Martian Sunset

[Franky]

I'm not entirely pleased with how the land turned out, however the sky is exactly the way I meant it to be.

Martian skies vary from butterscotch to rosy pink. However, when the sun nears the horizon, it creates a kind of bluish halo around it.



I'll try to change the landscape and render again.

The overall atmosphere does look like some mars photos i have seen. Good job. Looking forward to the changed terrain.

i never knew mars had this kind of atmo colour its a really cool atmo!
yeah i have to agree about the terrain it could be better

Great SKY nicely done

The atmosphere's realy cool, but there is way to much variation in the surface fractals. Try using several fractals with similar colors and use a shader with a low variation to blend it all.

Here are some reference photo's rom the mars landscape:

I agree with you about the sky.  Your terrain needs some realism...for Mars, anyway.  Good render.

yes the terrain of mars is more dark red like

I took another shot of the sunset. This time the sun is seen starting to fade in the dust as it approaches the horizon. Due to the low lighting at sunset, I've rendered another shot, this time from the afternoon in order to better illustrate the terrain.

That blue effect is really cool.  Do you do that through the atmosphere or through the sun's lighting itself?

Looks like a change of the Base Sun Color under the Lighting Conditions Dialog to me, just to venture an opinion.

Regards to you.

Actually I had to really play around in order to get the right effect. True Martian sunsets (from pics I've seen) are actually a little more grey but I thought I'd enhance the color just a wee bit. What I did was switch the blue sky and light decay colors, increase the atmospheric density, and then the further you bring the sun down towards the horizon, the more blue its halo gets. Basically, Earth and Mars have skies opposite from each other.

Martin sunsets have blue color in the sky and not around the sun....

And I suppose you've seen them first hand. If you're judging by NASA's one photo then you can not say for sure that the blue glow only appears above the sun. Look at all the variations in Earth's skies. Although the dust most likely does cause the glow to appear above the sun, that's not the way TG2 rendered it, though I've tried to get it a bit more accurate. Well, tried except I increased the colors a bit because they look kind of dull in NASA's pic.

@Franky - What one person sees may not be what another sees.  We've even seen differences of opinion about Earth scenes.  What we all need to decide then is whether we're creating the scene for our self or for others.
