Background wont save on TGA and PNG?

[AcesHigh]

Am I missing something?

When I render the image, I have this beautiful sky background. When I try to save it as TGA or PNG, the background is WHITE. If I save as JPG, I can see the sky background.

PNGs have integrated alphas, so the information is still there, but you need a specific means to remove that alpha information. I believe XNview (its freeware) has the ability to do this.

Targas should actually look the same as they do in the viewport. They support alpha channels, but they have this saved as a explicit channel within the image (ie PNGs are like RGBA...TGAs are like RGB + A)

Or you can just remove the alpha VFB Channel and then pngs will render WYSIWYG.

gosh, but even photoshop cant see the alpha channel?

when opening the PNG in photoshop, instead of the background I see that checker pattern, indicating transparency. There are no additional layers and on channels tab, only RBG, no alpha.

That's due to PNGs RGBA nature. Use TGA format instead. Then you'll get the background plus an additional alpha channel.
