Hi
I'm trying to find a tut that addresses the problem of unnatural greenish skys that carrara tends to render if left on default settings.

I've seen the free tut somewhere before. I don't recall if the tut was a video or just stills.

There was just a couple simple lighting adjustments that gets rid of greenish yuck.

Anyone seen that tut? got a link?
Thanks
Frank

If you ever find it let me know.  I simply can't get Carrara to adjust it's sky color.  Every time you move the realistic sky sliders to change the sky and haze light base.  The stupid program slides em right back to where they were and doesn't let them be changed.  Either that or it changes them back to the green default just after you get the whole scene perfect and ready to render...

Whoever designed the real skies module for Carrara ought to be hung out on a flagpole somewhere near the top of the Empire State Building and be left for the falcons to have as a snack.

I've never had a problem with greenish skies. I have to brighten them up, but haven't seen them green, and I've spent a lot of time in the RS room.  Perhaps your monitor is a bit off, I don't know. Look at my gallery and see if the skies look green.

 But, the color wheel for the sky is fixed in 7.0. The colors stay, but if you start changing haze also, everything interacts so you have to be careful.

The sky in Your picture "Bright lake" leans toward the problem I'm having. but mine is more green

Yours sky is not really green, it's just the blue does not seem right and seems to have another color throwing off the blue I would guess it's green mixed in but not not showing as green, just enough to mess with the blue.
If that makes any sense.

I found the tut and posted a link to it.

Thanks

Just curious.
Do you see the problem in the Carrara render room image?
Or, only when you take that image into, say, Photoshop?
Have you bought a new screen lately?

Brian

It's when I render to screen while in carrara. Just render room

A good example of what I mean is in carrara 7 pro assembly room browser under MISC. there is a file called spectral clouds.

It's an animation, just set time to 0 so it only makes one frame

Just render one frame of that and check the sky.

to make the one frame render faster  cut the size down to 1000 x 500

You will see the messed up blue green I speak of in the sky.

monitor is good less than a year old and color is good.

Thanks

Using yellow sunlight and a blue sky will result in greenish colors.
(I am reading the great tutorial ddaydreams linked to)

That's funny. I made that spectral clouds scene and it was never an animation. I guess it got saved that way by mistake.

As far as the green, the color wheel in C7 works.  So, you should be able to get the sky to stay whatever color you like.

Also, that is a very informative tute for the RSE.

I'll also be posting  a new landscape, maybe later today, that will appear in ImagineFX magazine  with their Carrara 7Pro review.

Sounds great!  I can hardly wait to see it.  You know, I just had an idea I may post on the Daz forums.  A lot of people use Carrara for space scenes, yet, as it is now, you need to go into a 2D program to do starfields and nebulas etc.  Why couldn't the basic realistic sky system be adapted to also do space backgrounds?  I think the only major bit of reprogramming that would need to be done would be to put in a generator for stars and suns.  The existing cloud system can be used to simulate a nebula. And get rid of the stupid horizon if your not enabling the ground...  That annoys the living heck out of me.  To get the horizon down below the render scene, ya have to set it at like -7000' or more.....  I think when you disable the ground, the horizon should be gone, period.

Thanks for posting that pix.
I tried the sky color setting that you point at and could not get the color blue to show up in it at all.

Then I changed the sun to white and then I could get all the blues I needed to show up in the sky color settings. and could generate nice blue skies
So a nice blue sky but have to have a white sun to get it.
Hmmm

I'll be looking at the tut more.

Yeh, I could see if there was a bit of sun saturation near the actual sun position, but the way it changes the entire color scheme is very unnatural.  Our real sun isn't really white, it shades faintly towards yellow.  It would be nice if we could get that proper lighting effect.

Yes Sparrownightmare.
In the real world we have a yellowish sun in a blue sky and it does not turn our sky green. At least not normally. I'm going to have fun looking into this further doing some other things the tut mentions like change the background color from none to blue. Or swapping out the sun for a light and making the light yellow.

As I see it, all you need to do is to change the Default sky colour of that file from it's green to blue !

Simple?

Brian

Hi

Should be simple.
Tried that,  but blue was really hard to dial in and still renders green unless you change the sun color to white.

Without  doing anything to the sun leaving it orange like in your pix. Change your sky color to light blue (very difficult) the little rectantgle has a hard time showing the blue that gets picked on the color wheel, but when you finally do get some type of blue dialed in, hit render, and the rendered pix comes out green still.

Brian

Yep changing the sun makes all the difference. yours looks good like what I get when I change the sun
Without changing the sun( leaving it orange), the sky would still turn out green even with the sky color set to blue.

Odd

My adjustments, only to the sky colour, seemed as I would have logically reasoned.

All good fun anyway.

Brian

If you notice, in this scene there is a helper spot to light up the underside of the clouds. I haven't played with it, but it might have some effect also.
