This is a great mod and the models are so detailed! Just a few things: I installed this without realizing that you needed TU to make the starship shiny. https://imgur.com/a/PVD1X9f Note the engine plumes on the booster.
Then, I went back and installed TU, and now the engine plumes are gone. https://imgur.com/a/F5SsyKs Also, what is this? https://imgur.com/a/RyIcXlv Note the oxidizer levels...
Also, I feel like I should mention that the singular raptors (SL and Vac) have had plumes the whole time, it's just the boosters (29 and 33 engines) that are affected.
