I have released an updated version for 1.0 here:
https://steamcommunity.com/sharedfiles/filedetails/?id=1558009426

This uses xpath patches, so it should be compatible with all mods with no dependencies.

Will you be updating this to B18?

B18 please.

since this mod makes sense and worked in a17, is there going to be a compatible version for B18?

Thankyouthankyouthankyou... loving this mod.

Thanks. I may consider to create a personalised mod combining all these excellent mod.

At least it can have a badass wall around it

Other mods which do allow building the ship reactor inside (at much less power):
[FSF] Improved Ship Reactors
Antimatter Reactor

@VoidVoice
The only thing this mod does is change the power output from 1 kW to 15 kW, so the rest is default.

So, it is still prohibited to build a Ship Reactor under a roof. But why should it be allowed? This thing is huge ! It's probably more than 1 story tall. Also, ship parts are all modular. You're looking at the exterior of the reactor section of a starship.

That said, I may considering increasing the hitpoints so it can take more punishment. Sometime soon I plant tol convert this mod over to the new xpath patch system. I'll revisit the idea then.

Can it be built under roof?

Now updated to A17. I just added "false" with <canOverlapZones> tags, which was the only change A17 made to the Ship reactor. But I doubt that would have prevented the old version from working.

As for how many kilowatts this should provide, that's a matter of opinion. There were already two mods that made it 10 kW, but I felt that was under-powered for antimatter. And when you consider this is end-game and requires both a lot of research and materials...

But 72 kW? That sounds pretty excessive. That's more than most colonies ever need, no matter how big they get.

I'm wondering that too.....

Does this already work with A17 or does it need updated?

With the explanation provided, it seems like it should be 72 KW. Otherwise, why modernise at all?

I felt like the 1k was a bit of a letdown myself, so I do like the idea of this mod, however I cant help but feel that 15K might be a bit of an overadjustment considering It provides unconditional energy and all...

wait anti matter dats nuts as 2 metal bois
