I don't have the mod, so I can't see what is there.
As far as I can see from the modding guide and files of other mods/base game, there are two possible things.
In the races file, you may have that all the others have a special component.
The zenox got this in their file (Races folder of the mod):
'Special Component: -1 = None, 0 or greater = ComponentId of special component. Be careful not to set a special component to a race that is also required by other races
It probably points to their special shield tech.
There is also a section disallowed components that could be set, the zenox have none, though. (components.txt in the main mod folder)
'Disallowed ComponentIds: comma-separated list of component Id values that cannot be researched by this race
You do of course have to check in the component section to figure out the Ids.
We saw id 36 for the zenox
36, Megatron Z4, 36, 0, , 40, 9, 0, 155, 12, 0, 0, 0, 0, 0, 6, 4, 14, 4, 13, 8, 3, 3, 7, 2,
That is their shield tech, see if you find Megatron in the special zenox research branch (research.txt in the main mod folder).
I searched for 36 until it showed up in the componentIds.
PROJECT ;86, UltraFast Shield Recharging, 2, 6, 1, 16, 0, 0.0,
PARENTS ;95, N
PROJECT ;87, Capacitor Overloading, 4, 6, 1, 16, 0, 0.0,
COMPONENT IMPROVEMENTS ;36, 4, 195, 15, 0, 0, 0, 0, 0,
PARENTS ;86, N
PROJECT ;88, Pure Energy Discharge, 6, 6, 1, 16, 0, 0.0,
COMPONENT IMPROVEMENTS ;36, 6, 245, 20, 0, 0, 0, 0, 0,
PARENTS ;87, N
So the Zenox has the 36 special component (only theirs) and there are research projects influencing it.
So this is how you can do it. Look in the race files of those that have/have not and see which of the two possibilities are used. Add the necessary Ids to the Tyrandis race file.
Edit: Whenever you change files, make a copy first so that you can undo stuff if you mess up. If you put invalid Ids you are likely to experience game crashes when running the mod.
