Do the geothermal vents spawn on surfaces other than Nauvis? Especially thinking of modded planets.

Hello,
For now it is only on Nauvis, as other Factorio Space Age planets have their own energy generation means.

It could be added rather easly to also have geothermal vents on any planet surface but it may break balance regarding petroleum generation (for energy this should not be too much of a balance problem).

Do you have specific planets or mods this would be interesting to add ? Worst case I can add a mod setting options if it breaks balance but people still wants it.

Some planets where adding steam vents would reduce the challenge:

• Corrundum: Having steam (and as a result, water) can help balance the delicate mix of chemicals
• Fulgora: In large bases, water can often be a bottleneck/limit.
• Muluna: Muluna benefits from water for greenhouses, nuclear, early energy, etc
• Paracelsin: Heat and power substantially reduces the challenge
• Aquilo: Heat, power, and water all reduce the challenge
• Terra Palus: early and sustained power can help against the crushing enemy waves
• Nulla: Early power

There are other planets that might benefit, but I haven't played through those yet.
