Ok I looked in my dson importer log txt file (in Poser top menu, do: Scripts > DSON Support > Importer Preferences > Log File - Show )
I noticed it writes out to a path, find a line that says:
“DSON Write Path: D:/PoserContent/!Main/Runtime/DSON/auto_adapted”
See what path it writes to for you.
I went to that path and saw in the content_files subfolder it creates multiple Genesis.cr2 !!! So you might want to do a search under that folder (including all subfolders) for Genesis.cr2 and delete them all and force the poser dson importer to write a whole new one…
Also delete any .pmd files (binary morph collection files) it might have left behind in that path under the data\DAZ 3D\Genesis\Base subfolder
If this works, we need a feature request for DSON Importer to purge cache maybe…
edit to add: also check out the actual cache folder as shown by Poser top menu, do: Scripts > DSON Support > Importer Preferences - Cache Folder
see what’s under there… mine was clean.
