Re Plate Tectonics.
Plate tectonics has more to do with the interaction and heat transfer between the inner solid core to the outer liquid core creating convection cells in the surrounding mantle like a rolling boil in boiling water. The Continental and Oceanic crust move on top with the heavier oceanic crust being subducted under the lighter and more buoyant Continental crust. Water also gets transferred down in subduction zones and will reduce the melting point of the rock in the crust. In the end no heat, no energy, no plate tectonics.

See the post above yours ...
Take a look at this NASA page about Cassini and Enceladus.

Now remind me, am I looking at an image from a space probe, or in-game screenshots from Horizons?
Seriously though, if it gets that hard to tell apart a planet in Horizons from real world space probe images, we can safely say "Frontier have nailed it!"

In my eyes they've nailed it ... and that's good enough for me.
Just stunning. Thanks so much for posting that and to the devs for taking the time to do that stream. This really is truly extraordinary work guys. I'd love to have seen a scale image of the SRV in each of those video clips but my guess is that it would be TINY. It's truly mind boggling how much landscape will be there to explore. Even if we just had one large planet it would take years for all of us to cover the entire surface ... and there's going to be billions of them. It's insane! (but in a good way). Surely the odds of there being a formation out there somewhere that looks exactly like the face of the Mona Lisa must be pretty high? Anyone care to do the maths

amazing stuff, I was a little worried about the look of the surface, but the devs have blown me away, its way beyond what I expected.
The LOD jumping is a bit jarring but I can live with that and once on the surface it shouldn't be too problematic
Now I would like to see some close-up surface stuff and some gameplay, please............

1) We don't use an angle of impact no, however each crater is unique so you can expect to see the ridge of the crater be a non uniform height so you will get realistic variation which should help imply direction of impact when you look at enough craters
I may be late to the party but want to chime in here: it is, like, ultra-ultra-ultra-rare that an impact happens ever at a 90° angle - yet almost all of them are circular, and that is because the crater is formed by the impact shockwave, which spreads equally in all directions even at very shallow impact angles. So it is really not even needed to consider them in the first place.

yep, another good explanation here:

Elongated impact craters do happen (see below) but the above article explains why the vast majority are round.

Howdy folks.
I wanted to try and explain a little more about our system to hopefully lay some concerns to rest. For a plate-based tectonic system on a planet, a large enough temperature gradient is required to have a phase difference between a relatively thin crust and the deeper innards. That temperature gradient can be driven by things such as gravitational compression on a large enough body, or gravitational stress from orbiting a much larger body closely.
So yes, smaller terrestrial worlds, unless under rather specific conditions, will likely have crustal plates too thick for a tectonic mask to make sense. However, tectonic interactions is not the only way in which surface features can be formed.
Asteroidal impacts can create shockwaves across an entire planet's surface, deforming the crust in interesting patterns. The formation of a planet from the cataclysmic merging of two planetoids would liquify most of the material, but there is the chance for old solid outcrops to survive or influence the shape of the resulting body. Gravitational stressed can be enough to drive volcanism which forms mountain ranges on a surface. An event in a planet's past might alter its orbit from the previously stressful one to a wider/eccentric one, solidifying the new features. Impacts can cause rifts, ridges, and hill ranges as well as the expected crater.
To get back on topic, our 'tectonic mask' system takes into account various factors from Stellar Forge, such as:
expected gravitational stress / sibling and parent orbits
gravitational compression heating
material of the planet
size of the planet
tidal locking state
expected core, mantle, and crust temperatures
viscosity of mantle
deformability of the materials
age of the system
expected frequency and magnitude of meteorite collisions
nearby sources of regular debris
and more
The system creates masks for areas of potential crustal deformation activity. Those areas may reflect the shapes and activities of tectonic plates if it's sensible for that particular planet.
It may reflect other shapes if the sources of those deformations isn't bona fide tectonic activity. The same system is used for large and small planets, and adapts as it needs to.
We ended up calling it the 'tectonic mask' because it's short, snappy, and places the same kind of visual features (even if what physically would have generated them might have been different).
TL;DR "tectonics mask" is a shorthand way we've been describing all the regions of crustal major deformation from a variety of sources.
(p.s. similar thing with the limestone material on an oceanless planet question. Limestone is a short, relatable name for development compared to "calcium carbonate rich analogues"

(posted in wrong thread before.. so repost)
Guys you are doing an amazing job! Well done to the whole team involved. It's funny actually to think that a game about spaceships could become one of the most scientifically grounded and interesting studies on natural formation in a computer game. But there you go!
Looking forward to the next installment and to how progress is coming along. The canyons in particular are really breathtaking and the other details mentioned and demoed are looking terrific. Surfaces are really solid (I think around 14.35 in the video, where the cam gets close to the outer edge of a crater- is the only place where the perlin noise looks a bit too perliny noisy, the inner part of the crater looks great though).
Can't wait to see where things go next! Awesome stuff and very very inspiring.
Cheers!

Many Thanks Anthony that's an extremely detailed and very interesting post, it's the sheer level of that detail that you're going into which makes this whole process seem so amazing to me, top stuff

We need more videos!
Releasing the Beta would also be an acceptable solution!

Nope, I'd be more than content to see nothing more until release and then be wowed.

Is it too early for a Tinman beta release date prediction? Are you still on 100% on that?
I'll open the guesses with 17th November...
