NiAlphaPropertySetSourceBlendFunction

This is a command from NifSE.

Syntax

(bool:success) NiAlphaPropertySetSourceBlendFunction short:blendFunc short:nifID short:blockID
(bool:success) NiAlphaPropSetSrcBlendFunc short:blendFunc short:nifID short:blockID

Sets 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.
