I too am getting a log file filled with messages like: [07/16/2012 - 09:03:30PM] error: (000C6982): cannot find variable named fToggleBlend. stack: [ (000C6982)].FXSetBlendVariableScript.SetAnimationVariableFloat() - "<native>" Line ? [ (000C6982)].FXSetBlendVariableScript.OnLoad() - "FXSetBlendVariableScript.psc" Line 38 I did some searching and the script in question is used in 5 activator types in several Avanchnzel; thing is these seem to use a model: effects\FXSparkFountainToggle.nif, which in turn points to a behaviour file: genericbehaviors\blendbetweenstatesvariable\blendbetweenstatesvariable.hkx which DOES in fact contain the "fToggleBlend" variable name. So I'm a bit stumped as to why I'm getting this error in my log. I suppose the script could be modified to not call the set function on this variable, but I have no idea what this would do, since the function has very little documentation.
