I can't remember as I am still sort of mind boggled at the whole WM situation,  but just went  and done the process again from the thread I linked to, not sure if this was what I initially did but here goes...

1. load alyson2 from pp2012 runtime and resave the cr file so i can easily find it, (I hate where they put the files all over the shop)

2. launch MM4

3. load pz2 to prompt more options button

4. load cr of a2

5. click on more options and select delete all morph targets from file

6. open the body section and delete all morphs there

7. save cr as new name

8. load new cr in poser and delete all the group names which i found still showed (not sure if this should have been done in mm4 but they still showed but empty) check other body parts just in case I missed any which I didnt as it was automatic lol

9. open joint editor and zero figure there (legs will correct)

10. rename figure in the property tab

11. optional -  go to material room and unattach all  nodes and select and apply to all, then delete all detatched nodes holding down the shift button so they go from all parts, it will now be completely white with no mats attached, I do this on a lot of stuff so when I retexture and save I dont have any hidden little nodes which will make poser go around in circles trying to find the maps which arent there as I had subsequently deleted (then get that message saying help i cant find it)

12 resave cr file

13 also inject anastasia and resave this as a zerod ana (i also zero using joint editor again just in case)

there is probably stuff i havent done or done wrong but heyho
