Subject: Couple realistic sky questions

In C5Pro the sky becomes darker and darker with each cloud layer I enable. How do you add cloud layers without making the sky itself darker? I'd like to be able to add clouds without affecting actual sky color at all. Is there a tut out there anywhere on adjusting things in realistic skys? Sometimes I'll adjust a color parameter, for example, and the results aren't what I'd expect. I'm sure it's just because I haven't figured out the feature yet. Thanks. Edit: Forgot to mention that when I adjust Global Brightness in an attempt to correct the 'dark sky' thing then the clouds become too bright.

...oops. Forgot one other thing. When I change settings in realistic skys they frequently don't 'stick'. Yes, I'm clicking "Ok". Sometimes half my changes stick, or none, or all. I haven't noticed any pattern. Am I overlooking something, or is this a bug?

Maybe render the sky with the cloud layers and then brighten the image using an image editor and then use that new image as a background image in another render?

Tunesy maybe we should make a bug report about the settings not sticking. That happens to me all the time.

Edit to add. Mine is C5Pro with the SR5.05. :D

My brain is just a toy box filled with weird things

" Maybe render the sky with the cloud layers and then brighten the image using an image editor and then use that new image as a background image in another render?" Yes, I could do that but I'm hoping it wouldn't be necessary. I don't have a project or anything where I 'have' to do this. I'm just trying to learn more of the details of Carrara that I haven't had a chance to spend time on up to this point. Frankly, it's no big deal to me if it can't be done within Carrara. The real sky settings not sticking is driving me nuts though ;)

At first I thought maybe you were exaggerating a little about the darkening. I haven't really used the cloud planes much since the volumetrics came out. I went back and checked in Carrara 4 and now in 5, and I think you've hit on a bug. I think the alphas of the cloud planes aren't working correctly in C5. It doesn't cause that much trouble with one plane, but after that the sky gets quite dark. I'll report this to Eovia. As far as settings not sticking, I haven't experienced that. Are you Mac or PC? With the sky color, it is difficult to get any really useful tweaks to the color. It is so tied to the haze and atmospherics that even a slight change causes havoc to the scene colors. Great if you want random alien skies, but really useless for trying to pinpoint a specific real world sky color. Perhaps I will also have a discussion with them about that, if they are receptive.

"As far as settings not sticking, I haven't experienced that. Are you Mac or PC?" I'm on a pc running C5P 5.05. The problem with the settings not sticking is sporadic. Sometimes it works fine for a few sets of changes, then they won't stick several times in a row. 'Seems' to be pretty random.

I can confirm the sporadic settings not sticking.....Sometimes the color choice sticks, sometimes not. It would be nice to have a gradient option the sky editor as well....hard to get dark places....like a storm system moving in etc etc...wnat to be able to get multiple colors in the sky.

I have the same problem with settings not sticking. I'm also on a PC.
