“Save modified assets”, or “save as morph” with same name, can overwritte setting of parameter, in data morph.dsf.
But you can save Actor (genesis) as scene subset with keeping each property setting without overwrite data dsf.
When you need zero morphed Genesis with no limits morphs, (or original setting=min -2 max 2 etc)
after change property limits, then save the Actor as scene subset . It do not overwrite morph dsf file.
so taht it is safe.
But unfortunately,, if you apply another character preset, it usually return your morph setting,
untill you save modified assets and record the setting in dsf of data directory.
About save as property preset, (And I thought the preset is expected for such purpose)
it can not work, it only record current value in the duf.
if you set minus value,, and save as property preset,
then apply the property preset,, ds ask you change limits or not,, .and can apply the minus value.
but can not record and load your original setting about the property.
I think property preset may need to work for such purpose too.
(not only about value,, “each original setting of parameter”, as preset)
