I am attempting to create a quadruped skeleton for a dog. I tried taking a dog skeleton from Quidam and importing it to Motion Builder to create animation, but every attempt I either lose the skeleton or the skeleton gets all jumbled up. I am exporting in FBX format. Has anyone else had similar problems with importing FBX quadruped skeletons? I have also heard from my professor that there is a way to take existing motion capture data and convert it into a skeleton in Motion Builder 2012. Can anyone point me in the general direction of this feature, because I found some free Mocap online that I could utilize? Thanks for any help you can offer. 2012-02-07T08:19:36+01:00 http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/motionbuilder-facial-animation/page-last/ http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/motionbuilder-facial-animation/page-last/#When:20:45:46Z hi, I am a beginner on animation( I have no idea about 3d animation), I working on motionbuilder 2012 and I have a character that I am trying to control his face but when I select the face and alt drag it to the mapping list in the character face asset I get no shapes(mouth up,down,...)under the shapes tab !!! so is there any tutorial to teach me how to do this stuff !!! thanks 2012-01-25T20:45:46+01:00 http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/does-anyone-has-this-problem-when-use-kinect-to-do-mocap/page-last/ http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/does-anyone-has-this-problem-when-use-kinect-to-do-mocap/page-last/#When:14:08:55Z problem picture URL http://dl.dropbox.com/u/42630091/01.jpg Does anyone has this problem? the arm seem to rotate 90 degree....but i don't know the reason? when i apply this model to imported animation...its perform perfectly... so....i think bone mapping is correct?right? but if i use kinect to capture motion....this problem will occur.... here is my MotionBuilder file http://dl.dropbox.com/u/42630091/mia_blue_temp.fbx please...please help~ 2012-01-23T14:08:55+01:00 http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/best-facial-motion-capture-/page-last/ http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/best-facial-motion-capture-/page-last/#When:20:31:52Z Hello I am considering of buying OptiTrack sensors with Arena Expression software and whole bundle is 8000 $ which is not really too much for a good mocap system BUT my question is:Is it really good for facial expessions and why should I buy it if I can buy ZingTrack 2 which is way way cheaper.Please could somewhone tell me the difference in those two except the huge difference in dollars :-D Also what is the difference between MotionBuilder and Softimage Face Robot for doing facial mocaps.Which one is better?

I have a question about export c3d data to bvh data in motionbuilder. Does anyone know any tutorial about this ? or maybe someone could explain me how to do this in small steps. 2011-11-21T06:17:43+01:00 http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/basics-of-actors-and-characters-in-the-mocap-pipeline/page-last/ http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/basics-of-actors-and-characters-in-the-mocap-pipeline/page-last/#When:23:41:50Z Hello, I try to understand how the information from a motion capture system is transferred to a rigged character in Motionbuilder. I suggest the following pipeline: First I have my optical markerset which consists of translational information of each marker. This translational information is mapped onto my actor. Plottin this actors movement to a character gets me a control rig which has both translational and rotational data. My question now is how and when the rotational data of the control rig is created. Does that happen during the baking or even earlier? I’m just trying to understand what’s the difference between the actor and the characters. Thanks for your help. Best regards, Bjoern P.S.: Sorry for the doubleposting, I didn't managed it to move my initial post from Motionbuilder12 into the Mocap-forum. 2011-11-20T23:41:50+01:00 http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/motion-data-problem/page-last/ http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/motion-data-problem/page-last/#When:09:54:33Z I am new to motion builder, and having a problem. The lab I work for uses motion capture of eight data points, four on the head and four on the sternum. It gets exported in .c3d data. I downloaded some dummy .c3d data online so I know how to use it to drive an actor and such. However, the data we get from our lab will not run an actor. I use the data points to create a marker set, yet when the data points move the marker points do not move also. Is there something I am doing wrong? Is a full body set of markers required or will head and chest data work alone? Is there a problem with the data? What can I try differently? 2011-11-17T09:54:33+01:00 http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/how-to-clean--eliminate-noisy-data-on-bvh-files/page-last/ http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/how-to-clean--eliminate-noisy-data-on-bvh-files/page-last/#When:19:11:24Z Hi Guys, I'm new with motionbuilder. Is there a way to stop or eliminate noisy movements on BVH files after importing it to MB? Any tutorial of the method or process would be very helpful. Thanks 2011-11-16T19:11:24+01:00 http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/cross-machine-live-motion-capture/page-last/ http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/cross-machine-live-motion-capture/page-last/#When:10:37:00Z We have a 64-bit computer capturing gross-body movement in MotionBuilder, and a 32-bit computer capturing facial movement in MotionBuilder. Currently the system means that we have to transfer the motion capture data from the 32-bit computer to the 64-bit computer and take the time to combine and sync the performances. We would like to streamline our process and connect the computers together, to allow the facial capture to stream live from the 32-bit computer into the 64-bit machine's MotionBuilder, parallel to the gross-body movement that the 64-bit computer is capturing. Does MotionBuilder support this type of cross-machine capture? If so, how? And if not, are there any other plugins/connections/applications that allow us to do this? 2011-11-08T10:37:00+01:00 http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/losing-animation-keys-when-ploting-on-skeleton/page-last/ http://area.autodesk.com/forum/autodesk-motionbuilder/mocap/losing-animation-keys-when-ploting-on-skeleton/page-last/#When:23:12:22Z Hello everyone, Let me set up the scene for you first, I only got motion capture movements for the body. I'm working in the story window so I've got the motion capture data in a Character Animation Track and I am adding by keys movements for the hands with the Expression Constraints for each hand in a Character Additive Subtrack. My problem is that the constraints are working on the control rig but when I want to plot the animation to the control rig and finally plot it on the skeleton to export , I'm losing the animation on the hands. What am I doing wrong in the process? 2011-10-31T23:12:22+01:00
