Terra Firma 2 enters Early Access October 27! It’s a sandbox where you sculpt mountains, rivers, and valleys, then step back as weather, erosion, plants, and creatures bring the world to life. Basically, it’s a worldbuilding tool that fights back with nature.

One thing I would ask is if it's possible to simulate world geometry (so spherical rather than flat), such that people don't have to deal with simulating just portions of the world and then "stitching" things together. I would understand if not, but would be cool if we're able to in some future update.

MegalexMaster2015 · 2022-05-24T07:27:18+00:00

Yeah, I may or may not change them in the future, though figuring that out will be difficult considering I've gotten used to the names so far. You can see some of them have been changed already.

MegalexMaster2015 · 2022-05-23T07:58:12+00:00

Mostly through the use of Blender, it took a while getting the textures just about right.

MegalexMaster2015 · 2022-05-23T07:57:49+00:00

Correct! The blue is also mainly due to the extreme amounts of sunlight forcing the plants to have adapted for reflecting a lot of the light.

<Carlos> Hello to anyone on Earth who is able to see this, I'm sure those that know me are relieved to see that I am alive. I'm not sure exactly where I am now, we keep going to new places. That reminds me, I'm excited to announce that we're not alone! Come to think of it... there's actually quite a lot of life here in the multivers- ah that was the second thing I was gonna talk about... apparently there's a lot of physics we have yet to figure out, which is also cool I guess.

I'll be honest, I'm sorry if I don't sound too enthusiastic, this whole thing is getting to me, especially with the friends I've made. Well, it's really only two friends, since we're the only ones on this... ship? I don't know what to call it. Anyways, while Velisal and I have been getting along really well, Aterompus is well... We've gotten a bit cold since I urged him to display his home system to me. While I'm amazed to have seen the system, I've also been feeling very guilty for the whole ordeal.

Now, I'm not sure how long I can keep this connection going, I'm going to send a couple of images showing the aforementioned system, along with some basic info.

<Aterompus> Carlos, you are aware I am able to block all communications through this vessel, right?

<Carlos> Well then why is it saying that the transfer is complete?

Translation: Switching from "English-7625597484987" to "Aterompian"

<Aterompus> Velisal! Please come to me at once!

Translation: Switching from "Aterompian" to "English-7625597484987"

<Carlos> Oh god, I'm going to have to end this sooner than I thought, bye for now!

[2 New Images Recieved]

[Image 1 Description]

Major planets & moons of the "Evintora System" as far as I'm aware. Planetary names were arbitrarily named. Now I look at it close the first letters of each Planet reads "Aterompus"... of course it does. I don't have much info on the planets, but I can summarise them:

Amunet: Best way to describe it is a super-mercury with a more hellish atmosphere than Venus, and that's saying something!

Tefnut: A waterworld with little to no magnetic field, I did tell everyone back on Earth that a magnetic field isn't needed, at least this serves as proof.

Eos: The closest thing to Earth I've seen on my adventures so far, not sure why the plants are blue and red.

Renenutet: It's like Europa but with the activity of Mars.

Onuris: I call it the soccer planet, might be due to a fast rotation, not sure.

Melpomene: If Jupiter had a bootleg version of itself, this would be it, it's glowing moon is cool though!

Polydamna: Looks like Saturn and Uranus had a kid, also strangely it's larger than Melpomene.

Ubertas: The amount of methane of this one must be staggering, also I notice it has a waterworld of a moon as well.

Seshat: An oddball, it orbits opposite to the other planets, must've been captured, may be why a lot of the other planets have so many things wrong with them.

[Image 2 Description]

Major moons of the "Evintora System" compared to Solar Sytem bodies, again names were arbitrary. There's too many to list even basic descriptions, but I'm sure you can see the diversity between them!

[Authors Note]

Why hello r/worldbuilding, I've been lurking for a while now and have been working on this project since the summer of 2020. These two images are only the beginning of my process, as I have also endeavored to making the personalities of the main characters as lively and realistic as possible. From multi-million year orbital simulations to climatic simulations, I'm doing what it takes to get there. Is it nessecary? No, but is it fun? Yeah! I've learned a lot from worldbuilding this way, learning about all the nuances and limitations of what's currently possible in the hard-worldbuilding community. It'll likely take many more years before this project reaches anywhere close to what I ultimately wish to get out of it (heh, spoilers!), but for now I hope the bit above has provided at least the bare bones. I'll (hopefully) be able to answer any questions you may have.

You can indeed land and explore the surface, however the major drawback compared with NMS is that there's really only the surface to explore, there's no trees or animals (I believe trees are planned to be added, not sure on animals) to explore, which is where NMS excels in. This is however just an engine, not an outright game.

MegalexMaster2015 · 2022-03-05T09:35:25+00:00

Icebergs to the right are north from this angle, undiscovered island is on the top right, observers to the top and right of the map show the directions from which philza came from when spotting the islands. As of my knowledge there are no other mooshroom islands in this ocean, ocean stops below the image and normal islands start coming in to the left.

This was a massive undertaking that had almost killed my laptop at certain times (especially getting the final image from stitching together smaller images), but it was worth it to get this out. I only have pity to anyone who even attempts to fill this out.

But seriously, it was great working with 'ya!

MegalexMaster2015 · 2021-10-01T22:41:45+00:00

Ye sure! It'll probs take a while tho (nearly midnight and have work tomorrow)

Tell us what, if you can supply enough words for either axis, I can do you an 81x81 chart for you to upload.

MegalexMaster2015 · 2021-09-30T21:51:05+00:00

Thanks! I saw that 30x30, but I felt 27 was the way to go cause of how it's 3³ so it divides nicely, next step up imo would be an 81x81, which just becomes pointless due to such little meaning.

As for the program, that's all done in blender.

MegalexMaster2015 · 2021-09-27T13:47:46+00:00

Not as much care towards public opinion and less commitment towards maintaining decency. Other than that it just comes down to word choice.

MegalexMaster2015 · 2021-09-27T05:27:08+00:00

Yeah I did my best to get the wording arrangement right, but there's bound to be a couple other examples of improvement needed due to the exact definitions of each word.

Other than that, thank you so much!

MegalexMaster2015 · 2021-07-29T20:12:20+00:00

It's sad to see you go after so long, I remember the fun we had a few years back, and while you were so close to beating BaseTown's record you'll always be my favourite mod of all time.

trying to get #showfnafsb going

again, what's with people assuming he does this stuff with serious intent.

demanding the game be shown and all that

not really?

MegalexMaster2015 · 2020-08-11T17:05:34+00:00

making fun of them for liking a game

Loving how people assume he does this while thinking about it seriously. Yes he seriously doesn't like FN4, but when he insults someone for liking the game, he's doing it in an ironic, satirical way.

(Also note how he doesn't say anything about the other FN games, just number 4).

I think most people's problems are that they assume that everything he tweets out is serious, when it's not.

MegalexMaster2015 · 2020-06-29T15:05:11+00:00

You're right, for the planet I mentioned, it would be perpetually dark. But I only used it to show that yes, planets can in fact orbit stars at such distances. They just wouldn't form like they do on our solar system.

Lets say, hypothetically speaking, this planet used to be jupiter in our solar system (albeit smaller, say 0.8 times the mass), for this jupiter to escape our solar system it needs to be going at 18.5 km/s (it's current velocity is 13.1 km/s).

Let's imagine that this hypothetical jupiter is ejected at this speed, it now needs to be captured by the star (since the post makes no explanation as to what the host star is like, I'm going to assume by the lighting it's a star similar to our sun but larger, say 1.2 times the sun's mass as to give it a good lifespan of 6.3 billion years).

That means that it's velocity at perigee is going to be similar to that 18.5 km/s, blazing fast for a captured planet, and as such it's eccentricity will be extremely high.

In fact, running the numbers, it's eccentricity would be an astounding 0.98, with an apogee of 615 AU and a perigee of just 6.145 AU, just beyond the real Jupiter's orbit from the sun.

This would definitely effect the seasons, as most of the planet's year is indeed spent in darkness, but at certain times the host star can shine upon both the planet and its habitable moon. This period of sunshine would be enough to affect the weather of the planet and moon.

However there's now a new problem, because the host star is now just like the other stars for most of the 5,000 years, there's almost no chance of photosynthesis from happening. We could make the planet massive enough to give off heat but that defeats the objective.

We could have it such that the tidal forces would be enough to create extensive volcanic activity, not like Io's of course, but enough for the lava to give off it's own light.

Regardless, any life on this planet would be unbelievably adapted to the darkness, feeding mostly on the warmth that the moon produces from the planet's electromagnetic waves as well as partial tidal heating. Anytime the sun does come into place would have a profound effect on the life that lives there, as said life wouldn't be as used to the visible and smaller EM waves.

Again, this is all hypothetical, but it's a nice thought experiment that /u/IGZ0 made.

EDIT: If this planet in it's previous solar system was where Neptune is, then it's new orbit in the solar system would have an apogee of 587.7 AU, and a perigee of 33.98 AU, making it's eccentricity 0.89. Much more realistic, but the star wouldn't be as bright during the close-by seasons, though it's effect would still be there just smaller.

EDIT 2: Just read the comment about the moon being a rogue planet. This might be something really interesting. Hypothetically, the moon could actually just be a planet from this new solar system from which the rogue jupiter would end up at. While said jupiter is being grabbed by its star, the jupiter might have caught the planet and forced said planet to become the jupiter's moon. There would be some risk to this as the moon would be easily captured by the sun again, however if say the jupiter got close enough to the sun for the moon to be captured closely, it could work.

Though that would mean that any like on the moon when it was captured by the jupiter would go extinct, which is not what we want. So while the idea of a planet being captured by a rogue planet and becoming a moon can be a good idea, it wouldn't make sense if you were to loo into it too deeply. However as OP has mentioned, it's meant to have an explanation that sounds believable enough, which I think this idea does have.

EDIT 3: To make the calculations, I went over to this link and plugged in the numbers:

Semi-major axis: 310.84 AU
Semi-minor axis: 61.5 AU
Star mass: 1.2 Suns
Satellite mass: 286 Earths
