gpapaioa Posted February 2, 2013 Share Posted February 2, 2013 Hello everyone. I am trying to import my Maya camera to Houdini. Both .FBX and Alembic almost work: camera is transfered but i get a jitter on the whole motion. Anybody experienced this? I found about mt_tools but I cant try them. The author is re-writing them (https://sites.google.com/site/freecgtools/downloads). Thank you Quote Link to comment Share on other sites More sharing options...
br1 Posted February 2, 2013 Share Posted February 2, 2013 I didn't have issues transferring from maya to Houdini using alembic. Can you describe the jitter ? Do you have an example file ? Quote Link to comment Share on other sites More sharing options...
gpapaioa Posted February 3, 2013 Author Share Posted February 3, 2013 (edited) In the following link you will find: the Maya scene with the camera and prop geometry, the Alembic cache export, the Houdini file and the plate of my scene in 640x360. Try to open both Maya and Houdini and see the difference. http://dl.dropbox.co...camera_check.7z Thank you very much Edited February 3, 2013 by gpapaioa Quote Link to comment Share on other sites More sharing options...
mawi Posted February 3, 2013 Share Posted February 3, 2013 There was no plate so I couldn't look at the track in H, and I couldn't get the geometry to show in maya. However keep in mind that when houdini imports cameras as alembic, you will manually have to set the resolution since it defaults to 640x480. If that isn't the problem I dont know, I never had any problems with alembic cameras from maya... Quote Link to comment Share on other sites More sharing options...
gpapaioa Posted February 3, 2013 Author Share Posted February 3, 2013 There is another .7z inside this file with the jpegs for the plate. Yes I know about the resolution, it doesnt seem to be the problem. Quote Link to comment Share on other sites More sharing options...
gpapaioa Posted February 3, 2013 Author Share Posted February 3, 2013 (edited) I think that I might found it. When I moved the timeline on Houdini on the last frame, the plate goes black. Which means that the plate is shifted one frame... i ll try to fix it Edited February 3, 2013 by gpapaioa Quote Link to comment Share on other sites More sharing options...
gpapaioa Posted February 4, 2013 Author Share Posted February 4, 2013 Well its not the frame shift either Quote Link to comment Share on other sites More sharing options...
bonsak Posted February 4, 2013 Share Posted February 4, 2013 Hi If you offset your image bkg sequence by one frame in H like this: "track_plate_`padzero(3, $F-1)`.jpg" it matches up. Cheers Bonsak Quote Link to comment Share on other sites More sharing options...
