Allows to configure a colors along path lines by using gradient, for example along the trunk, branches or leaves.

Blend mode

Use the drop-down list to choose how the color of this setting interact with those in overlying colors. For more information see Blend Modes.

Weight %

Sets a weight for this colors. It's like a transparency, when mixed with the color from previous Vertex color nodes. The right connector allows to connect the Curve node to control the weight value along the path lines.

Gradient

Allows to configure the gradient colors along path line. The effect of the gradient moves from down (start point) to up (end point).
By default, two flags appear along the left edge of the gradient. Each flag controls a color. The gradient can have any number of flags.
The user can add new flags, drag and change color for existing flags. To add a new flag, left-click on the color field. To change the color, double-click on the flag. The start and end flags cannot be moved. To remove the flag drag it outside up or down of the gradient.
