I have added a new Q&A in FAQ as instructions for mod authors of modded equipment. Please ask your favourite mod author (Nanobots mod in this case) to add the lines.
Q: I am a mod author. I want some of my equipment usable on engineering suits, what can I do?
A: For basic engineering suit, please add "armor-early"
to the list in equipment categories. (Something like categories = {"armor", "armor-early"}
in your equipment prototype declarations.)
For the more advanced engineering suits, equipment with category "armor"
are automatically supported. This means anything usable in vanilla power armours are also usable in them.
The reason to change in equipment mods, rather than armour mods (this mod in this case):
It is much more likely the name of those mod equipment may be changed for any reason (like authors giving prefixes to names, adding multiple tiers, etc.). Thus appending category from equipment mod side would be a smarter way.
In comparison, I would probably not rename this equipment category "armor-early"
. (Unless vanilla really decides to use this identical category name, which is highly unlikely.)
