Huh. I guess you could reduce the energy of the reaction to make it realistic.

The game keeps throwing a 'Error Validating Materials' error, citing 'null reactants', 'null elements' and 'null elements' error for each of the modded items. Except for Metallic Hydrogen.
Not really sure what's going on here.

Make sure you get everything required and put them at the right place. Everything is in its proper text file in the mods/data folder. As far as I understand, chemicalreactions.txt goes outside the materials folder. Should I be editing the base game files and not adding modded text files? |

There might be problems with spacing, but I'm not sure. Maybe call other people? I'm quite busy now. |

Elements.txt does not go in the Materials folder. Whoops.

I wish every defination file had a corresponding user file.
Would make it much easier to troubleshoot everything.

Just a question. So I've been editing base game files because for some reason I cant get the mods folder to work. Is this truly really bad? I noticed when the game updated. It broke my mods, so I just use the steam validate integrity and that fixed everything. I mean I would love it if I could get the mods folder to work but it doesn't. (just to note I have a 1 Terabyte D: drive so I store all my games on there.) Don't know if this impacts anything. I know it does impact my ability to export files tho.

Modding the base files generally isn't bad if you just add stuff. However, if you edit core parts, like aluminium for example, you've got a pretty great chance to break the game. The mods folder should work provided you apply your changes in a similar system to how the game reads the vanilla files, you want the same file structure within the mods folder as you'd find within the base folders. |

Also, as a reminder, you name your file 'Fluids.txt' and 'Nonmetals.txt' like the base file, not 'Fusion Rockets.txt'.

Okay All I'm doing is adding stuff like metallic hydrogen and graphene for some fun. I haven't edited any of the base core files only added stuff. |

I decided to call the fuel 'Zubrol' because it sounded appropriately corporate. Properties are based on the 'example' NSWR described on Atomic Rockets, which assumes an 0.1% fission rate from a 2% aqueous solution of 20% enriched Uranium Tetrabromide, for an specific energy of 3.4 GJ/kg. This config gives 3.5GJ/Kg, which IMO is close enough. ChemicalReaction Zubrin NSWR

Here's the reaction. And here's an example fuel tank, engine and ship.    What you might have noticed is that the NSWR ship is very expensive (and very light) compared to its NTR counterpart. That's because its fuel/propellant contains a lot of fissiles. The Delta-V is excellent though, and this engine is overall far more believable than the Fusion Torch drive. Another thing to take note of is that because Zubrol is a monopropellant the game correctly classifies it as being explosive. Its energy content is an order of magnitude higher than that of any chemical monopropellant in the game, so I'd advise that you don't let the enemy shoot your fuel tanks- the consequences will be akin to a large nuclear bomb detonating inside your hull. The exhaust velocity came out a lot lower than Atomic Rockets predicted- I suspect that this is because our nozzles are much less efficient than he assumed due to inadequate expansion ratio (even 1000:1 doesn't get the exhaust below 20,000K). Any chance you could give us some guidance on how to implement this design. I've been working on it all day and getting nowhere. |

Will any of these designs grace the workshop? Or is it impossible and has to be done manually still?
