hey malcolm !
thanks for your answer ! So I added a target tag to my cam, looking at my cube, and it worked ...
only thing is, my goal isn't to make it look at a specific object but just do exactly the moves I have in C4D. In TD in the look at param of the camera if I put $FBX_IMPORTROOT/ I get the right camera translate view but not the roatation, it's logicaly looking at the center of the scene ...
So I made a quick new scene for some tests, export it as FBX and I get some intresting results.
when imported, you get the right camera movement, just not in the right place somehow.
when you put in lookat "$FBX_IMPORTROOT/" it look to the center of the scene, it's better looking, but still not the camera move it's told to do.
So last idea I had was add a null object children of the camera, a bit in front of it, and set it to be the look at ( $FBX_IMPORTROOT/Camera/LOOKATME ), I feel it's working better, but still it's not the right camera move... and that I don't understand ...
and also why does the camera have to look at something ? because it should be okay without looking at anything right ?
