The Gradient effect lets you create a transition of colour or alpha values between two areas of colours. You can create a linear or radial gradient. Use two points to indicate where those two coloured areas are. You can then move these points to create the transition.
The Gradient node covers the entire camera frame and beyond. You do not need to scale it up or down. It will automatically cover an infinite zone. You simply need to connect it behind your scene's elements. You can connect it in front of some elements you want to cover. By default, the Gradient has a Z ordering value of 0. When you select the Gradient node, the Camera view displays yellow triangles to indicate that it's selected.
Use the Gradient property editor to modify the values of the gradient and the position of its output.
Controlling the Gradient in the Camera View
If you want to control the gradient's orientation and points position in the Camera view, you can use the Control command to display the points and move them.
- In the Tools toolbar, select the Transform tool.
- In the Node view, select the Gradient node.
- From the top menu, select View > Show > Control.
- In the Camera view, click the Gradient's points and move them.
|Gradient Type||Lets you select a linear or radial gradient.|
|Point 1, Point 1||These sections control the values of the first point (point 0) and the second point (point 1) in the gradient.|
|Red, Green, Blue, Alpha||
The colour and alpha values of the corresponding point. You can also click the colour swatch to open the Colour Picker window and select a new colour. These colours can be animated over time if the value parameter is attached to a function curve. Default values: 0,0,0 and 255, 255, 255.
|(x) Axis||Sets the X coordinate for the corresponding point.|
|(z) Axis||Sets the Y coordinate for the corresponding point.|
|Offset Z||Enter the front-back position of the Gradient layer in 3D space. You can verify this value in the Top view.|
|Depth||Determines the composition order when the Z value of two elements is the same.|
