I created an alpha plane, enlarged it, and placed it in the background of my scene.
The transparent part of the image is acting as some kind of filter on the sky. How do I fix that?

The atmosphere I used is "puff" (which is under Sunshine and NOT a volumetric atmosphere).

sample images:
Default Puff atmosphere:

With Fog and Haze set to 0%:

I'm giving it a try.

It worked easily for me. Maybe its an update you are missing?

Here is an attempt. I took the psd and converted it to a bmp, created an alpha in PSP, added to a scene, with fog and haze, and added some cloud spheres in the front to add more atmospheric perspective

And here it is at night

everything's up to date. hmm..
i'll try bmp.
did the photoshop .PSD cause any problems?
i'll post my vue file.

thanks to everybody for trying this.
I think I figured out what was wrong (it's still a bug).

Here's a working scene:

and here's my setup:

Now here's where it falls apart. If you make your alpha plane TOO BIG and push it way into the background (like I originally did), then you'll get the strange alpha channel problems:

(look at the top of the deathstar planet)

thanks everybody.

oh and thanks for the foreground clouds recommendation redtrek
