Hi,
I have to make many skies for a production in visual industry. So it's very important for me to have some answers about what can Terragen do in my case.
It's very simple. I have to render skies (night, dusk, dawn, etc) with clouds. The length of the sequence is nearly 20min (!).
So, i decided to render skies without clouds and render clouds alone to put it in a compositing software to animate them in 2D.
My question is: how to make clouds layers without sky?
OK u will say to me: look at Temporary files for the alpha channel etc... BUT it doesn't work at all for clouds. The alpha channel of the clouds take the color of sky and the alpha channel is not white and blanc but white and blue(??).
I try with another method. Render clouds withouth primary visibility of sky or secondary. It's better but not exactly the same render with all clouds and sky.
So, is that possible to make "easily" sky and clouds separated in Terragen and HOW?
I try to put Terragen in the pipeline in my special effects studio so it's a little bit important ;)
Thanks a lot.
why won't you just disconnect the atmosphere node? wouldn't that give you what you want?
MMh, if i do that the color of the atmosphere won't diffuse on clouds? I will have like a black light on these clouds.

not if you use a fill light setup instead of GI.
OK, i'll test it. Thx.
let us know if that worked for you!
Yes, i will. ;)
On the atmosphere node there are two checkboxes called "enable primary" and "enable secondary". If you disable the first, the sky will not be visible but it will still affect the lighting on the clouds.
Okay, THAT is simple...
Why didn't see it before? ???
;D
Many thanks and see u soon on this forum...
