So, I'm getting a PC next month and wanted to do some modding in Skyirm, but I have a few question

1. Is it possible to set the Werewolf model as a new race when you start the game?

2. If so, would it be possible to add options to the model like the other races(ie, fur color, snout length, scars, face paint, etc.)

3. How difficult is it to make new armor and weapon models?

Ideally, I would like to implement a Lycan race that has at least some customization like the other races and make some custom armor and weapons for them.

3. the learning curve is steep.

you need a 3d program like 3ds or blender, start with blender its pretty intuitive and ofc free, it will probably take about a month to really grasp, then depends on how much time you want to spend on making the model look. Then you need to make textures, that requires a 2d paint program, gimp is free or photoshop, which takes even longer to master. I've been using photoshop, and taken courses online in photoshop and im still not all that great at making great looking textures.

Then you have to get familiar with the niftools exporter and then you'll spend a few weeks learning nifskope to actually get the models and textures in game.

you could get a very basic sword in game in a few weeks if you focused solely on it. then it will be easier the more time you spend on it
