Hi,
For this purpose, you can use negative values for the Padding parameter - in this case, the Top Padding. To ensure consistent values across all Segments, the recommended approach is to use Transform Operators with the Top Padding Parameter exported and wired to a Numeric Parameter. Please find attached a modified version of your scene (251201_RAILCLONE_TILED_ROOFS_ITOOSOFT_REV.max). I hope this helps.
Best regards,
