100% procedural, full scale, earthlike planet

Thanks for your great feedback.

Actually, that was my original goal: just to say thank you and give something back. With every step of development my project became more complex but also more confusing. There are currently different versions, with different problems and solutions. The node-setups are a huge mess and the handling of the relevant parameters is completely undocumented. As described elsewhere, due to the grown complexity and the already spent time and effort, I wanted to draw a line for the time being. The renderings I present here are the best I could get out of the status quo and are not necessarily representative of the craftsmanship of the file itself XD. In the current state, releasing a source file would therefore be more of an inconvenience than a pleasure for me.

I need some distance to the project for now, but I still keep the publication of a usable source file in mind. As soon as my motivation picks up again, Iā€™m looking forward to share my project progress and know-how with the coummunity.

I hope that my thoughts on this are comprehensible for all interested people and therefore I ask for some patience.

Wow impressive stuff! I would love to know how those clouds are created. Any way of making the cloud system publicly available?

I featured you on BlenderNation, have a great weekend!

Thank you Lasse! Yes, there will be. I will try to provide the cloud system here over the weekend.

Deep respect. I love what you have done, the results are very beautiful indeed. One thing caught my eye, the cloud shadows on image 03 seem too long compared to the apparent depth of the atmosphere seen at the horizon.

Thank you for your praise and feedback. I had tried to approach the matter as true to scale as possible:

  • Visually perceivable height of the atmosphere at about 80km
  • Altitude of the clouds at about 2km
  • Cloud thickness at 2km to max. 12km

I assume the shadows are simply due to the planetary curvature, which is not so well assessable in this screen due to the camera settings.

But it could also be a bug in the cloud system. I would not like to exclude anything here. The nodesetup still has a lot of room for improvement.

With such very long render times debugging would be a nightmare. Best stick with what you have, itā€™s wonderful!

So those are some scary render times, but it looks for interesting, so I downloaded your file and thought Iā€™d give it a shot.

I only changed 2 things from the downloaded file. I set rendering to 100% (so full HD) and I enabled the Turbo Tools rendering plugin.

Hereā€™s the result:

That took under 2mins to render on my 3080 Ti.
Will have to play around with this a bit more when I get a chance, thanks for sharing.

Canā€™t believe this possibleā€¦ Hey! This is absolutely mind blowingā€¦ incredible!

Wow, the difference is as impressive as it is frustrating XD. However, Iā€™m very happy to see that the file doesnā€™t render as inefficiently on appropriate hardware as I experience.

On my hardware, with identical settings (but without Turbo Tools), almost 4h are announced:

Thank you for your reassuring feedback!

Thank you for the praise. There really isnā€™t as much magic behind it as it might seem at first glance.

Well, Turbo Tools let me use around 160 samples and for the most part it doesnā€™t even use that many. The 3080 Ti then does the rest, got to love those RT cores.

When using adaptive sampling and denoising itā€™s common that the estimated numbers are high in the beginning.
But probably given the gradient in the sky for instance it might be that this part will need much less sample and adaptive sampling will work itā€™s magic.

Anyway since itā€™s a lot of volume with complex textures itā€™s natural to get long render times.
But Iā€™m sure with a few samples and denoising you can get good results after a few minutes.

But it might not be enough for animation though.

I absolutely agree with you. However, in the case of the clouds, the denoising does not achieve very satisfactory results below about 500 samples in my opinion. If I want quality, I have to suffer XD . So, I guess, as long as I canā€™t afford a better graphics card, Iā€™ll just have to deal with it.

Youā€™re on the #featured row! :+1:

This is stunning. The renders here look like areal/space photography. Great work!

Oh, and since this is some sort of benchmark, on a MacBook Pro (Intel QuadCore 2.3Ghz) the scene as downloaded announces an estimated render time of 12 hours 50 minutes. :sweat_smile:

This is the most beautiful sky I had ever seen in my life.
