Did anyone get it to work? I'm always getting the first one (upper left)

bool Function PlayImpactEffect(ImpactDataSet akImpactEffect, string asNodeName = "", float afPickDirX = 0.0, float afPickDirY = 0.0,								float afPickDirZ = -1.0, float afPickLength = 512.0, bool abApplyNodeRotation = false,								bool abUseNodeLocalRotation = false) native

In function parameters there is nothing that suggests random texture rotation, so I guess it should rotate by default if picked in CK.

Thoughts?
