Gradient Interpolation Specifies the type of calculation for the intermediate
values. These affect the entire gradient.
■ Custom. Sets an individual interpolation type for each node. Under Current
Node select the interpolation type.
■ Ease In. Weighted more toward the next node than the current node.
■ Ease In Out. Weighted more toward the current node than the next node.
■ Ease Out. Weighted more toward the previous node than the next node.
■ Linear. Constant from one node to the next. (Default.)
■ Solid. No interpolation. Transitions are a sharp line.
Noise Type Displays the different methods to create the perturbations: Regular,
Fractal or Turbulence.
Noise Amount When nonzero, a random noise effect is applied to the gradient,
based on the interaction of the gradient ramp colors (and maps, if present).
The higher this value, the greater the effect. Range=0 to 1.
Noise Phase Controls the speed of the animation of the noise function. A 3D
noise function is used for the noise; the first two parameters are U and V and
the third is phase.
Noise Size Sets the scale of the noise function. Smaller values give smaller
chunks of noise.
Noise Levels Sets the number of fractal iterations or turbulence (as a
continuous function).
Noise Low Adjusts the low noise threshold. When the noise value is above
the Low threshold and below the High threshold, the dynamic range is
stretched to fill 0 to 1. This causes a smaller discontinuity at the threshold
transition and produces less potential aliasing.
Noise High Adjusts the high threshold. Range = 0 to 1.
Noise Smooth Adjusts the noise smoothness. Range = 0 to 1.
UV Scaling Specifies the horizontal and vertical scaling for procedural maps
on materials.
Rotate Rotates the map around the W axis of the UVW coordinate system.
Rotation is not available for spherical and cylindrical mapping. Use
MATERIALMAP on page 1102 to display the mapping gizmo that can rotate box,
planar, spherical and cylindrical maps.
