}
Expand description

How to treat alpha values when blending colors.

Variants

Multiply

The RGB components of the color are multiplied by the alpha component before blending with the target.

This is the default behaviour.

Premultiplied

The RGB components of the color are not multiplied by the alpha component before blending with the target.

For this mode to work correctly, you must have multiplied the RGB components of the colour by the alpha component at some previous point in time (e.g. in your code, or in your asset pipeline).
