Modifying existing animations?

In my initial post, I mentioned that the animation files wouldn't open anywhere. The animation format is .ma, and the program that packages these animations is called Alias Maya. However, for some reason, the animation doesn't open in it. Perhaps I need a newer version.

1. Finding the animations is straightforward. First, we need to locate the animation configuration files. This can be done in two ways: through the map editor or manually. You need to go to the _(AnimSet) folder in data.pak and search there. Obviously, all creatures will be in the Creatures folder. It's easy to understand everything if you have basic English knowledge. Accordingly, heroes are located in the Heroes folder.

2. These configuration files contain the paths to the configuration files of the individual animations. Individual animations are located in _(BasicSkelAnim) in the same data.pak. For example, all animation configurations for Nightmares are located in the _(BasicSkelAnim)\Creatures\Inferno\NightmareBurn folder.

3. We open the animation configuration file for the idle animation, i.e., idle00. Personally, I use Notepad++ to edit configuration files and other things – it's a very convenient tool, and it's also free. So, we open the animation configuration file and see a line like this:
< uid >4C97293E-55FF-4E77-990E-26A9AA481E94< /uid >

I had to add spaces between < and uid, otherwise they don't appear in the message.

This ID between uid and /uid is what we need, as it is the animation file. We find it by searching in data.pak and copy it somewhere. Then, we add the format, in this case, .ma. That's basically how we export the animation, and then I have no idea what to do next.

Actually, I'm not entirely sure if this is what's needed. But so far, I haven't been able to find anything else.
