<HexSectorSize>380</HexSectorSize>

MapSizeDefs.xml

No idea what happens if you make it bigger. (Map sizes are hardcoded in the schema(dll) so no new ones via mods)

What i think he was saying is that you can increase the number of planets, and habital planets. I never could mod this above 3150 habital planets i think with patches they kept shrinking it down, so i gave up. I think this is in mapdefs in both directories. No its not stable.

Change the value I posted above (for insane). It will make the map bigger, but, theres bound to be a limit in the engine. Once you hit or go over it, it will CTD.

I changed it to 50% bigger.  It crashed during galaxy generation.
I then tried 25% - another crash.
10% also crashed.
I then increased by 10, to 390.  Crash.
I then tried an increase of 1, to 381.  Crash.

So, I went back to 380.  It worked fine.

These were with scattered stars and everything on Normal, and I have 32GB of RAM.

I guess GalCiv3/Stardock doesn't want some of us to get more Insane than you we already are.

Hm, I just measured my insane map by placing a ship with enough range in the upper left corner of the map and ctrl-hover over the the hex in the upper left and middle right corner.

For the upper left corner it says Distance 380 moves, for the middle right corner Distance 381 moves what I don't understand since for a symmetrical hex map both distances must be the same ... ?

Anyway, that would mean despite the xml entry of 380 for HexSectorSize the real size must be 381 or 382 hexes, and it means the number of hex fields at the edge of the map from one end to the other or from the center hex to either edge of the map (including the center hex). That's 434,341 or 436,627 sectors altogether (the formula is 1 + (1 + (r - 1) / 2 * ( r - 1 ) * 6 with r = radius of the map in hexes, giving 1 sector for radius 1, 1 + 6 = 7 sectors for radius 2, 1 + 6 + 12 = 19 sectors for radius 3 etc.

With every new radius R the overall sector count increases by (R - 1)*6 hexes.

And now I hope I didn't miscalculate

Ok - but we still need larger maps!

I think    <HexSectorSize>760</HexSectorSize>     should be enough for the first time

I have done of a lot of work (and math!) on the galaxy sizes since the Beta.  I started using the number of hexes on side instead of the radius because I found it easier to count.  The hexes on a side and the radius in hexes are the same.  I began using HexSectorSize because I no longer had to count.  The actual size of a side or radius of the galaxy is HexSectorSize +1, so a HexSectorSize of 380 means the actual size of a side or radius of an Insane galaxy is 381 hexes.

The formula I use in my spreadsheet is =1+6*(HSS+1)*HSS/2, where HSS is the HexSectorSize.  I confirmed this by counting sectors in the smaller map sizes.  An Insane galaxy with a HexSectorSize of 380 has 434,341 total hexes.  My formula is slightly different from lyssailcor's because I use HexSectorSize, and he uses radius.

Since we all will soon have machines with 8-core or more CPUs, 64 GB or more of RAM and at least 2 very-high-end GPUs , I think bigger galaxies should be in an update before too long.

  Sorry, I couldn't help myself.
