NiAlphaPropertyGetSourceBlendFunction

This is a command from NifSE.

Syntax

(short:blendFunc) NiAlphaPropertyGetBlendFunction short:nifID short:blockID
(short:blendFunc) NiAlphaPropGetBlendFunc short:nifID short:blockID

Returns the integer ID of the blend function used by the NiAlphaProperty specified by blockID. The possible values and their meanings are indicated below.

Returns -1 if the function fails for any reason.

The default value of blockID, 0, indicates the NIF's root, a NiNode. NiNode blocks are not derived from NiAlphaProperty, so this function will always require an explicit blockID.

Blend Functions

• SRC_COLOR = 2
• ONE_MINUS_SRC_COLOR = 3
• DST_COLOR = 4
• ONE_MINUS_DST_COLOR = 5
• SRC_ALPHA = 6
• ONE_MINUS_SRC_ALPHA = 7
• DST_ALPHA = 8
• ONE_MINUS_DST_ALPHA = 9
• SRC_ALPHA_SATURATE = 10
