[uservoice]: user separate arrays for color and opacity mapping
See this
It would be great to set the opacity by a certain data value or set an alpha blending respectively. E.g. you have a 3D object with a discrete density distribution. The density is illustrated by color. Every density value was determined with a certain accuracy. Now it would be great to illustrate cells with good accuracy opaque and cells will fade more and more by increasing errors.
