Size – The size of the noise distortion.
Noise Smooth –
Noise Threshold High – The high threshold for the noise amount.
Noise Threshold Low – The low threshold for the noise amount.
Noise Type – Select the noise type between Regular, Turbulence and Fractal.
Normal Function – Perpendicular, Towards, Fresnel.
Normal Type –
Placement Type – Select how to place the texture.
Whole texture is valid
Crop
Place
Positions – Specify the position of the given colors.
Tile U/V – Enable to choose between a horizontal or vertical tiling.
Type – Select the type of the placement: Particle size, Particle speed, Particle age, Random, Map, Light, Distance, Normal and UVW.
U – U coordinate of the texture sector.
UV noise phase – Specifies the UV noise phase.
Use Curve Input – If enabled, the gradient value is taken from this texture.
UV noise amount – Specifies the UV noise amount.
Animate UV noise – If enabled, the noise is animated. Use the UV noise phase to animate the noise.
UV noise levels – Specifies the UV noise iterations.
UV noise on – Enables the noise.
UV noise size – Specifies the UV noise size.
U/W – Specifies the U/W coordinates of the texture.
