First, can anyone suggest some Male Heavy compatible keyframes that have animations for using a club?
Second, I have noticed that I have some skins that have lightmap.tga files and some that have male/female_(whatever)_lightmap.tga files. Will the meshes read either one? I've been looking in the meshes with Nifscope, and so far they have always referenced m/f_(w)_lm files.
I don't know about animations that are specific to a "Club". However, both Tommyboy and Grenadier have "Executioner " Meshes, and I'm sure there are other Male_Heavy based Meshes with Weapons as well.
As for the Lightmap question, some Meshes have multiple Lightmaps, and I have also seen instances where Skinners have put the extra Lightmaps into their Skin release, as a way of giving us a choice as to which one we use.
