Very powerful creation program - not the easiest to use but once you're started you can produce good stuff.
Very powerful graphics editing program comparable to Photoshop. Works best under Linux, Windows version exists but is very flaky
Kind of a texture wrapping utility...
No description required. Probably the best graphics editor about.
The Clouds and Difference Clouds filters create nice Terrain heightmaps!
Commercial Product. (Evaluation copy available for download)
Getting better with each release. Almost comparable to PhotoShop. Unfortunately it's also becoming just as expensive.
WARNING – PaintShopPro alters a ton of windows file associations without asking. At least it did about 5 years ago, I haven't touched it since. It's taken me that long to fix my registry
ZxAnPhOrIaN: It didn't alter my windows file associations. .jpg (JPEG) files still open up in Internet Explorer!
Just translated into English (from Japanese). More "airbrush" style then "drawing" style.
A collection of previoulsy commercial products bundled into one package. The ~10M download includes Eleblend (terrain texture blending, artificial texture aging), Ripple Rain (animated water ripple bump maps, animated alpha channel rain maps), Mosaica (creates mosaic with matching bump map), Gradient Thief (multicolor gradients from existing images; good for skyboxes perhaps), and UT Screenshot Assistant (a batch resize/thumbnail image processor with image correction).
