/// Impossible to fix with current implementation without tearing down the project and starting over. It seems that the representative plane constructed in teh viewing camera's uvcalc script is causing UV calculations to go awry. If we pushed the representative plane to be back as far as the main camera's interpolated plane, this should calculate correctly. However, I don't know what else this will mess up in my project's logic.
