Sorry I never got back to this, I think I wasn't receiving Steam notifications for discussions last year.

The asteroid ore distribution on asteroids is hard-coded in the game and not moddable.

Even if you reduced total kinds of ores in the game, it would have just as much in whatever kind of ores it still has to select from.

On planets, it's not procedural either, just as the landscape is identical every time, so are the ore deposits. Basically there's a picture map that you "color" where the ore deposits go, with each color corresponding to an ore in the corresponding planet data file.

Let me know in the pinned discussion what sort of changes you would like in a coming update to go with the survival update.

Thanks for the response, a shame that it's hard-coded. I'm working on a few mods to meet my masochistic needs, thanks for the inspiration with this mod of yours ;)
