md5anim (Doom 3 animation files) general facts
- Meshes (md5mesh) can share animations
As long as the meshes are rigged in a similar fashion, and they have the same exact number of joints and the same exact joint names, developers can use different md5anims for their meshes. The Dark Mod currently does not do this because we like size variances.
- Animations influence the size of the visible mesh
Suppose we take a single animation from a small character and use it for a larger character (as long as the previous conditions apply), then anytime the larger character uses that animation, the larger character will shrink to the smaller character's size. That would be a little strange if the character attacks you and suddenly shrinks . . . If we want that animation for the larger character then we would need to reexport that animation with the correct scaling option. See Scaling_And_Rotating_AI_Meshes and Advanced_character_rigging for exporting with a Maya to Doom3 work load.

- Same animations, different characters
The meshes can be different sizes but share the same animation as long as we export with certain options in the def file. See the tips on the bottom of this page: Advanced_Character_Rigging_-_Part_Three
- Reorganizations happen frequently if you are working on big projects like the Dark Mod.
Moving your Maya binary directory (the source files for meshes and animations) will affect the way Doom 3 handles the conversions. Once you move the directory and change the def file's -dest directory, D3 will think the source files are new so it will reexport everything. If your mod team uses CVS or SVN, only commit the files you changed if the md5anim joints match the md5mesh.
