Era-related build restrictions

[Zangdar]

Hello eveyone,

I am looking for a way to change some of the build restrictions due to eras in GC, especially with NR so that I can be at full strength at the same time as the IR.
I noticed the TechTree file in the xml folder and that there are different variants of the ships with a tech number ranging from 1 to 5 that matches their era availability, but adding manually one or several lines based on the same model did not work.
Since my non-existent abilities end here, I am asking for help ^^

Where are the files that I need to change and how can I change them please ? I would like it to be reversible so that I can have the best challenge in The Art of War or Essence of War, while still being able to go back to the normal settings so that I can play the historical GCs with the appopriate ships according to canon.

Any information would be most welcome, thanks

The Techtree xml is actually just full of dummy entries used to populate the in-game tech tree page in the droid log (which I'm pretty sure is out of date anyhow).  Depending on what exactly you're trying to do you need to be editing either the tech level in the unit entries in the unit xmls (e.g. Remnant_Space_Units.xml etc), or the lock/unlock scripting in the GC story scripting files.  It may be that you need a combination of both to achieve what you want.

Allright thanks, I managed to understand how the tech level translates into eras 

One question still : this allows to unlock late eras units in previous eras, but how do I do if I want to maintain the availability of early era units in the late eras ?
For example the MC80 is tech level 0, same as the corellian corvette for instance, which supposedly means available in eras 1 2 3 4 5. But the corvette remains available anytime whereas the MC80 is only available in eras 1 2. Where is the piece of code that determines that ? I couldn't find a relevant factor in the unit entries...

You don't need to have them build available as long as you have built them before and the ship wasn't destroyed you'll still have them.

As Slornie stated above, the campaign story script files are what you're looking for. The build restrictions are campaign-specific.
For Art of War: XML\Conquests\ArtofWar and edit StorySandbox files. To remove build restrictions, remove the relevant unit locks from the files.
For MC80:
   <Event Name="R_Lock_MC80">
      <Event_Type>STORY_TRIGGER</Event_Type>
      <Reward_Type>LOCK_UNIT</Reward_Type>
      <Reward_Param1>Calamari_Cruiser</Reward_Param1>
      <Prereq>Rebels_Enter_Tech_03</Prereq>
   </Event>

 Allright, thanks to all for the info =)
