Sometimes, trying to make clouds with GIMP gets a little impossible for someone that dont knows how, this FAQ will show you a very easy way to make it in GIMP:
First, you need Gimp, a link for it can be found at the sticky.
Second, you must know what you want.
For this FAQ i will use a sky found in the ZE files.
Next, get the sky and open it with GIMP.
This one for example:
Search for this tool:
Low opacity to 50
When you have done that:
Select a size, color and shape for the tool.
Next, start painting.
Remember: light colors for the edge, and darker colors for the inside.
When you do it it may lookm like this:
Then add darker colors:
Then, search for this tool:
Then use it until you get this:
Ok, ok... i didnt worked it too much, its only to show you.
You can give it more details with the pen tool, or if you dont like work, XD, you can use some tools that can be downloaded and they come shaped, but they dont ussually get the shape that you want.
Remember to save as TGA and dont save it with RLE compression or BF2 wont read it.
Any question ? Did i missed something ?
thanks for the help, that will certainly make custom skies a little more "custom"
