This is a easy guide to make custom mounts
To make this mount u need to follow my steps
Get an mount you want to change ( i use "Horn of the Timber wolf")
Get Entry number of it ( search in your DB in Creature_names ) (i use 1132 )
Go to Creature_names and change the name of "Horn of the Timber wolf" in what you like.
Now go on that mount and see what the name is of the mount ( here: Timber wolf)
Go to Creature_names again and search for your name + mount ( here: "Timber wolf Mount")
Change the name again and change the DisplayID in the DisplayID your mount have to look like.
U cant use every DisplayID, some ID's dont work good so you can try them ingame with: .mount "displayID"
How to Find the DisplayID:
Look in your database "Creature_names" or go in game and if you see a beast that you want as your mount left click the beast / npc and typ: .npc info there will be a list and there is also the DisplayID number.
I hope this guide helped some people.
