This page provides information on the V-Ray Bercon Grad Texture.
Overview
The Bercon maps were originally developed by Jerry Ylilammi (https://www.ylilammi.com/posts/2013-09-30-berconmaps) as open-source plug-ins for 3ds Max. Source code ported to V-Ray Standalone by Chaos Software Ltd.
The V-Ray Bercon Grad texture combines features of Gradient Ramp, Falloff, and Particle Age maps and expands them even further. It provides an easier control of color variations between objects and particles.

Main
Color Ramp – A gradient ramp for the Bercon Grad color.
Cam Space – Enables calculations in camera space.
Texture Map – Specifies a texture used for mapped gradient ramp.
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.
Interpolation – Specifies how to interpolate between textures. You can choose between Linear, Smooth, Solid Nearest, Solid Left, and Solid Right.
Ior – Specifies Fresnel IOR to use.
Reverse – Specifies whether to reverse the gradient.
Range Min/Range Max – Defines the range a gradient is drawn.
Range Loop – Specifies how the gradient behaves from None, Tile, Mirror, Stretch.
Use Dist – Enables the use of distortion. When a texture map is connected to this channel, it distorts the V-Ray Bercon Grad texture depending on the texture map.
Dist Str – Specifies the distortion strength. Solid colors have no effect and the more contrast in the connected texture, the more visible the distortion.
Dist Map – Specifies a distortion map.
Type – Specifies a type of placement from UVW, Normal, Distance, Light, Map, Random, Particle Age, Particle Speed, and Particle Size.
Normal Type – Specifies the falloff direction to be used by the Normal Function:
View – Uses the camera viewing direction. This is the most common selection.
Local X / Local Y / Local Z – Uses one of the object's local axes.
World X / World Y / World Z – Uses one of the world axes.
Camera X / Camera Y / Camera Z – Uses one of the camera's axes.
To Object
Object Z
Normal Function – Specifies the type of falloff:
Perpendicular – The falloff depends on whether the normal specified by the Normal Type is parallel or perpendicular to the camera.
Towards – The falloff depends on whether the normal specified by the Normal Type faces the camera towards or backwards.
Fresnel – The falloff depends on the IOR.
Use Curve Input – Specifies whether to use Bezier curves.
Color Tweaks
Default Color – Specifies a color when there are no valid uvw coordinates.
Mult – Specifies a multiplier for the texture color.
Offset – Color corrects the texture by adding the RGB color values specified here to the RGB color values in the texture.
Invert – When enabled, the resulting texture color is inverted.
Alpha Tweaks
Source – Specifies the alpha source from Alpha, Color, and Opaque.
Use – Differentiates between textures exported from different applications. You can choose between Color Intensity (3ds Max) and Color Luminance (Maya).
Mult – Specifies a multiplier for the texture alpha.
Offset – Specifies an additional offset for the texture alpha.
Invert – When enabled, the resulting texture alpha is inverted, too. If disabled, just the color is inverted.
Placement
Placement Type – Specifies the way the valid portion of the texture is applied. The options are Full, Crop, and Place.
U/V – Specifies the U/V coordinates of the valid texture sector.
W – Specifies the width of the valid texture sector.
H – Specifies the height of the valid texture sector.
Jitter – Specifies the amount of random placement variation.
Tile U – When enabled, there is horizontal tiling.
Tile V – When enabled, there is vertical tiling.
UV Noise
Enabled – Enables the UV noise.
Amount – Specifies the UV noise amount.
Levels – Specifies the UV noise iterations.
Size – Specifies the UV noise size.
Animated – When enabled, the noise is animated.
Phase – Specifies the UV noise phase.
