It would seem that SKSE has a function SetWeight(float w). Any tips concerning this kind of mod would be appreciated. Now, I think this would be a pretty simple mod to make for someone who knows where to find the spawing scripts, just roll a number between 1.100 when spawning any npc and set the weight. I think I found the cause for carbon copy bandits after a few minutes. Looking at the amount of templates, it would seem that the spawn logic just picks from a pool of pre-generated bandits and that's it. Naturally I went digging around Nexus for a mod that would randomize this, but couldn't find one. Having random weights would be really nice, especially if using a body that reacts more to the weight slider, such as CBBE or something. I noticed that random spawn npcs have very little variation in body weight.
