This is a quick guide on how to add mod compatibility for any mods not covered by the hub.

This guide assumes you have an understanding of RFPM - if not it is fairly easy to pick up.

Step one:
Copy the land_units_tables and main_unit_tables data for the units you want to add compatibility with, into the land_units_tables and main_unit_tables in the hub mod.

Step two:
RFPM will likely show errors where it cannot reference any modded data entries. Change these to any base game value. This step means that you can enable/disable unit mods as you like. If you don't change the values to base game values, you will always have to have those unit mods installed.

The land_unit_tables and main_unit_tables in the hub mod are dummy tables and will be overwritten by any unit mod you have installed. Just pick any base game reference for that data type.

Step three:
Copy the key from main_unit_tables (not land_unit_tables!) into unit_purchasable_effects_set_tables. You will need to add a line for each upgrade you wish to add to a unit.

The Purchasable Effect column is where you copy the key for the upgrade you want to add to the unit. Easiest way is just to copy from a similar unit already on the list.

Some factions all units get the same upgrades, for others they get a selection. Just choose whichever you think fit.

The "Is Exclusive" column is where you set whether the unit can have more than one upgrade. Tick to allow only one upgrade to be chosen.

And that's it. It's a simple process once you get the hang of it.

Troubleshooting

The game crashes on launch:

This can be generally be two things. Either:

You have copied the wrong data into the main_units_table or land_units_table

There are non base game references in the main_units_table or land_units_table. This one can also occur after an update where CA changes the base game data values. RFPM will flag the updated data values, just change them to an up to date base game value.

Units aren't showing upgrades:

Check:

Have you copied the correct key from main_units_table to unit_purchasable_effects_set_tables

Has the unit mod author pushed an update that changed the unit keys in main_units_table. If this has happened the new unit keys will need to be added to unit_purchasable_effects_set_tables.
