Create custom spot light decay
An intensity curve or an expression can be used to control decay. You can also create a custom brightness decay rate using an intensity curve. You can edit curves in the Expression or Graph editors. For more information about the Expression or Graph editors, search the Maya Help.
Create custom spot light color decay
You can create a custom color decay rate using a set of color curves (a red curve, a green curve, and a blue curve).
To create a custom color decay
Maya creates a RedCurve node, a GreenCurve node, and a BlueCurve node and connects them to the Color attribute.
Edit custom intensity and color decay
You can edit intensity curves or a set of color curves either in the Attribute Editor or in the Graph Editor. Intensity or color curves display as a table of values in the Attribute Editor.
