How to add compatibility?

It's very easy!

• add all your mobs models and configurations inside the ModelEngine plugin folder

• run /meg reload to generate the ModelEngine resourcepack

• open the plugins\ModelEngine\resource_pack\assets\ folder

• copy assets folder inside plugins\ItemsAdder\resource_pack\ folder

• open config.yml of ItemsAdder and set this option:

config.yml

overwrite-vanilla-models: false

• Run /iazip (and follow the hosting tutorial if needed)

Done!
