Expand description
Defines a formula for blending two color or alpha values.
Variants
Add
Blends by adding the source and the destination together.
(srcValue * srcBlendFactor) + (dstValue * dstBlendFactor)
Subtract
Blends by subtracting the destination from the source.
(srcValue * srcBlendFactor) - (dstValue * dstBlendFactor)
ReverseSubtract
Blends by subtracting the source from the destination.
(dstValue * dstBlendFactor) - (srcValue * srcBlendFactor)
Min
Blends by picking the minimum of the source and destination.
min((srcValue * srcBlendFactor), (dstValue * dstBlendFactor))
Max
Blends by picking the maximum of the source and destination.
max((srcValue * srcBlendFactor), (dstValue * dstBlendFactor))
