I'm creating an animation of a film bed with a film strip running through it. The film strip is basically just an array object with a curve modifier. What I want to do is use an image sequence for the material that is being tiled along the array object, and offset 1 frame for each duplicated array object. Thus giving the effect of moving images on the actual film strip. I hope this makes sense, and I'm just assuming that this is a python requirement, as I can't think of anything to do it with in the Blender toolkit.
Instead of using the the Array modifier
To expand on Dan the Man's comment, one way to do this would be to use an external tool to append the image sequence into one wide image.
One tool that might be good for this is Image Magick.
to append an image sequence on Linux, one way would be like this:
cd /path/to/directory/with/images/ convert `ls -v -w 1` +append /path/to/output/file.png # this assumes the images are named in alphanumeric order
Once you have your image strip,
Apply the array modifier on your film object.
unwrap your film object with U > Project from View (Bounds).
which unwraps the strip nicely, provided your original array object matched the aspect ratio of the image sequence:
Add a simple material with the strip as a texture:
