Hi All,
This image has been rendered with quality @ 1.25, detail blending 1.25, GI 3/3 and AA 10.
The high-quality was necessary to render the tiny fakestones and other details smoothly.
Atmo-samples were 96 and softshadows diameter was 10 at 30 sampes.
Resolution is 960x1280 and the rendertime on a quadcore Q6600 was just 12,5 hours :)
The tgd is quite similar to one of my latest canyon-images and those took nearly 50 hours on each core, so I'm very happy with the speedup.
The black areas are probably due to too low GI quality of lighting on heavy displacements. I still have to test that by the way.
C&C welcome, thanks for stopping by.

Wow impressive, and so realistic.
Is it the version that already supports multithreaing?

Thank you :) and yes, this has been rendered with the latest update.
Amazing work here TU, really really impressive. Can't wait for more. 8)
Great shapes. Very realistic in shape.
Thank you guys :)
I've tested higher GI settings to determine if GI is really responsible for the black areas and it seems it isn't.
I've rendered crops with GI up to 6/6 and later also with GI surface detail enabled but all didn't improve it.
Does anybody have a clue?

Really nice surfacing work. Unfortunately I don't have any idea of what would cause the black marks other than the occasional displacement tearing I sometimes get when using the redirect shader.
good start !
As for the dark spots i've seen comparable effects with power fractals used
for coloring,just a thought.
Amazing work Martin!
Are you sure the dark spots aren't the base surface layer showing through, after perhaps being switched off or darkened?
Thank you guys :)
Well Jim, I'm not so sure about my case anymore so you might be right. I will have to check it out to be sure.
Like I said I often have troubles with coloring the surfaces.
In many cases the chosen colors do not have the same result when rendered.
All probably because of lighting conditions but nevertheless I find that hard to cope with.
I'll check out your suggestions when I'm back home. Thank you for your input :)

Glad its not just me when it comes to choosing colours and then finding that they render as a completely different colour to the one chosen ;D Thats about the only thing I miss from TG 0.9XX At least if you chose a colour in that then it rendered in the same vague colour range >:(

I think that 'lighting' and shadows plays a major role as to how the color will be perceived.
I realise that, its just that it seems to play a damn sight bigger part than it did in V0.9 If you used a colour in V0.9 at least it rendered sort of like the colour you chose, In this version most of the time the colours render nothing like the ones you chose and it makes it rather difficult to get what you want.
Thank God it wasn't just me and you said something. I have wondered why the colors I chose come out so different in the preview window
and in the actual render. What to do...now..?

I have the exact same thoughts :) thought I was the only one suffering from this problem, also because I'm slightly colorblind.
I also experience that the finished previewrender differs quite much in colors compared to the final render.
In overall the colors become a bit fluorescent-like to my opinion.
Don't know where I've read it but someone told here he misses the randomize colors function from TG0.9x. A similar function would be very nice to see in TG2.
But all in all it's just a matter of trial and error and thus lots of exercise...

You don't know how happy it makes me that someone else has the same problems. I thought it was just me too. I realy noticed it when I did my Scafell Pike render http://forums.planetside.co.uk/index.php?topic=2734.0 (http://forums.planetside.co.uk/index.php?topic=2734.0) I used a photo of exactly the same view as reference, opened the photo in Photopaint and sampled RGB colour values from the photo to use in TG. I started doing this, and the preview screen top right looked nothing like it should, so I tried it with a quick render, still no better, so I did a few crop full renders and they looked even worse. In the end I had to do it trial and error. Took me twice as long to surface the scene than it should have done >:( I'm not talking the colours being a "bit off" they were all completely way out, nothing like the colours I chose. Alright, if I chose a mid green, the colour I would end up with would be "A" green, but it would be either a huge amount darker / lighter, and not even in the same tonal range..... And another thing.... ;D
Rant over

One reason (among many) why I like Art Rage is the ability to create a color palate from another image. That would be useful. But, still the palate to final render transition needs to find some happy way to mesh. And maybe further understanding would help.
You mean you can sample colors from an image and the same colors will appear in your render?
Something similar would be great. Depends on whether you can predict how colors will result, is that possible?
Sort of. In ArtRage, you can sample an image and then that image becomes your palate for using the exact same colors as the image to color your render. This would mean a modifiable palate, which might be more work for Planetside (more work for Planetside isn't something I prefer, at this point). If it isn't that difficult, I'd love it.

The chosen colors are represented properly in the render. I would say it's more a matter of not properly accounting for the effects of lighting, atmosphere, etc. The difference between TG 0.9 and TG2 in this regard probably comes down to 3 factors - Global Illumination (not present in TG 0.9 at all), different atmosphere model (an improvement over TG 0.9), and a different tone mapping function (so-called "soft clip", although I believe it is still similar to TG 0.9).
In any case I would not expect drastic differences, nor do I think it is really that much different from TG 0.9. One other factor that may actually play a greater effect than anything is that the *method* of choosing colors is completely different now. The full color palette, as opposed to the little sliders, changes how you will pick colors a lot. The swatches are also larger now I think. Not to mention that it doesn't show a range of exposures as it did in TG 0.9. Enough differences anyway that it could be having a notable effect.
Actually, one thing that just occurred to me is that TG 0.9 had a way to adjust both the render gamma and the GUI gamma. If you adjusted the GUI gamma I believe it affected the surface color previews accordingly. I'm not sure TG2's render gamma has the same effect, or even whether it should, but that might be an additional factor as I know a lot of people turn down the gamma to get a more saturated look.
That being said I do think colors render as they're "supposed to". I too have had trouble picking the exact right colors, but I think that is partly just because we have unrealistic expectations about real-world colors. In the specific case of sampling from a real image you will run into a lot of difficulty because of specific lighting, atmosphere, camera, white balance, and other factors. I don't recall it being all that easy to match colors in TG 0.9 either, nor do I think it is particularly effective in other similar applications.
Still I agree there's room for improvement, it's just that the current systems work well enough and give you all the power you should theoretically need. Anything more would really be a "helper" type of tool. Something to think about for the future...
