This is my first attempt at a planet render. Any advice/thoughts?
>>
Too much bump, not enough specular variations, low res textures, bad lighting, awful "atmosphere"
>>

It's not too good.
Refine your bump textures. If you're using images, find better ones. If you're using procedurals, revise your noise patterns and make them smaller and more detailed. The biggest offender in that is that patch of plateaus up in the top left quarter. That's a pretty big no-no when it comes to planet geology, because it just doesn't make sense to have such large plateaus.
Atmosphere is poorly done. I hope the big bloom effect is due to post-processing. You managed to capture the atmosphere rim lighting, which is a nice touch, however it should extend further into the dark side. Use volumetrics if you have to, because any hack job to simulate scattering just doesn't look the same (I've experimented a lot with atmospheric scattering shaders and found that using volumetrics just produces the nicest result).
Lastly, on composition, you need a few stars in the background to fill your scene more. The planet looks really lonely. Some addition of ambient lighting to light up the dark side of the planet would help too.

looks pretty good, but i would lower the bump abit since its viewed from afar

>t. OP "Butthurt" the 9th

OP here. Thanks for all the comments and advice. I've only really just picked up 3D rendering as a hobby a few months ago, and doing it seriously (actually making shit rather than fucking around with meshes) a few weeks back. Just clarifying that this was a quick slap together and first attempt. Thanks again for comments

OP here, I mixed two Mercator projections of Ganymede and Up. Any suggestions on where to find more high res images for texture?
>>
>>624994
Also send tips on how to make background stars would be appreciated
>>
>>625097
You can find good stuff from the NASA repo. Play around with texture scale as well as rotation and you can get more randomized results.
>>625098
As for this, there are some approaches you can take:
Composite a backplate in post. Render out your planet with transparency enabled, and just add a nice background of stars.
Render with a HDRI. You'll get a full environment of stars, like in space games. The only downside is that the starmap may appear low resolution, depending on your render focal length.

If you really want to go wild, definitely play with procedural textures. Get ready for humongous node setups, but you can achieve a ton of things with them, from planet generation to procedural star fields (as an environment, anyway).

Thanks

Just don't use blender, it's shit.

Love the Bump if it is a moon. The atmosphere is too high or too thin for that height. Besides that, I think it's great.

Thanks! Nice dubs

I am going to be honest, I haven't given any critique on the piece because I am quite ignorant about how space pics are supposed to look like
to me the OP looks fine, but I must reiterate I am clueless about which features would look convincing on a planet when looked from far away in space
>>
>>624986

Looks vaguely like Io. How big is this planetary body supposed to be? Where are we seeing it from? Are we seeing it from the surface of another planetary body and the haze is caused by the atmosphere we're standing on or are we viewing the body from space?

Look at NASA photos of bodies similar to what you're trying to portray.
>>
For procedural stars use a voronoi texture with a scale of like 3000 and put a color ramp after that and bring the black up to like 0.99. That will quickly get you some stars. Then maybe add noise and stuff for nebulas

Nice refutation of the objective analysis of this poster >>624994, oh no wait no it wasn't at all.

Don't you have a blender thread to haunt, you fucking waste of a human being?
>>

Op here
It should look like Io. I mixed Io and Ganymede Mercator maps. The haze was supposed to be caused by the atmosphere we are standing in. Wasn't really trying to get a 'perfext image' was just practicing my skills and asking for critique. Thanks anon
