Step 1 - Enable the features desired:
If you want to disguise MythicMobs' mobs then set it to true in the config file. Similarly, do the same for Citizens' NPCs and Vanilla mobs. (http://prntscr.com/p645fz)
Step 2 - Generate a disguise:
To generate a disguise you have to run one of the following commands:
- /sk uploadByFile
- /sk uploadByUrl
- /sk uploadByUsername
- /sk uploadByUUID
Step 3 - Disguise the mob/npc:
To disguise your mob/npc, you have to add its name in the relative section in the plugin config, followed by the name of the disguise you want to apply to it.
You can find a list of the Vanilla mobs types in the main page of the plugin wiki or by clicking here.
Remember to delete the default examples to avoid the crash of the plugin during startup!
Note for Citizens users:
You have to spawn the NPC using /npc create <npcname> --type villager
