So I got completely sick of running around Google and finding 9 year old tutorials on how to get an animation set up. I want to make a friend a twin-tail and I figured since I know how to rig and animate in Blender, I would animate it as well. But what I want to know is that if I make the animation in Blender and attach it to the tail in SL, will the animation still work? And if that doesn't work, what is the best way to make and attach an animation to something like a tail. I prefer not to have to do the prim hiding trick since I don't want to lag him or anyone else with extra prims.
