Thanks mate, these are really nice!
Until you started these mods, I assumed that we can only use greyscale images for cloud layers.
The skies, what a long story !...
A long time ago, I have tried to do colored skies with personal pictures.
The results were absolutely disastrous.
With a lot of experimentations I finally found how to do for exactly connect the sides
of the textures two by two: up and down, right and left, and the corners...
(However it is not as easy as it seems and it takes a lot of time, work and tests ...)
But what I did not yet know is that it was possible to use textures
larger than the original one which is 1 MB.
This explains why at first I made these textures in indexed color to meet the size of 1MB.
(just like planes skins or big grey level cloud textures.)
The results were decent but not great.
So I explored other formats, and surprise: It worked !!!
It is therefore possible to use the RGB mode and more, with an alpha channel !!!
So we can determine areas with more or less subtle transparencies from the background IL-2 sky ,
which, admittedly, offers an attractive degraded of blue and cyan realistic enough ...
Thank you very much VP, guys like you and over modders give a lot
to the "visual playground" of IL-2 !
