Fighting style modding via ide is no longer a viable or supported method of modding so it is best not to ask about that since very very few if any modders still mod via this method.
LUA modding is the way to go to get proper working mods since ide modding directly is very buggy and you will be VERY limited in what you can accomplish modding this way.
Rise and I DO have a way via lua to completely bypass ide directly but that method still has some flaws that we will try to work out and as such will not release this method until it is working flawless.
You can do flawless mixing of styles and moves via LUA though and eventually either I or another member of the modding team will release a tutorial or two explaining how to do this while keeping Jimmy's style intact.
