Overview
I’ve written a guide on prototyping in reflex a while back, you can find it at the official forum http://www.reflexfps.net/forums/index.php?/topic/2018-fast-prototyping-3d-sketching/
Prelude
Starting off with the editor I’ve tried to sketch something on paper to get the idea of what im going to be building but I do not have any technical education background so kind of technical drawings didnt resonate well with me.
The beginning might be difficult so I think its good to start building a map with major item placement in mind. Just come up with the simplest idea like MH room in the middle, RA room on one side and YA (aka out of control) on the other, yes this is aerowalk but its also silence and its just something that ‘works’ you can make it work more tactical like on silence or more ‘hectic’ like on aero it depends on size and connections. You can come up with different combinations ofc but I think that its best to figure out what combination you’re going for first and lay out your map based on it. If you decide to go for only two rooms RA/MH go for it.
