Octane Gradient Map Node
The Octane Gradient Map node produces a gradient blend between color values. It can accept a texture input (such as input from the Octane Falloff Node) to determine how the gradient is mapped to the surface, provided the projection for the texture input is defined.
The Gradient node is not equivalent to the LightWave 3d gradient; for that, the Gradient Rampand Gradient Ramp 2 Nodes are a better choice.
In the Octane Gradient node, any two color values will mix with each other if you do not use the input channel group ( available in Complex mode, discussed below), as in the mix shader or cosine mix.
The Octane Gradient node is used more often for color and value remapping.
Input Parameters
The node has two (2) inputs:
Octane Texture - This input can be an Image Texture, Gray Scale input, RGB Color, Procedural Texture (including the new Falloff texture)
Gradient - This input is the new ACGradient node which has a new UI to set-up gradients.
Output Parameters
The node has a single color (vector) output.
Octane Texture - This color output can be plugged into the texture inputs of any Octane material node.
Node Parameters
The node allows you to choose the interpolation type for the gradient to be applied. Either Physical or Perceptual interpolation.
Usage
As example of the usage of the node is shown below.
A simple default grayscale gradient plugged into the Gradient input pin, with a falloff node pluigged into the Octane Texture input pin. The output is fed to the color pin input on an Octane Diffuse Material.
This will give an output that can be seen in the IPR as shown below:
