Firstly I did one long shot of video during 15 secondes. After , I tracked the column (see the black cross) with MatchMover .After I constrained 2 pictures 3D in Maya. All that is perfect. But I have to simulate in Combustion 3.0 a flying buterfly around the column. (see the the red way. It begins far away of the room.) My problem is the traking of the particule because my caméra is shaking with the long traveling. How constrainthe particule with the camera?
Thanks a lot

hmm ...I not sure i got quite right but here goes...
It sounds like your problem is the fact that your camera is shaking ...now since u have been able to constrain the pictures on the wall to the footage i assume that you were able to make the 3d camera in matchmover to shake like the video camera. If you have been able to match your 3d camera with your real camera then all you need to do is download a maya-script called mtoc from highend3d.com and you can use that script to export the camera data from maya to combustion then import the workspace that the file the script makes into your current project (remember to put .cws behind the name of the file when u use the mtoc script) copy all the camera keyframes from your mtoc scene to your work scene camera, then make sure that video layer's depth order is set to background in the layer settings then the combustion camera wont have any effect on it. That should do it! If your problem is like i think it is, their are other ways of doing it of course but this way is by far the easiest and gives the best results. Let me know if this helps.
Ps. I am looking forward the 3DS plugins to import model in Maya. I canÂ’t find it.
here u go

Hello JR. It works perfect. !I downloaded the mtoc script and I imported in Combustion. Firstly I had a problem of focal camera. After I kept the mtoc camera and imported my tracked video and the particules. It is ok. Thanks a lot for your help.:)
I think I will have some more problems in my project. May be I ask you one again. (For example, I have to make a mask to see the particles turn around the column. I donÂ’t know how put my layer mask to mach it. my 3DS plug-in in MAYA 5.0 doesnÂ’t works)
Thanks a lot
