This page provides information on the V-Ray Gradient Texture.
Gradient is a texture map that can easily create and edit gradients useful in many different situations.
The Switch To Advanced Settings () toggle activates the Advance Settings mode, giving you access to a larger number of settings for modification of the Bitmap texture.
Any texture can be replaced via the Replace With New Texture () button, which activates when you select the texture to be replaced. If the texture is an instance, all copies are changed as well.
Preset – Applies a gradient preset. When the gradient is manually changed, the Custom preset is automatically selected.
Red/ Green/ Blue
Type – Controls the direction and shape of the gradient ramp. Changing the Type does not affect the color and position of the control points.
V – A gradient changing along the V direction.
U – A gradient changing along the U direction.
Diagonal – A gradient with a diagonal transition.
Radial – A gradient with a radial transition.
Circular – A gradient with a circular transition.
Box – A gradient with a box radial transition.
UV – A gradient changing along both U and V directions.
Four Corner – A gradient that transitions linearly between colors assigned to each corner.
Tartan – Creates a gradient with a plaid pattern.
Interpolation – Changes the color interpolation method. Changing the option changes the color transition curve between the control points.
None – Disables the transition.
Linear – Values are linearly interpolated in RGB color space.
Exponential Up – Values are exponentially interpolated from left to right, each color dominating the area between it and the next one.
Exponential Down – Values are exponentially interpolated from right to left, each color dominating the area between it and the previous one.
Smooth – Values are interpolated along a bell curve, each color dominating the region around it before blending to the next color
Bump – Values are interpolated along a sin curve, based on luminosity values.
Spike – Each color dominates only its immediate area, falling off shortly after.
Left-click on the Gradient bar to add additional color points. Right-click on any color point to remove it.
Color – The color of the currently selected control point.
Position – The float position of the currently selected control point.
Amount – Controls the strength of the noise texture distortion.
Frequency – Controls the noise frequency. Smaller values make the noise pattern appear bigger and vice versa.
Type – Controls how the texture is positioned on the geometry.
2D (UV Channel) – The texture uses the object UV coordinates.
Environment – This mode is applicable if the map is connected to an Environment slot or a Dome light.
Mapping Source – The texture uses an external UV placement source.
2D (UV Channel)
UV Channel/Set – Specifies the index of the mapping channel data to use. A value of 1 takes the first available channel.
Repeat U/V – Determines how many times the texture is repeated in the 0 to 1 UV square.
Lock U/V Repeat – Locks the U/V Repeat.
Offset U/V – Controls the texture offset in the U and V direction.
Rotate – Rotates the texture (in degrees).
Tile U/V – Tiles the texture in the U and V direction. If the option is disabled, the Default texture color is used outside the 0 to 1 UV square. Default color is found in Parameters > Color Manipulation.
Mirror U/V – Mirrors the texture in the U and V direction separately. The option cuts the texture in the half flipping one side vertically or horizontally. This can be used to avoid seams in-between non-tileable repeated textures.
Mapping – Specifies the type and shape of the texture.
Rotate H – Rotates the environment sphere horizontally.
Flip H – Flips the environment sphere horizontally.
Rotate V – Rotates the environment sphere vertically.
Flip V – Flips the environment sphere vertically. This option is active only in Spherical Mapping.
Ground – Enables ground projection of the texture.
Position X/Y/Z – Offsets the ground projection along the X/Y/Z axis.
Radius – Specifies a projection radius. Can be used to control the scale of the projection.
2d Transformation – see 2D (UV channel) parameters.
UV Placement Source – External UV placement source to be used for the texture placement.
