Do what you want, pal. I think the area where Han dies would be a great duel map, and feels like it would fit into JKA very well. Reminds me of the Imperial duel map, but much bigger. Rey's home would be cool as well though.
Just follow Rich Diesal's mapping university and that will give you a great idea of how mapping is done. If you find that you enjoy it, move on to more complicated things, since it only covers very simple mapping steps.

You bastard. So good at this. I was wondering if you'd ever get to it. Really excited for this! It will be great to compare your work to the old clone models.
Why not use that older build I linked, since it seems to work, according to your video? I link to the version of JA++ that I use as well. Everything works for me no matter what server I join. I've stopped pointing people to OpenJK on Mac because of all this though. You want to just go back to using vanilla by using JKJALaunch.
I think by "crappy" he meant as a person, not necessarily the quality of their mods. A person that takes other people's work without permission (and especially if they claim it as their own) are indeed that: crappy.
Try this: https://thejawaclan.com/topic/40385-ja-osx-mac/?do=findComment&comment=413796 I still use an older build of OpenJK due to these problems. But using the older SDL version seems to work for newer builds I think. Either way, that post I linked should resolve the issue until it's fixed by the OpenJK devs. Also, your base folder is different in OpenJK. It's in ~/Library/Application Support/OpenJK
