NiAlphaPropertyGetSourceBlendFunction

This is a command from NifSE.

Syntax

(short:blendFunc) NiAlphaPropertyGetSourceBlendFunction short:nifID short:blockID
(short:blendFunc) NiAlphaPropGetSrcBlendFunc short:nifID short:blockID

Returns the integer ID of the blend function used for the source 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

The function of each value is equivalent to the OpenGL blending function of similar name.

• ONE = 0
• ZERO = 1
• 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
