Hi peepz
This is a crop of a render I've been working on for almost a day. It took ages to fiddle with the strata settings and to make it all look good at the target rendersize and detail, which will be 1600x1200 @ detail 0.7 AA6 and without GI. As in my last fake stone image I've used a 9 sun lighting-array (see node screencap). Rendering this crop took about an hour.
As you can see I've put circles around some problem-areas where the displacements are messing up the geometry. It often happens that using the displacement-shader can create very distorted steep slopes. At some areas this has happened. I presume this can be solved by tweaking the strata tilt direction. So this is something I still need to try.
Anyone else suggestions?
I've also tried to create overhangs using the redirect shader or using a powerfractal on steep slopes (like in Haroon's canyon impression). Creating the overhangs isn't that much trouble, but stratifying (is that english?
) the overhangs didn't work at all. The only results were very distorted steep slopes with spikes all over it.
I think it may have to do something with compute terrain node before using the strata-shader, but I couldn't figure it out. I've been trying gradient patch size from 0.1, 1, 10 to >20. All with no effect.
So again, anyone with suggestions?
Ok, further on...I'm pretty happy with the results so far, but as I mentioned it's a WIP so here are the things to do besides the problems stated above:
- Increasing size of small stones on steeper slopes and add slightly more detail.
- Add more detail and slightly more displacement to the bigger stones. --> THANKS Frank for your crack-technique, it's easy to work with!
- Add dried mud/crack texture to the riverbed (bottom right).
- Add shrubs/trees.
- Working on colours, because they look a bit monotone/bland right now.
Well, that's it for now, let's get on with it
Please let me know what you think about it and I'd really appreciate it if you have any kind of suggestions.
