It's difficult to say anything specific
without knowing the structure of the data
file and the to3d command line (or
interactive to3d options) that you used,
but my guess is that your functional
overlay has been converted using an
incorrect byte offset. Be certain that
you've specified the appropriate header
lengths as well as the appropriate
image dimensions and binary data type.
