I have tied to use wall subtype debris and outline out in the join between scraps The_Ashes_SeriesScPl7 and The_Ashes_SeriesScPl8 however I am still getting a triangle of clipping that seems to ignore the debris wall? The data is available at http://mulucaves.org/SVN/Ashes.zip I have included the pdf, incase it is something to do with the machine I am generating it on. I am using Win2000 with acrobat reader 7. Also scrap The_Ashes_SeriesScPl7 is under The_Ashes_SeriesScPl5, but it does not seem to be faded, I have changed the config, but it seems to make no difference. It works for other scraps in other parts of the cave Thanks Andrew -- No virus found in this outgoing message. Checked by AVG Free Edition.
