While not a current WIP, my first exercise to learn C4D sooo many years ago was to model the Death Star Reactor Chamber. This was done way back with R9.
Not bad for a first attempt with C4D using R9. I owe it all to Nigel's blue airplane tutorial!!!!
Right now, I am more into Star Trek than Star Wars with my STIII Space Station WIP in full swing. To be honest, I loved that world and only mildly winced during some of the more awkward moments of the prequel trilogy (sorry...Jar Jar Binks just didn't do it for me). But with great love and affection, I overlooked some of the bad writing ("Are you saying love is blind?" -- ouch) and went to see every movie in the theaters when they came out. They were events and needed to be seen in a movie house on the biggest screen you could find with full Dolby stereo blasting at you!
That all ended with The Last Jedi. I will leave it there. Please don't convert this thread into a Disney SW bashing party. There are plenty of other sites out there on the web for that. Rather, let us cling to the great memories from the late 70's and early 80's when we watched that saga unfold for the first time and sat amazed at it all.
