Both methods are very useful to know. Using volumetric for the atmosphere makes it look amazing, great light scatter effects for close up shots too, however it can be hard trying to indirectly control how it all looks. Meanwhile your method saves a lot of render time and noise, so its probably better for animations, and is also more artistic being able to alter the look more directly.
Hey Bob, love this new approach, especially the atmosphere... though, I should point out that for some reason, most people seem to blame the UV sphere for the pole pinching, when in fact its peoples lack of understanding about the image maps you are using from NASA... they are called equirectangular maps and are specially created to be used with UV spheres, you just need to use the map with the Environment Texture node, set it to Smart and then set Tex Coord to Object, bingo, no pinching and no phaff :)
you know, I noticed the pintching in the poles in the blender guru tutorial. my fix is: I made a perfect quad sphere and shrinkwrapped the uv sphere on top of the quad sphere. worked pretty well. I did this cause I had already done the full tutorial and it was the easier way for me. edit: your method is really goos, I followed your tutorial alongside blender guru's and what I`ve noticed is: the weird effect that occurs when clouds instersect mountains and it kinda clips is more noticeble.
the Generated Coordinates trick is genuinely great The pinching can also be fixed with a Cast-to-Sphere modifier. But really, the best method is to just directly use enough geometry from the start. Or you can start from a cube, subdivide that a bunch, and turn *it* into a sphere. There is an addon for that too I think. One that ships with Blender, adding a bunch of new base objects including that
Bob you are amazing! I really appreciate you showing us your own way of working! I saw the amazing looking sun in the trailer of the end is mye and I would like to know if you could show us that too? :)
Some comments: 1) Some footage from low orbit shows the atmosphere in a very white glowy fashion even if it fades to blue nothingness. 2) Aurora borealis only covers the "illumination poles", so might want to mask out that, and maybe animate it as well. 4D generators for the win, modulate everything with time. 3) Not sure if it applies anymore, but in the past I've had issues with sphere projection and ended up using environment mapping (x * -1) instead. 4) If you need infinite resolution without the cost of infinite geometry, say for proving flerfers wrong, there is the option of doing geometry nodes and a single point with a radius. It has many limitations, like can't be blended/overlapped/displaced (most likely), but it's nice to know what other venues can be available. 5. There was a VSE optical lens flare addon (channel cgvirus) years ago that was immensely cool to play with. Not sure if it still works or if better ones have arrived since. 6. Using fresnel is technically wrong since this isn't about specular reflections. You can make it work of course, but I'd probably start with layer weight/facing or a trig function on that which spaces it out more evenly for easier tweaking.
@@BlenderBob Which is why I said "technically" 😁Facing is already normalized 0-1 and works the same for all normals, whereas fresnel isn't and may produce erroneous results when looked at from inside/below (snells window effect on backfacing normals). If someone else use my stuff, I just think it's better to have them go "makes sense" rather than "why". Countless times when I used fresnel did I end up in trouble due backfacing faces. May not apply to your like of work of course.
What would ala be sick if we could add Aurora Borealis and Aurora Australis as well. Thats something I've never seen as well in these shots. I made the closest d material have some translucency so the city light texture would influence it as well. I didn't need that setup you talked about. Though your setup with the fading edge using layer were GHT is really great. I would make that a node group since it seems the same setup is used a couple times, that will make it easier to adjust it in each setup
Nice work. Question: now if I want to fly a spaceship in orbit of this beautiful Earth, I get a big crispy shadow on the clouds layer. Which, I imagine, would not be the case in reality, due to massive distances and diffraction in the atmosphere. How do i get rid of that shadow ?
Thanks! That mush be a hell of a big ship to cast shadows on the clouds! What you could do is change the radius of the sun light. The bigger it is, the softer the shadow.
@@BlenderBob haha well, if you look at the comparable sizes, it'll probably be a size of England :D but the intent of it is to be 150m long, and have an Earth curve horizon in the background, in the perspective. Doing realistic distances would crash my blender (it already crashes when I render Earth at >960x540). Also another annoyance is the reflection of the spaceship engine flames in the earth ocean :) I tried to make atmosphere more scattery, but then it blurs out the continents into a bluish/grey fog.
Hi Bob! Great job! I would really like to see your blend file to study it. Is it possible? I would be very grateful, it will help me understand Blender and boost my learning (I'm taking courses, following every tutorials and after 6 months, I learned a lot but the way is long). Blender for me is a serious thing, not a toy! ;)
Thanks! I wish I could help. It was donc on remote from the computer's office and for security reasons we can't move stuff in or out. We don't even have internet access on our machine. But if you follow the tutorial, both of them actually, you should get the same results. Everything is there
Ok, no problem! Thank you, I really like your videos, your channel. I completed the great Blender Guru tutorial and got a good result, but I needed the help of my "friend Photoshop". But I'm still having trouble following yours :( which I found fantastic for allowing greater control of the result, generating countless possibilities). Maybe I can do it after watching it 100 or 101 times ;)
Very cool version! I remember the initial tutorial he did years ago, i did the tutorial but used a different render engine. I was super nice! Ps i believe the northern light is not that green edge you showed near the end. The northern light is only visible around the poles of the earthe due to the magnetic forces, i believe they are ions which enter the atmosphere. Guess the green edge is refraction of light. But I'm not sure about that
Really nice work BlenderBob :O) there are others who did earth tutorials before Guru's recent one, and its also pretty good, its by TH-cam'r Ryan King Art may 2021
Can you please reconsider doing the earth tutorial from scratch over again? Since Blender Guru made his blender changed texture resolution limits and now my planet is messed up and cannot be corrected for some reason. I have to start over.
I'm afriad that I am stuck at the new Shadow Side handling. The video doesn't show the entire complete node tree in that section. Blender Guru uses a Math Multiply with two values. Your nodes use a Mixer shader with a Factor, so three inputs. You put the SHadow Side Mask into the Factor, and the earthlight and mixed noise into the lower shader input, but it never shows what is connected into the upper Input on the Mix Shader. Any help appreciated. Good video. Thanks.
I would like to know how it would be possible to create a map similar to this but with the possibility to zoom and have a detailed map scale like google maps. for rpg project
Awesome, how could I add the countries as separate polygons on earth? Like if I have a vector file with all the countries? I cant find a way to import a vector of a map of countries in Blender and turn it into a sphere. I can change the imported vector collection into a mesh collection but don't know what to do next so taht I still have separate poly for each country but as a planet :/
@@BlenderBob thank you for the answer. Unfortunately this doesn’t solve my issue because then I loose the separation of the countries and I need to have them as separate polygons for each country
Instead of changing the emission color with color curves, wouldn't it be better to just multiply them by a color? Could use the blackbody color node and pick something like 4000-5000K Likely not that big a deal but at least to my eyes the version you did here has a pretty ugly yellow, and the "actual" color is likely to be close to a blackbody radiation one anyways. Could even try to add some noise to the color temperature to get a slight variety of colors, although curiously, in that emission map, it all looks pretty similar. I suspect that might be due to when the image was taken though. It's not unlikely that these days cities look like they glow with a much colder light, as they switched to white LEDs
Hi BlenderBob, can't get past the method you use for the roughness with adding the principled bsdf for the orange glow. No matter what I do (also tried with colorramp) it all looks orange but not with the result I see you achieve. Are you possibly willing to share your blender file? Or do you have a discord server to not so publicly share stuff... email is also good AFAIAC ;-)
Didn't bother to listen to the man then? Andrew released his own Planet Earth tutorial just the other day so Bob was just being polite, y'know, like a normal decent person.

@@BlenderBob I understand and thank you for your answer!
Amazing for Science Fiction! To be like real life though it needs to be completely flat, with a vast ice perimeter holding in the level water
It’s actually a Möbius strip
you can try this to fix the bending by scaling image up and down and set method to bicubic. it will blur the bending line.

Of you use adaptive subdivision, it will subdivide according to how much space it takes on screen so on only generate the needed polys.
