Weather dds making

[mongoose]

So I am looking at making smog dds vs fog or haze dds files. All attempts to make something like this with Pain.net fail. Who knows how to make these, or haze.dds files correctly?

This is the Morning_Fog_Cloud_Horiz.dds which I had to make a screensaving picture of to upload.

Also when I tried to save the above as a dds file on my desktop I got this!

I want to remake this into a darker colour

You need to save it in DXT5 format to preserve the alpha layer.

So, I seem to have forgot how; in fact never knew; to produce a dds file as pics 1 & 3, using in this case Gimp. At the moment I only get the white background and not the alpha background.:dizzy: With fog, haze, or smog, where one has a very 'hazy' sort of spayed, 'paint' effect, I assume one can't do the traditional reversed black and white alpha dds as I do for more 'solid' airbase work that I have done before.

I don't have GIMP, but I did find this.

The alpha layer for DXT5 should be in smoothly blended shades of grey instead of the simple black or white of DXT1 with alpha.

I have no idea how to do a smoothly blended layer as seen in other's fog or haze dds files! I get definitive lines between and central 'smog' shape and the background alpha! :banghead:

Does GIMP has an airbrush tool?

[mongoose]

If you mean sort of like a spray gun tool, yes. My problem then is with such an ethereal painted layer. how to distinguish that from the alpha layer.
