The most important thing would be to know the exact settings. What is what, what is suitable for what.
The second is that I want to learn how to make waypoints, because I have some good maps I want to make for our community and for myself.
Unfortunately, I see that after 20 years, the helper annys have disappeared from the internet. There are only waypoint generating videos for ET, but we are RtCW fans. It's not easy to find people who can help with this after all these years either.
The Discord ET community for example has not been very helpful...
