Sky becomes grey

[Badu]

Even when i changed in 3D my background in a clear blue sky, when i make a photo, the sky becomes grey.
I tried different scales of blue.

As explained in the help:

If you selected a color for the sky in the 3D view pane or if the current mode is Aerial view, a sky image computed according to the hour of the day is used for the rendering of the sky. If you chose a texture for the sky, that texture will always be used in Virtual visit mode whatever the selected hour.

I guess what you see isn't completely gray but is the bottom part of the sky image. If you want a plain color in the photo you create, you should use a texture image containing only that color for the sky (it doesn't have to be big, a image with a few pixels will be enough) .

Hi Emmanuel,

But even when i choose color (i.s.o. texture) the sky is blue in the normal screen, but becomes grey when I make a photo.
