Just now found this thread! This is awesome! Iv'e been messing around with modding here and there for about a year now. And now that I'm stuck in the house for who knows how long, this is all i been doing. So far Iv'e made a fuel tank, nosecone, cargo bay, stack adapter and a wing. Nothing to brag about but I got them into the game and they worked so I was happy! I also made a command pod and am also struggling to get the lights to work. Iv'e been trying for 2 days strait, literally! I can not do it! I've tried everything and now I'm starting to wonder if my unity install is messed up or my part tools is wrong. I'm using unity 2019.2.2 and the latest Part Tools.
