Poser figure with bones that match Carnegie Mellon MoCap Report this article as Inappropriate to us !!!Login to Reply

I want to use Using Carnegie Mellon MoCap files as an animation guide in DAZ/Poser to animate V4 + M4.
These are the files I would like to use:
http://mocap.cs.cmu.edu/search.php?subjectnumber=%&motion=%

I know there is a conversion here, which is very very cool but ...

http://www.sharecg.com/pf/full_uploads.php?pf_user_name=mojodallas

They actually don't load onto V4+M4 very well for my purposes, since I can not tell how the original body movement was meant to look. The conversion, as cool as it is, screwed with the moCap a bit too much.


Here is someone elses attempt, you can see what I mean:

I want to try a different method. What I need is a Poser figure that has the SAME skeleton as the Carnegie Mellon files so it will work without doing any conversion.

I, to apply the motion to my Poser V4+M4 figures, I will use this 2nd figure as a 3D guide in DAZ. I will manually hand animate my V4 figure to match it. This will give me a result that is closer to the original body movement than what I am getting with the converted mojodallas moCap files.

All I need now is the right Poser figure with the right skeleton to match the Carnegie Mellon files. I am not sure where to look for such a thing. 


Then I can get started converting this excelent MoCap resource to beautiful, jitter free, Poser animation format.

Any help pointing me in the right direction to find this Poser figure would be awesome.

What you're going to have to do is rename those bones in the bvh files.  It "might" be a V1/V2 compatible file, I'm not sure.  (The author said he tried to make it compatible with some Poser figure (Victoria) but I don't know which version offhand.)


What you need is a program to edit the bvh.  I used "BVH Hacker" originally developed for Second Life but easily useable with these great CM bvh files.

There are several sites describing how to use bvh hacker.  Google 'em up and open the bvh files.  It helps GREATLY to also reduce the frames in these files.  BVH Hacker has a utility in it for that as well.


Rename the bones in the files you are tweaking according to whatever figure you are using.  You might have to put in further tweaks as well.


Good luck!


PS - I played around with these and used bvh hacker for fixes.  I had no problems making them useable for V4's skeleton. (Same as M4/A4/Girl4/etc..)  I also used bvh play: http://sites.google.com/a/cgspeed.com/cgspeed/bvhplay  to view the files but, it chokes on some of them, IIRC.
