Hi guys! I've recently created a mod that simply add an horse to the game (yes, another horse..) I'd actually like this horse to follow me in the Shivering Isles, how can I do it? (if I can do it, of course!)
Thanks! and excuse me if the question is banal

Yes, it's possible, but requires alot of additional scripts to move the horse around. Additionally, since none of the places within SI are setup to handle horses, there will be other problems when dealing with the various doors and gateways. Horses were left out of SI for a good reason, the systems which make horses work just cannot function properly within SI.

I added a mod that gave me a Shivering Isles Stables. You could add your custom horse to the ones in the mod, or replace one of the ones in the mod with your own textures. My Shivering Isles horse works fab! Which reminds me, I have to go rate that mod a 10!
