Implementing custom races with blender with the creation kit and understanding how it works

[Issacreaper2]

Hey guy I wanted to ask you something I wanted your opinion on how I think custom races are made so I went through and did some digging in the game files using B.A.E and I looked at the super mutant head nif file then I looked at the mouth nif file and then I started thinking about this mod right here DC and West Coast Supermutants at Fallout 4 Nexus - Mods and community (nexusmods.com) and I noticed how their lips weren't animated. Did make new models for the face and did not rig the face at all and leave the mouth as is for its animation because if that's the case I feel a little better now when it comes to creating a new race
