This question is from more of a creative perspective: Will custom planet maps still work?

Likely yes. I expect you'll still be able to import your own textures.

Q1: Are you guys going to add shock waves when something hits a planet with an atmosphere?

Here's a reply from Thomas, the guy developing the code for the SPH (smooth particly hydrodynamics = 3D fluid physics):

"Speaking from a sph view...

About shock waves for atmospheres... a Jupiter would likely be simulated as one large atmosphere and a planet like earth would certainly (using SPH) show shock waves through the ground. The atmosphere is however tiny compared to the rest of earth, so that would have to be simulated differently and it would hardly be sensible to directly calculate those effects."

Q2: Will it be possible to start a solar system using fluid cloud simulation and a supernova? (be nice to leave it for a day and come back and see a planet like earth in orbit  ;D )

Also from Thomas:

"The leave and come back later to watch a nova remnant starting over, that is very unlikely. Both because (as far as I know) not even a large collection of supernova leftovers will be right for a gravity collapse again and because we do not simulate stuff out of view at that detail level, it would be a no.

It is my understanding the cloud would have to exceed the critical mass for its current energy level and that would either take a very high mass at a small area or a very cold gas. Neither of which I believe is present after a nova. On the other hand, it would be interesting to show a nearby nova pushing to a large cloud and compressing that cloud to the critical density at which a collapse starts."

We're making no promises here... just being open about our internal commentary. He wrote these comments up for us and I asked if it was okay with him to post them here.

Dan or Thomas will there Be lighting and volcano's on planets? or lighting for gas giants?

I wouldn't expect that in the initial release of v3... maybe in a future update.

Eric, our astronomer, put together a short video of our first pass at stellar evolution leading to a supernova explosion (as it was edited out of the Unite video)... Enjoy!

And because this is simulated and not just a canned effect, look for all kinds of exciting variations and mixtures of this and other features to come...

one last one. Will the supernova destroy planets and near by planets light years.?

Loved both videos very nice work Giant Army! CAN'T WAIT FOR THE RELEASE!!!!
I have 2 questions though:

If an object is sucked up by a black hole will there be an animation rather then just disappearing?

and

I loved the supernova effect but I was wondering will there be a Hypernova effects?

Good question. We're not sure yet, but we agree this would be awesome. We'll see...

If this were true...

It would make your video impossible.

How does that affect two random planets in some far off star's system?

Per the video, moon size planet colliding with earth = result in video, formed destruction of both bodies.
Per the Giant impact hypothesis, mars sized body colliding with earth = moon and a earth with water and an atmosphere.
That depends on other factors than simply their masses, like their relative velocities and the angles they collide at.

That being said, the GI hypothesis has many glaring holes, which of course doesn't stop it being the favored answer by the consensus of science.

Hey Phinehas, been a while.

Anyways, I agree with you here since a head on collision would result in the total destruction of both. If anything, and from some simulations I've seen, it would have been a glancing blow.

Unfortunately this does not answer my question, as it shows what happens when lots of tiny asteroids hit the planet. I want to see what happens when two planet-sized objects collide. But still, it's a great video. Can't wait for ubox 3.

I think everybody here wants to see what happens when two planet sized objects collide. :)

Anyways, they may be trying to leave that as a surprise for us to find out or they aren't ready to show it to us yet for one reason or another.

I was wondering if collisions with larger objects would lead to chuknks and pieces breakin off. Perhaps triggering changes in the atmosphere. For example of a large object hits earth a lob of molten rock would break off and the large object would merge with earth and because of the extreem heat it could cause the earth to become a venus like planet. Just a thought. Temerature readings goldilocs zones and other facts like taht would be nice if you wanted to model a perfect human supporting galexy. Good luck guys!
