slade Posted August 5, 2004 Share Posted August 5, 2004 hello all, I would like to know if its possible to import motion capture data into houdini, in a raw unedited format such as the emf format from the reactor core mocap system.if so how can I import the data, tru the use of scripts ? I have no clue how this is done in houdini. I currently use Motion builder and 3dsmax6 " don't flame me you guys" to edit my mocap data. I just want to make use of all of houdini's power. Thanks in advance Bjorn Quote Link to comment Share on other sites More sharing options...
stevenong Posted August 5, 2004 Share Posted August 5, 2004 Hey Bjorn, Houdini only reads Biovision, Acclaim and Motion Analysis motion capture files. So if you can output in any of the mentioned formats, you might have a chance to import in the data. With 7.0.142, you can search the online help & please search for "motion capture". You will get information on how to convert motion capture data into channel files & scripts to be read into Houdini. Good luck & please let us know how it goes. Cheers! steven Quote Link to comment Share on other sites More sharing options...
old school Posted August 6, 2004 Share Posted August 6, 2004 The three houdini commands you need to know to convert the three aformentioned formats are in $HB called: mcacclaim mcbiovision mcmotanal Just run the command in a shell to get the useage. In general, you supply the motion file format and out comes a .cmd file of houdini scripts and a .bclip for the channels. In Houdini just source in the .cmd and everything should come in fine. The .cmd file contains the bone networks for the motion files. There may be some legacy houdini demo files around. If not, email me directly for a couple example directories.

slade Posted August 6, 2004 Author Share Posted August 6, 2004 Thanks alot you guys, I really appreciate the the response. Old school, in your professional expericence with mocap in houdini which format handles the best , or do they all handle the same ? I am going to start with converting the emf files to the biovision format. Also can I use multiply switches, for instance can I use the -e and -o together ? This is going to be very tedious but it will be worth it because it will get me 1 step closer to understanding the awesome power of houdini. I will let you guys know how it is coming along. Thanks again old school and steven. Bjorn Quote Link to comment Share on other sites More sharing options...

Mcronin Posted August 25, 2004 Share Posted August 25, 2004 I'm not sure how much things have changed over the years but I distincly remeber at one point Acclaim didn't support bone length/scale values, but biovision did... Or was it the other way around? You should search google for info about these file types to find out exactly what they do and don't support.

lexlopez26 Posted November 7, 2016 Share Posted November 7, 2016 Hello guys! I've been struggling for a while to figure out how to bring capture data with a mesh in houdini. I have the capture data as an fbx file. It was exported from motion builder as an fbx with the mesh but when I import it in Houdini it shows me the mesh without the animation. Any ideas on how to fix this? thxs -Alex Quote Link to comment Share on other sites More sharing options...
michael Posted November 7, 2016 Share Posted November 7, 2016 without seeing the file it's hard to say - is there a deform node? Quote Link to comment Share on other sites More sharing options...
Atom Posted November 7, 2016 Share Posted November 7, 2016 (edited) Only baked data comes through the FBX file format. So if you can create a keyframe on every bone inside of motion builder then export it as a FBX it might work. Look for a baking feature inside of motion builder (they may use another term, however) I have tested this kind of transfer from Blender to Houdini and it does work.
