I have no idea where to start. I've done some modding, but never created my own mod.
I'd like to make a mod where there is a large tent with a vendor or vendors who sells special equipment for different factions, mostly having to do with frostfall and other mods surrounding that. So Like I am envisioning different factions having different cloaks and tents and things like that that these vendors will sell you. I was thinking it would be placed near Whiterun city. Cloaks are fine, but I would like something more specialized for each different faction. So say the dark brotherhood would have a jet black bear coat and the college of winterhold would have think robes that were closer to a dark purple tint or something like that. Also, I'd like to be able to buy the recipe for or by different factions tents. This would signify that you are of that faction. This would mean that you might get visitors from that faction to join you at your temporary home. Would be cool to implement as similar thing that Fallout 4 has where your tent could get attacked when sleeping or something. You would get interrupted by your faction buddies waking you up and telling you that we are being attacked.
That is my pipe dream at least.. So if anyone knows how to get started on making my own mods, I would really appreciate it.
