Great, nice to add engines from this pack.
couple of things.

• NERVA I: engine is way to small, nozzel dia should be about 2.95m (it's a big engine)http://www.alternatewars.com/BBOW/Space_Engines/ROVER_NERVA_Engines.htm
• NERVA II should be larger too (same link)

i'm not sure about the emissives, my guess would be to try @heatProduction in the ModuleEngines*. Though i see a different bug, they appear cool on the launch pad, but then warm up visually(but only a little)

to remove non RO parts you can use !PART[Part_Name]:FOR[RealismOverhaul] {}

Thanks. I couldn't find any information about the Nerva 1+2, only about Nerva Alpha/Gamma, including their pictures - seems like the latter two being small scale versions for the space shuttle payload bay.

Tried that, also removed the RO version of the engines.

I'll do the rescaling next. Gonna check the @heatproduction again, but otherswise I don't think it's much of an issue.

@Temeter If it removed the parts then something is off (not with the current patches, the MM passes for them are OK). Did you double check the part names? As i see from the part names, it does not seem very difficult to mess up some of that "encoding".

@PhineasFreak Still removes RO engines. Basically, the top of my file looks like this for me:

!PART[ntr-sc-25-1]:FOR[RealismOverhaul] {}
!PART[ntr-gc-25-1]:FOR[RealismOverhaul] {}
!PART[ntr-gc-25-2]:FOR[RealismOverhaul] {}
!PART[ntr-sc-125-1]:FOR[RealismOverhaul] {}
!PART[ntr-sc-125-2]:FOR[RealismOverhaul] {}

@part[ntr-sc-25-1]:FOR[RealismOverhaul] etcetcetc

I've copied it almost exactly from another RO mod config, probably I'm doing something wrong?

I think there generally might be something weird going on with Kerbal Atomics. IE, without those entries, all engines stay - except the Stubber (smaller bulky thing I made Nerva 2), which actually gets replaced.

Hmm, maybe the base part modules are copies of the other parts (that get removed by the RO pass)? I cannot see any other reason for these parts to fail.

On a more positive note, the correctly scaled Nerva 1 still looks good, despite being over 10 meters high. Nertea makes awesome models! The stock Nerva is actually scaled too small.

Now the Nerva 2, plume adaptions, and we're ready to go.

Ok, fixed all that nonsense :D

Done now, I've updated the dimensions to mirror the data points, and the plumes look good too. I might switch around models with the new KA 1.3 engines (eel in particular), but that's for the future.

IMO it's ready to be added, if nothing else comes up. Those minor issues aren't too relevant.

Sorry, I don't really get how that stuff works. Mostly learned by checking stuff out. As said, it's already weird how the Stubber gets replaced just fine, but not the other engines.

Cool, looks good except the plumes look rather undersized to me, on the NERVAs atleast.
This is most visible when testing them at sea level. consider using a similar plume scale to the stock NERVA.

Done, increased it to 2.25 and 2.5. I'd almost like to make them bigger, but then the FX starts becoming pixelated. :/
