Hello,
Some time ago, Arcimaestro Antares created mod that added animation to Vivec, which made him play a lute. I recenetly tried that mod, but since I have "Improved animation support" ticked in MCP and also use AnimKit, it required fixing the xLordVivec.nif via AnimKit "Fix Animation Errors" function (otherwise I got error saying something like "Error object Bip01 Toe not found..." or something like that). When playing with the mod, I later found out odd problem - when I fight Vivec and when he is punching me, a lute will appear for short moment in between his punches. You can see the problem clearly here: https://www.youtube.com/watch?v=A8CS8YlEzF8
I PM'd Arcimaestro Antares and it seems the mod works without this issue for him. He also does not use AnimKit. That's why I would like to ask you, if you would be willing to give the mod a try and report if it works for you (and also please post whether you are using Improved anim. support, AnimKit and if you had to fix the files).
Here is the mod: http://www.mediafire.com/download/9kdlrx521tn4cmp/Vivec_Musician.rar
Thank you very much in advance
