Random Color diagnostic shader

Shades the surface with random colors. Adjacent surfaces display with different colors, making it easier to see the patch structure, and how the patches align.

The Random color mode shades the surfaces with random colors. As a result, adjacent surfaces show up in different colors, making it easier to see the patch structure, and how the patches align with one another.

Random Color Options

You can control the qualities of the shading with the Random Color options. For the most part, they are the same as the options documented for the Multi Color icon. However, instead of a Color slider, there is a Color saturation slider.

Color Saturation

This slider sets the common saturation, or the “vividness”, of the color.

Specularity

Change the size and intensity of highlights on the surface.

Transparency

Set the transparency of the shaded surfaces, from 0.0 (totally opaque) to 1.0 (totally transparent).

Light Intensity

Set the brightness of the light source.

Link Light to Camera

When this option is checked on (default) the light source for the shading comes from the camera (like a headlight), so that the highlights move over the model as you tumble around it.

Checking off this option un-links the light source from the camera and locks it to its current position, so the highlights remain stationary as you tumble. It also displays two sliders and a manipulator that let you rotate the light around the model.

Note: The center of rotation is calculated at the moment Link Light to Camera is checked off. It corresponds to the tumble center used when tumbling with Alt + Shift + left mouse button (with Tumble Center set to World Point in View > World Move Camera >Tumble). Setting a point-of-interest (POI) on the geometry or doing a View > Look At modifies the tumble center, hence the center of rotation.

Light Azimuth

Azimuth values range from -180 degrees to 180 degrees and rotate the light horizontally.

Light Elevation

Elevation values range from -90 to 90 degrees and rotate the light vertically.
