Hey @Kartoffelkuchen,
I just downloaded your mod and I have to say, the models look fantastic! It came to me that while I tried to load in the Falcon Heavy, it had the missing parts and modules and when I tried to load the Falcon 9.1.1 (something like that), almost all of the center pieces and fuselages weren't there. I can only imagine that either I downloaded it incorrectly or the file I downloaded was corrupt ( i redownloaded it and it still didn't work). I followed the parameters in the readme.txt file as much as I could and I kept getting the same errors. Is there a fix or are there any videos on installations? Maybe I am missing a dependency?
Edit: Also turns out I installed the rescaled incorrectly but got the same errors after redownloading and installing it correctly.
