NewTek HyperVoxels 2.0 Manual page 33

If you drag on the Scale Keys quick drag button, you will scale all keys in the gradient bar.
The Copy Key button (or c key) copies the value/color of the current key to a memory buffer. The Paste Key (or v key) button pastes
the buffer into the current key.
Use the Load Gradient and Save Gradient buttons to load and save the gradient bar keys as a file. The Copy Gradient button copies
the keys to a memory buffer. The Paste Gradient pastes the buffer into the current key. Note that this will overwrite any existing keys.
Clicking OK closes the panel and saves any settings. Cancel forgets any changes made to the panel. Remove Gradient will turn this
option off for the parameter.

Let's do a quick exercise to give you a better understanding of how gradients work.
1. Set up a basic Null object HyperVoxels Scene:
• Add a Null object
• Add the HyperVoxel_Particles displacement map plug-in (Objects panel)
• In the Effects panel, add the HyperVoxels and HyperVoxels_Doubler plug-ins
• Activate Enable HyperVoxels (HyperVoxel Options panel)
• Select the Null object from the Object pop-up menu and then click the Activate button
2. Click on the Color P button (Surface - Basic tab).
3. Change the Input Parameter to Incident angle and set the Mouse mode to Add.
We will be changing the surface's color based on the angle of the surface relative to the camera. A surface that faces directly at
the camera will have a 0 angle and a surface facing directly up, down, left, or right would have a 90 angle. Got it? Notice that
the Start and End values are automatically set at 0 and 90 for you.
By default, you have a single keyframe at 0 degrees. It is set to pure white.
4. Now, click your mouse pointer in the middle of the gradient bar to create a key there.
5. Next, click the Color Selector button.
6. In the color dialog that appears, change the color to RGB 255, 0, 0 and close it.
Your gradient bar should now go from white to red.
