I've not done much with Cartographer, so I hadn't realised there'd be such an issue with adding a glow to the symbols. There is a small glow built-in to the star symbols, but I agree a larger glow is really needed to show clearly what the object is when you're viewing the map at a distance.

The Red Sun system does look a little better.

If you still want to swap the two systems, I think you will be better moving the systems manually.

You could use rotate, providing you know the exact centre of the main orbit on which both systems lie, but this will also invert everything in the process.

Mirror copy would keep all the orbits and objects in their same relative positions once swapped to the opposite side of the orbit (don't do this on the labels though), but you would need to drawn the mirror line very precisely at an angle to accomplish this, AND mirror copy will force everything onto one Sheet if it wasn't to begin with. Plus you couldn't swap the two systems in one command, so one would overlap the other after the move (unless one set is on a different Layer, which you could hide before-hand).

Maybe mirroring or rotating the background star image would work instead? It would certainly be a simpler operation!

Been there, done that (albeit quite some time ago now; for the Nibirum = Community Atlas system, for anyone unfamiliar)!

Should be a good one regardless of that, as it's an interestingly different style of mapping to work with, compared to what most of us here normally map.

Snowy roofs looking good now; perhaps not so "realistic" in the strict sense, but we already discussed that above, and they do look the part to me.

Not so sure about the pentagonal igloos (and yes I know they're actually the detached add-on dormers window roofs!) 😉

[Although they would actually work quite nicely as sheds/small huts partly buried in snow drifts too, more seriously.]

Looking fine.

Maybe add a few scorch marks in front of the fire as well? And worth looking through the "Debris" symbol catalogues for a few suitable stains, perhaps?

One or two of the symbols might need moving slightly - the bedroom table seems to be embedded in the wall, currently, for example.

And maybe add some more windows? (Or at least a ventilation hole for the toilet!)

Hand-drawn hatching of any kind shouldn't be perfect; the trick is to get it to still look good in the final item, and I think you've managed that very nicely!

The azimuth is indeed counter-intuitive if you're used to the real-world standard usage (and note that it also runs counter-clockwise from east, NOT clockwise!). I ran up against the same problem some time ago. Apparently, mathematicians (and thus computer programmers/programs) work in this alternative fashion. Which as I said at the time confirmed my long-standing prejudice that mathematics has nothing to do with reality after all 😉

Good luck running the game!

It's the same in physics, Jim; "Big Bang Theory" TV show reused the spherical cow as a spherical chicken instead as a joke. All most amusing, even if sadly all-too true as well!

Just turn the lights off, and ask them "does the dark matter?" 😉

It's because it's a snowflake design really, Sue - we can tell! 😉❄️
