This page contains information about the V-Ray Gradient Ramp Texture.
Overview
Gradient Ramp is a texture map that can easily create and edit gradients useful in many different situations.
Settings
Type – Specifies the type of gradient ramp to create:
Four corner – A gradient that transitions linearly between colors assigned to each corner.
Box – A gradient with a box radial transition.
Diagonal – A gradient with a diagonal transition.
Linear – A gradient with a simple linear transition.
Mapped – Specifies a map to use as a gradient.
Normal – A gradient based on surface normals and the camera.
Pong – A gradient with a diagonal transition that repeats in the middle.
Radial – A gradient with a radial transition.
Spiral – A gradient with a circular transition.
Sweep – A gradient with a linear sweep transition.
Tartan – Creates a gradient with a plaid pattern.
Position – Allows the user to specify a Gradient Position.
Gradient Position – Specifies the position of color in the gradient that is returned when Type is set to Position.
Gradient Noise
Type – Specifies how the colors are randomly distributed across the gradient.
Regular – A plain noise with a non-fractal function.
Fractal – A fractal algorithm to generate the noise.
Turbulence – A turbulence based noise type is used.
Amount – How much noise is introduced.
Size – The scale of the noise.
Phase – Controls the speed of the procedural's noise.
Low Threshold – Sets the low threshold.
High Threshold – Sets the high threshold.
Smooth – The amount of smoothing of the noise.
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. 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 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. 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.Color Tweaks

UV Noise
Type – Specifies the mapping type. 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. Type – Specifies the type of projection mapping to use from the following:None Planar Projection Camera – Selects a camera. Projection Camera (LOP) – Same as Projection Camera parameter but for use in the LOP context. Fit Fill – Specifies how the projection is fitted. Vertical – Fitted vertically. Fit Type – Specifies the type of fitting to use: None U / V Angle – Specifies the U / V mapping angle. Film Gate W / H – Specifies the width / height of the film gate. Hide Backface – Determines whether to project on back faces of polygons. Hide Occluded – Determines whether to project on occluded points when using the Perspective Type. Object Space – When enabled, the projection is applied in the object space of the currently shaded geometry. Use Reference Points – Uses reference mesh/rest inputs for projection calculations. Mapping Type – Specifies the type and shape of the texture from the following: Spherical, Angular, Cubic, Mirror Ball, Screen, Spherical (3ds Max), Cylindrical (3ds Max), Shrink Wrap (3ds Max), and Spherical (V-Ray). Horizontal Flip – Flips the environment horizontally. Vertical Flip – Flips the environment vertically. Horizontal Rotation – Specifies the horizontal rotation (left and right). Vertical Rotation – Specifies the vertical rotation (up and down). Texture Rotation – Specifies the texture rotation. Wrap U – If true, U values outside the [0;1] range wrap back to [0;1]. You can choose between the No Wrapping, Wrap and Mirror Tile options. Wrap V – If true, V values outside the [0;1] range wrap back to [0;1]. You can choose between the No Wrapping, Wrap and Mirror Tile options. Wrap X – If true, X values outside the [0;1] range wrap back to [0;1]. You can choose between the No Wrapping, Wrap and Mirror Tile options. Crop U / V / W – Enables or disables cropping in the U / V / W direction. DUVW Scale – Specifies an additional scale factor for the texture derivatives. Ground – Enables ground projection of the texture. Ground Radius – When Ground is enabled, this specifies the radius of the ground. Ground Position – When Ground is enabled, this specifies the coordinates for the ground.Mapping
