Alpine Fractal (Updated again)

Hannes · January 10, 2009, 07:54:32 AM

Nothing special. I just wanted to create some alpine picture. I used some of Luc's cloudsettings.

Seth · January 10, 2009, 07:58:04 AM

the clouds look strange (scale problem ?)

Hannes · January 10, 2009, 08:00:48 AM

What do you mean, too big or too small?

Seth · January 10, 2009, 10:10:56 AM

i am not really sure, but here is where i think the clouds are strange.
they don't look right, transparancy looks weird in this part and the clouds seem very artificial , with less details...
whereas everywhere else they look like shampoo lather ^^

Yeah I see it. I think they're too big for the scene. As if they should be over a flatter terrain. Hard to explain really. Umm... ok, like you've created the clouds and then created the terrain to fit them, instead of the other way around.

thanks PG ! sometimes i really wish my english to be better so i can figure out how to explain things to people ^^

Nothing special, hah! That mountain range is well done. Clouds are about believable.

Clouds should have the edge sharpness decreased I think...

Hannes · January 11, 2009, 10:07:17 AM

Thank you all. I'll try decreasing edge sharpness.

I really like that mountain. Its one of the best I've seen so far in TG2.

Seth · January 11, 2009, 03:41:49 PM

indeed !
great mountain

I agree with Moodflow.
I do like the clouds' appearance ... I guess that you could swap the values for edge sharpness and density. And maybe divide the value of edge sharpness by 2 could solve this.

Tangled-Universe · January 12, 2009, 07:36:14 AM

Rather than most people I think you should keep the edge sharpness untouched.

If you reduce the density of the cloud and reduce the fake internal scattering and/or light propagation you'll end up with more transparent clouds with more gradients in color and density which will give a more natural look.
I agree with Michael (PG) about the scale, I'd reduce it by a factor 2 or so.

(The reason you have to reduce the fake internal scattering and/or light propagation (depends on the mix setting which of the 2 to adjust the most) is that when you lower the cloud density the effect of glow power will look stronger (sort of independently from the actual glow power setting).)

I hope this helps, but it will probably confuse you even more

Thanks again for your comments and suggestions!
First I'd like to show you an updated version which I started to render before I read the suggestions by Seth and Volker.
I tried decreasing the edge sharpness alone which did not help very much. Then I changed the noise flavour from Perlin billows to Perlin mix 2 and reduced the scale by 2 (I knew you would suggest this

)
The main thing was to decrease the smallest scale to 0.0001. Here's what I got so far. I like the clouds in the background. They are pretty detailed but in the foreground they still look a bit like bubble bath even if it's better than before.

I'll try your suggestions right now for the next version.

Seth · January 12, 2009, 04:46:06 PM

very good one !
