Title: 2 renders...
Post by: Rich on February 01, 2007, 01:49:43 AM
hey, here are 2 of my latest renders if anyone wants to check them out....

1. A desert scene with low lying thick clouds and some high cirrus

2.A snowy scene

I really like the clouds in your desert scene.  Your small sand dunes look good, but I think it would have brought the image to the next level if you had made some dunes with a larger scale and maybe added a small scaled fake stones shader with low to medium density.  Your snow scene looks nice too, aside from a slightly (in my opinion) too sharp boundary between the snow and the rock.

thanks...i wanted to make the dunes have that wispy overhang look, im not smart enough yet...
and i know about the snow-rock boundary but i dont know how to make it look better :(
anyway, thanks for the comment.

I love the desert scene, the snowy scene is good too but it does not have the same feel.

Regards,

Will

great ripples on the dunes... are they done with a texture or another method?

Those are 2 very nice renders.

keep up the good work ^^

really nice atmos in both pieces :)

thanks, they are not done with a texture, but are actually a part of the terrain.

I agree with Will here - the images are both great but, for some reason, I seem to like the desert one more. I suppose it's because too many mountain renders have been done with Terragen, whereas that desert render looks like nothing I've ever seen before...

Hi Rich
Great images, I think the dunes are outstanding and by far the better image imo.
Could you explain a bit more about the displacement method you used to achieve the sand ripples please.
Simon.

yeah, please explain how you got the dune ripples (displacement?)
Title: Re: 2 renders...
Post by: Rich on February 04, 2007, 05:31:27 PM
ok i think i can explain it.
The basic part is a displacement shader, that goes into compute terrain.
On the function input of the displacement shader attach a Perlin 3D scalar. On the input of that attach a Multiply vector. Multiply vector has 2 inputs. On one is a "Get position", and on the other is a "Constant vector". My XYZ values for the Constant vector are 0.7,3,3. That's prettymuch it, then I added a terrain to the input of the Displacement shader. Oh and the Displacement shader displacement multiplier value is set to 0.15. I also added very small stones of a slightly different colour to give texture to the sand, and currently am rendering an updated version with more small scale ripples in the sand (added another displacement shader that has a build vector)

thanks :) will try that ;)

Thanks Rich, well explained.

how do you get desert hills? perfect like that?
Title: Re: 2 renders...
Post by: Rich on February 04, 2007, 08:21:43 PM
The desert hills are a fractal terrain. The fractal uses Perlin ridges as the noise type. Also try lowering the displacement roughness and spike limit so that the terrain is smoother.

ooohh, looks even better :) would you mind sharing your extra settings or supplying a tgd please?? :D :D
Title: Re: 2 renders...
Post by: Rich on February 04, 2007, 09:14:44 PM
Thanks. I have to credit photoshop for the simple color adjustment^^;
There's not really much extra in it from what I already said.
I'm actually not sure how to post a tgd, if i knew how then I would...

save it, then upload it to a post as an attachment ;) when you post, click additional options under the text box..

Post by: Rich on February 04, 2007, 09:40:19 PM
i hope it works.
Note: If you wanna play around with it, you should probably turn the cloud layers off, they are pretty detailed in my tgd.

Wow, awesome looking image Rich :)
Terrain is really beatiful, love those bumps and ripples. Cloud formations look very good as well!

I'm inmediately thinking of desert rock formations with rippled sand on the less steeper slopes (if you know what I mean :) )
You're image gives great inspiration  ;D
