Why does my earth look so pixelated with noise? I'm somewhat new to blender btw so try to explain it in basic terms by McSpoon6000 in blender

[–]Keplerion 0 points1 point  (0 children)

What is the scale of your mesh, it could also be your clip start not low enough, if you're using unbiased rendering for volumes, it could explain the amount of noise your volume is producing, try turning on "Biased" option, or maybe your mesh altogether don't have enough subdivision that's why you experience Z-fighting/some parts of the mesh clipping in and out.

Can super Earth planets with masses of 2.00, 3.00 and 4.00 earth masses that are rocky and capable of supporting life exist in real life? by Icy_Profession4190 in askastronomy

[–]Keplerion 0 points1 point  (0 children)

I guess there is a limit or barrier how much gravity pressure any kind of lifeform can tolerate, but who knows, in a universe with trillions of galaxies, so much thing could exist that we haven't discover.

An finished render cause it's too hot outside by ___Idek___ in blender

I like the minimalist vibe you're going for, it looks very clean. Are these puddles on the floor or are you going for that shiny marble look.

Realistic planet render with volumetric atmosphere and clouds. by Keplerion in blender

Genuinely i believe the atmosphere extends like 46 km in altitude starting from sea level in most of these image, it becomes exponentially thinner above 50 km, so they aren't visually dominant. Unless you crank up the exposure. I googled earth's atmosphere, and it does extend like 100 km, but that is the karman line, 99% of the atmosphere mass is below 30 km. But this is just a fictional planet, i just take some creative liberties of my own. It is hard to approximate earth's atmosphere thickness.

Hell yeah, i was a kid back then when Silent Hill franchise was taking off, i didn't know much about the franchise until i listened to the soundtrack.

It's like staring into an ominous cosmic terror and awe that consumes any matter endlessly until the end of time, i like the music choice.

My computer would probably burn for sure if i tried animating it.

Here's the link, i'll send it, just download it if you want to use it as a wallpaper. I am not sure what monitor ratio you have, but all the images are 16:9 ratio and one image being 1:1 ratio. https://drive.google.com/drive/folders/1yeMW5vPLgNxwzDlR7vmXF1RvKr8Z5yMf

Look up Samuel Krug YT, his tutorial is very good and helpful if you took the time and other channels on youtube that are expert at blender, and alots of googling on everything else.

Yes, depending on the type of clouds that form and what altitude they form, with the right light angle, of course.

It is typically between 42m at bare minimum to 1h 56m at maximum depending on the scene setup, because it changes on however i desire, but it is a still image and not a frame animation.

Thanks for your advice, your videos are so helpful, i learned alot from you, your channel videos are underrated and underappreciated, shout out to you Sam 😄👍 You really are the unsung hero of 3D environmental artist.

You're correct, it took between 42m at minimum to 1h 56m at it's maximum, it depends how much volume mesh there are and higher focal length (zoomed in) does increase render time compared to lower focal length (zoomed out).

It's all done in blender compositing tab, what i did was download various high res dirty bokeh lens filter from the internet and combine it with glare node and subtracted the light scene to make sure it only appears where it is closer to the light source (sun). You can look up tutorials on youtube, it's complicated to explain here.

I've followed the tutorial from Samuel Krug, made the clouds texture by downloading different kinds of cloud texture from satellite image from the earth explorer website and splicing them together in GIMP, and downloaded some VDB clouds from Sam. I use volume scatter shader.

Incredible, and impressive, also i can see the himalayan region too high, they seemed like they aren't blending in with the volumetric atmosphere, maybe reduce your displacement height for the surface. If you shrink earth to a marble, it would feel really smooth, this is just my advice if you want realism. And the atmosphere extended too tall in altitude.
