  • XSI import/multiple scale issues

    I’m having a multiple scale issue upon importing 3D scene data from XSI into AE. It seems that everything is off by a factor of 1:100 (the world units in XSI were set to feet). When I do nothing to the camera and lights, anything that becomes a child of either light in the scene, needs to then be scaled to %1 to be normal size. Obviously this become a problem when postion keyframes are then applied, and even more of a problem if this object becomes and emitter for trapcode particular.

    I actually have a link to the file, which is posted on my .mac file sharing page. There is also a stuffed version of the file (just in case) and a reference quicktime that is a render of the tail end of the scene for (the 2nd scene light is centered on the model’s waist).

    The AE file has the original imported scene comp with the multiple scale issues in it. There is also a second comp were I tried applying expressions to the position of the camera and lights. I just can’t get it to work right.

    If someone could take a look at it and let me know what I’m doing wrong, of if they have any suggestions, that would be awesome.

    Thanks.

    Never mind. Someone helped me with it:

    Basically apply this multiplication expression to the postion of the camera and all lights (from mylenium:

    [position[0]*100,position[1]*100,position[2]*100]

    Then apply this expression to the Point Of Interest of the camera (from ats):

    [pointOfInterest[0]*100,pointOfInterest[1]*100,pointOfInterest[2]*100]

    works like a charm.

    This translates feet world units in XSI to pixels in after effects. Meters the factor would be 1000.

    Hello,
    apart from the scaling issue…

    How do i get my XSI camera data imported into after effects?!
    I know it supports maya camera import, but i just can’t get my XSI camera into AE.
    I’ve tried RLA.. but that didn’t work (or maybe i missed out on something!?)

    Cheers

    Barry
