Hello everyone, i am totally new to modding and i would like to learn. I am grateful for any advise or help regarding Nif/kf/dds files. Up to now i only repainted some textures but i would like to edit 3d models too (nifs) and change/ add animations (colours or direction). Anyone can recommend good threads/tutorials/guides musthave programs or tools for total beginners regarding this topics? Software i use: Nifscope, Blender, 3ds max, photoshop :) Thanks in advance!
