One question I have though is about the Modified Idles and Skeleton for Facial Expressions package which is available on the Groovatron Nexus page, which is needed to enable character facial expressions. Do the meshes and the skeleton. nif files replace just the head, or the whole body? I'd like to not have my character look so grim all the time, but I'm using a Type 3 body replacer and don't want to run into compatibility issues with that. The Nexus page isn't very clear on this point.
Thanks!
