This is a Python program that I made recently. It currently reads BCK files, which are the joint animations used by BMD and BDL models. Support for editing will come soon, but right now, this program can export a text file that contains all the joint information in the animation.

https://www.dropbox.com/s/195tf4bbcp7s40a/PyBCK.zip

Usage:

python bck.py [flag] ...

Flags:
-e: Exports the BCK to a text file, with the BCK filename and optionally, the name of the text file, as an argument

Is there any usage to this? I mean, nice job but can't bmdviewer2 detect joint info?

Like I said above, PyBCK will soon have support for editing animations. Also, bmdview2 only gives you joint information for the model, not the animations.

It'll soon be able to edit animations? That's going to be awesome :O

How will that work? It's a Python program so it'll be REALLY hard to use.

Only if you don't know how to use the command line, which is incredibly easy to use.

That's blarg. Command line feels totally unnatural unless you're a Linux-nerd.

Anyway, that's a nice tool. I hope it can help us understand how animation data works.

But really, it isn't that simple.

Running a command line? Isn't too hard. Unless you know all the values and which goes where and what does what.

Well still, lacking visual is lacking charm. But I credit you for your work.

You can also export bck and bca with mkds course modifier. It exportes to ma (maya ascii). You can find in tools menu.

We aren't going to be using that. Sorry.

Well, it's still useful to use

That is, if it's functional enough...

My code almost supports editing, but I'm getting an error. Here is the code: https://www.sugarsync.com/pf/D9745722_62761472_619841

This is the error I got.

Now I've managed to fix the error, but it produces incorrect BCK files.

blank, if you're ever on these forums, can you please take a look?

The only thing I noticed after a brief look that might cause problems is that you only export/import one scale, translation and rotation per joint. I don't have any BCK files at my disposal at the moment, so I can't really test it.

Marionumber1

Yeah, I ignore the count variable, since that would make creating this editor even more complicated. I'll take a look at the original BCK and see if any of its count variables are greater than 1.

Kind of like I expected, many joints have more than one scale, rotation, or translation value. I'm not quite sure why joints would have more than one, but I guess I'll have to implement that.
