[1.8.1] Less Real Than Real(ism) - RP-1 With Less 'R' [v1.2] in Add-on Releases Posted Monday at 06:33 PM 7 minutes ago, boribori said: Yes, that was it! And some of those screen texts were actually quite helpful Thanks! I found the tree config and now I know what to research first. I initially thought I couldn't get any rockets in the air just because I hadn't played early career in ages and wasn't used to launching without ascension guidance. Now however I fear it is because of FAR. When you start there seems no possibility to build an aerodynamic rocket. The only option seems to be the Stayputnik. Is that correct? I first want to play LRTR as it was intended before I start changing too much, but eventually I will probably want to write my own KCT formulas. Do you have a document somewhere that explains what your formulas do? I find this document https://github.com/magico13/KCT/wiki/Preset-Formulas-and-Math-Parser-Documentation very difficult to read. 1) Glad it worked! I'll fix it for the next version. 2) Yes, in stock, the stayputnik is the only option. Really, the only starting option in stock is a stayputnik with a small SRB and some fins. I call it my 'bottle rocket' era :-) I never tested it with FAR and it's not clear to me how rescaled aerodynamic parts will work. I'll add it to my 'things to test' pile. You could play with the number/placement of fins and adjust the thrust of the SRB motor so see if you can get a viable rocket. If you want some more flexibility you can add Completely Non-Aggressive Rocketry. It gives you a V-2 like rocket from the start and works well with the mod. 3) KCT configs are a bit black magic to me. I took this directly from the RP-1 folks and I modded it a bit for LRTR. You will likely need to ask the folks over there or KCT for guidance. Oh, and thanks for the feedback! I took a look at the mods you added from the discussion thread and will add them to the supported list when I can.
