First time trying to configure engines using waterfall, I've come across this issue where I am getting log spam only when the WaterfallFX Editor is open, this is on 1.8.1 RO/RSS with RO Engines etc...
This is the simple config I set up.
Further adventures with the Mariner Outer Planets Expedition. KSC budget requirements froze the technology to several years earlier resulting in a more primative, but cheaper mission.
I'm still tweaking them and trying to get a solid setup of 5-6 different configurations for different situations. Once i've got that down i'll send them over or possibly create a thread. Originally I used Zorg's but I wanted to branch off a bit.
