I started modding a few days ago and I uploaded my mod to the fallout nv nexus (so far is just one stat edited weapon) and got feedback saying i should make a custom model, I have NO idea how to even start, I was told blender would be a good tool for making a model. Any tutorials you guys could link me to, or better yet message me skype details and tutor me directly (with a credit in the mod where its due).
