I would like to create a mod of SCP or Slenderman for Skyrim SE, the problem is that I don't know where to start, should I model a 3D character in Blender and animate it? Create it's own bones? Should I create my own textures? Should I create his own bones for him? How can I import the character, textures, bones, etc to the creation kit? They may be obvious and a bit silly questions, but I'm new to this and I don't really know what to do. Any help is welcome Pd: Sorry for the bad english tho
