Free tools

My dev suite, such as it is.

Blender - 3d dev
Gimp - image editing
Notepad++ - text editing (has an ArmA plugin that has some neat features, including one that will build the private definition), and syntax hilighting for programming languages
WinMerge - text (and binary, IIRC) comparison utility, for figuring out what is different about 2 files
Universal Extractor - will unzip almost anything, including most NSIS installers, and even some other kinds of installers

There may be better stuff out there, but these are the ones I've found to be very useful and powerful.

(Oh, and each of those are "portable" in that they have versions that you can put on a USB thumb drive and use without installing to a host PC.)

Thanks for posting the list. Will have to check if our PMC Editing Wiki: Editing Tools page is up to date with them.

Would you like to post some generic things (or even detailed if you have time/energy) about Blender? If you can, just open a new topic for it.

Or you can post things about notepad++ or other utils too

hehe

Yeah, let me work up a kind of overview for each one, then I'll post it.

I rather like Wings 3d: http://www.wings3d.com/ Simple; a bit like Sketchup.

Then there's Art of Illusion: http://www.artofillusion.org/ Definitely not too simple, but very powerful.

K-3d is nice, too. http://www.k-3d.org/wiki/Main_Page
