The blending rules when rendering a Tile/Material.
Values
None
Out = 1 * Src + 0 * Dst
Alpha
Out = SrcA * Src + (1 - SrcA) * Dst
Add
Out = SrcA * Src + 1 * Dst
AlphaAdd
Out = Src + (1 - SrcA) * Dst
SoftAdd
Out = (1 - Dst) * Src + 1 * Dst
Multiply
Out = Dst * Src + 0 * Dst
AlphaMultiply
Out = Dst * Src + (1 - SrcA) * Dst
Erase
Out = 0 * Src + (1 - Srb) * Dst
Screen
Out = 1 * Src + (1 - Srb) * Dst
Sub
Out = 1 * Dst - SrcA * Src
Max
The output color is the max of the source and dest colors.
The blend parameters Src and Dst are ignored for this equation.
Out = MAX( Src, Dst )
Min
The output color is the min of the source and dest colors.
The blend parameters Src and Dst are ignored for this equation.
Out = MAX( Src, Dst )
