Since you're already using the 'obj' format for the first export I'd add
UV texture coordinates to the 'obj' and convert to mesh with obj2mesh.
If you keep the UV coordinates the same for different sizes of the cube
you will get the same mapping effect.

Using the basic Radiance texture mapping I think you will have to
scale the texture along the z-axis to get the effect you want. That
requires a new material definition for each frame you export.
