I didn't make it!
For those of you wanting to mod JK3 on the go, I was told about this beta open source utility called uMod. It works for any game using DirectX version 9. It is textures only mod no mesh yet.
Here is the link to the homepage: texmod - Universal Modding Engine - uMod games on the fly! - Google Project Hosting
There is a tutorial video on the front page and looks pretty simple as long as you have a DDS editor in your tool box. If you don't, get the Gimp, or you can use this;
The first time I ran this I dumped all the textures. The video shows you the best way to do single selected textures.
JA uses OpenGL for the renderer back-end, not Direct3D. I don't think this will work at all.
What do you mean you "dumped all the textures"? You saved all the textures JA uses to a file? Why not just extract them in their raw form from the PK3s?
Also, JKA doesn't use DDS/DXT files... those are Direct3D-specific file formats.
What is this thing even supposed to do? JKA is based on the Quake III engine which is renowned for its mod-ability so any content can be replaced with anything. And developers have the JKA SDK to completely change the game's functionality...
If you want to swap textures "on-the-go" you'd need to use an OpenGL texture debugger. Why would this be beneficial? Many mods support shader remapping as well.

TexMod is unnecessary for JK3. TexMod is better used for games that otherwise don't really support texture modding, like the Mass Effect series as an example. Because JK3 is so accessible to modders already it's not practical to use TexMod, which you need to actually be running in the background to have the mods work. It's like making modding even more difficult.
