Title: Jupiter

Test to get a decent Jupiter.

Very nice indeed great textures and some subtle touches like the mist are superb.

Epic stuff Ulco

Really epic!

But...
I am a little bit ashamed to criticize, but could you get the displacement of the Jupiter clouds smaller? It looks impressive but feels too much.

Impressive! Did you use an image map for the atmosphere? If so, you might want to add some small fractal displacement; there seems to be a difference in resolution between the rocks and the atmosphere. But maybe this is just what you were after. ;)

Yeah, what he said. I thought exactly the same. It's a bit much. Gotta remember that Jupiter would probably be several hundred thousand miles away from the camera in this pic.

No problem, crits are welcome of course. And yes; image map, so I'm bound by its 4K resolution. Sure I can dial the displacement down and add some fractal. Fractal color adjust perhaps, I'll have a go. Renders fast so, it's no worry at all.

Nice Job. Agree the displacement could be downsized a tad.

Well done, looks fascinating :)

I suspect that, if you were that close, the displacement would be about right!

Never been there, myself. The only problem I had was the slight jpg compression artifacts. A little less bumpmap and more procedural displacement would overcome that maybe. i'll have a go anyway.

I'm sure that out near Jupiter is WAY beyond the limit for the inverse square law to make a real difference so shadows (and thus displacement) won't behave as we normally see them. The falloff at that distance would flatten shadows by virtue of the light intensity being reduced by the factor of the inverse square law beyond anything that we see on Earth.

Not that it doesn't look good, I'm just not sure it's scientifically accurate, which I think I may have mentioned before, is something I have issues with....

Great image.

Perhaps you can use the warp shader to deform jpeg artifacts and add some more detail at the same time away.

Amazing!

Two more versions, one with a softer map (no artifacts!).

Beautiful. Hard to choose, but like the last without the big flares.

Agree the bottom one rocks...

Like the last one especially Ulco.
But the composition of the ground in the first one looks a little nicer to me.

Post by: DocCharly65 on June 14, 2017, 09:48:11 AM
I like the first a bit one more because in the second the angle of the shadows in the foreground don't seem to fit the sun's direction so good. In the first somehow this effect isn't so visible.

I'll do a few more foregrounds, renders extremely fast anyway. I myself don't like the first one, also because of the Jupiter fractal color adjust and warping, and extra PF for displacement. It's too rough, IMO.
