Outdoor Environments Tutorial

[RawkBandMan]

Mk, so, can anyone who has used GIMP for a skybox help me out? I have downloaded a texture from cgtextures, and I have gotten the dds plugin for GIMP, but no matter what I try to do with it, the editor will not find the file.

I tried to get a trial of photoshop, but they don't seem to be offering them at the moment.

Any information would be most appreciated, and if I need to provide more info from my end, please let me know.

Thanks.

I would also like to know this. I can open it, Make it 8192x1024, then I Save As, .dds, I choose DXT1 and generate minimaps, but then it says "DDS: Cannot compress images whose dimensions are not multiples of 4.
Saved image will not be compressed."

It also says "DDS: It appears your image may be a volume map,
but not all layers are the same size, thus a volume
map cannot be written."
