A work in progress. The clouds need some billowy tops here and there, trying to figure that out and that icing on the cake, procedural erosion.
Looks like a good start.
Thanks, i'm anticipating eroding it. In the meantime i will fix some other areas.
Looks fantastic so far. Maybe some more dramatic lighting to distinguish the clouds from the rest?
Curious, what did you have in mind?
In your image the sun seems to be right behind the camera. Full frontal lighting so to speak. If the sun would be a little more on the side you'd get some cloud shadows and it would look even more interesting imho.
Btw, are your shadows disabled? There should be some even with the sun behind the camera.
Shadows are there but i will move the sun to have more distinctive shadows.
Cool! Looking forward to it.
I could wait until the next upload with the moved sun but anyway it looks good ! :)

Hello Chris,
I'd advise you not to count on procedural erosion shader too much, it isn't so great as one can think. It can be useful, but it isn't handy and very limited in possibilities.
Moreother, currently it even doesn't process infinite area. I'll add the support of much larger areas later.
And another bad thing. Currently it works with a planar projection and cannot be used to process a whole spherical planet. Although low-orbit views can be achieved with it.
Daniil.
Last I tried it did work on a pretty large area Daniil. ;) But yes, not fully global yet. Still, from a well-chosen orbital view it can provide a still very nice effect IMO.

Thanks for letting me know about this. I will have to come up with some alternative because i still want to create some type of channel effect along the slopes even if it is some noise and warping tricks. As how to go about that is anyone's guess.
Great looking planets.
Much better.
...and your work inspired me :)

Well, yes, for relatively low orbit it can be acceptable.
Here is a quick attempt. Of course better shading work is needed (with optional use of generated erosion maps), and may be also a masking of erosion.
Also it is need to tweak original terrain to achieve a better system of channels ending in the ocean.
Higher orbits will make more noticeable distortions.
Also, Chris, may be for your planet it is better to use some sort of Ulco's technology with using just maps generated by shader and then applying them as displacement.
That is not bad for what it represents as i need nothing fancy, just rather basic patterns perhaps. I understand the ocean part of it where the coast needs more smoothed shapes and some deltas.
Ulco's technology? Did i miss something.

Ulco's rivers (or at least part of them) weren't made by direct processing terrain by erosion shader. He extracted flow map from it and drove it into displacement shader which was processing the original terrain. That is what I know, although he mentioned that things are more complex than just it.
Daniil.
Oh, yes, his river tests.

That is always very good to hear such things.
