Mountain scene using redirect shader.

Apparently all over the surface of the mountains, Kevin F. I can see lots of lateral displacements on them.

I think the planet in the background could be better surfaced, there appear to be black patches which look like they aren't using any shader information, try using both high/low colours(not black for the low) on the base fractal of that planet and add consecutive layers on top of that, which only check either high or low colour. The lower-most shader should cover the surface entirely so as not to leave gaps, such as I see here and the higher layers should apply only one colour over that base.
Possibly, though, these are shadows? The planet does seem to have quite excessive displacements.

Well I'll beef hooked if I can!
Seriously, please can you point them out to me. I must be missing something.

Don't!

Any part that overhangs any other lower part of the terrain is making lateral displacement with the redirect shader.
Most perceptible at the far right hand side, you'll see a kind of 'hook'(not a beef hook) on the top of a peak. It is displacing across the way, not upwards. This effect is completely covering the entire terrain, granted, it isn't very well controlled and distributed but it's very apparent across the entire surface.

I think the scales are quite off for the redirecting fractals, far too small for feature/smallest scale, making it excessively jagged all over.

* I did.

dandelO- Thanks for the comments and your help. Regarding the mountain, I think we are looking at shadows. I could probably remedy any questions by softening the shadows a bit and applying an ambient light (a fill light) using a second sun.

Kevin F.- Thanks for the welcome to the forum.

As a newbie, I welcome your comments and criticisms. Now that I have calmed down a bit, I will be picking and choosing my renders more carefully and I will definitely be studying the artwork of others on this forum more intently.

I am working on one more scene using redirect shaders for this current cycle but the scene has, so far, proven to be a bear to render (I stopped it after six hours). So, some tweaking must be done ...

I meant that the dark patches on the second planet might be shadows from mountain displacements on that planet, as opposed to my original thoughts about lack of colour on the dark patches.
There appear to be pink and red shaders but then, strange black patches that look like they have no colour being applied to them.

dandelO

These red parts in the original image seem to have no colour, I thought it was because of lack of low colour or too high contrast in the fractal.

It's possible for planets to have black spots like that. Just look at Jupiter's moon Io.
They just issued a tornado warning and said to stay away from windows. Does that mean I can't use my computer?
