Hey man, I use Inkscape at the moment. I am trying to learn how to create both map and environment, but I can't find good tutorials for them in vector art form, so I hoped you maybe could tell me a bit how.
Inkscape is cool. Although, I use Affinity Designer for my vector stuff but they are both quite similar.
Not sure if this helps, but i did do a few tutorials on map details for my youtube chan. But it's for AD, however, the principals should work in any vector program (I would think).
