Is there a way in the configs for shortening the track connection tubes that go between each biome sphere? If not, can that be added? I can't see how to do it in the configs currently, but I could just not understand how something works.

Making the biodomes closer together, which would then shorten the distance that these tubes generate.

Currently it looks like this:

O-------O-------O

I'd like to have a config option for doing this:

O---O---O

Ah you mean the distance between the spheres. No that can't be configured I'm afraid

Can't be currently configured or can't ever be changed due to some code limitation?

Mostly the first but note that bringing them closer together will make it perform less well. Personally I think they are already very close to each other

well then I would like to request a config option to play with if possible. It isn't critical of course, just something I'd been wishing for for a while. I'd put them a bit closer so it doesn't take as long to get from one to the other. I haven't had any issues with performance, but I'm using a beast of a computer.

Space Prefab? are you posting on the correct tracker?

It's the world generator that does the biomes in glass domes connected by quartz railway tubes. I think it's called the space profile. It's not a prefab, but profile.

What exactly do you mean by 'shortening the track connections'? I don't exactly understand your request
