It is Neo-Standard compatible, but not
required. All vehicle sizes use a stock image as the secondary, so if any images it wants to use are not there, it will have a backup.
In fact, Adamant calls for a lot more ship sizes than the Neo-Standard has, but will likely never be made for any sets (as there are a lot of them
).
I would not be opposed at all to you making a Zanar'ri AI for Adamant.
If you could, please keep a log of all changes you make to get AIs to work in Adamant, so that I (and others) can have an easier time of adapting AIs to the mod.
