I met same genesis body explosion in 4.5 rc2 as old saved . daz sceen.
when I load so simple girl genesis jsut pozing ( shaped some morphs)
scene in ds 4.5, the body were parted away.
and I can not find precise way to avoid or correct it. and I could not find what cause the change giometry.
as for me almost of my old daz.scene before I saved in 4.0.3 could not be reused.
at that time , I thought this problem might happen when ds 4.5 CMS,can not find some handmade morphs for genesis
which saved in genesis folda.( I lost or change or overwrite somewhat,,)
Now I want to check it again in 4.5 rc but many of us can not use both of 4.0.3 ver and RC3 same time, in one pc.
with one daz data folda.
so if you can find the cause of exprosion, memorize here please.
I feel it is important to find when the exprosion must happen.
I knew some (not a few) men meet same problem about ds 4.5 (rc1 ,2,3) and mentioned here.
Some of us should forgot or put off about RCver (which may have many new improvements)
then truned to 4.0.3 because of the figure exprosion I think.
