Blend Modes

NOTE: Not all blend modes work in D3D.

BLEND_NORMAL

Normal alpha blending (the default blend mode).

BLEND_ADD

Additive blending.

BLEND_SUBTRACT

Subtractive blending. Equivalent to destination = destination - source

BLEND_MODULATE

BLEND_COPY_SRC

No blending (replace mode). Equivalent to destination = source

BLEND_ALPHA_MASK

Alpha mask. Useful for changing alpha at the end of an ActorFrameTexture draw.

BLEND_ALPHA_KNOCK_OUT

Alpha knockout. Inverse of BLEND_ALPHA_MASK. Useful for changing alpha at the end of an ActorFrameTexture draw.

BLEND_ALPHA_MULTIPLY

Multiply blend based on alpha.

BLEND_WEIGHTED_MULTIPLY

Equivalent to destination = 2*(destination*source): 0.5 has no effect, lower darkens, greater lightens the result.

BLEND_INVERT_DEST

Inverted blending. Equivalent to destination = source - destination

BLEND_NO_EFFECT

Does not draw color. Equivalent to destination = destination. Useful for depth masking.
