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.

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.

UV Name – The name of the UV channel that is used.

Repeat U – Multiplier for U values.

Repeat V – Multiplier for V values.

Coverage U – U values are remapped to 1.0.

Coverage V – V values are remapped to 1.0.

Translate Frame U – Translates the frame in U direction after applying rotate_frame (and before wrap, coverage, clamp).

Translate Frame V – Translates the frame in V direction after applying rotate_frame (and before wrap, coverage, clamp).

Rotate Frame – Rotates the frame after applying UV noise.

Rotate UV – Rotates the UVs after mirroring.

Offset U – Offset added to U before mirroring (after wrap, coverage, clamp).

Offset V – Offset added to V before mirroring (after wrap, coverage, clamp).

Noise U – Noise magnitude multiplier in U direction.

Nose V – Noise magnitude multiplier in V direction.

Mirror U – When enabled, every other tile outside the [0;1] range is mirrored in U.

Mirror V – When enabled, every other tile outside the [0;1] range is mirrored in V.

Wrap U – When enabled, U values outside the [0;1] range wrap back to [0;1].

Wrap V – When enabled, V values outside the [0;1] range wrap back to [0;1].

Stagger – When enabled, tiles in the V direction add +0.5 to the U value for a 'staggering' effect.

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.
