I found a workaround ! In order to make it work you need to backup the poser 13.2.5.... start exe, then replace it with the Poser 13.1.5.... exe this at least makes the Volume features work again. you just get the version nr 13.1.5 on the splash screen but it runs as 13.2.5 fixing the new issues. Something went terribly wrong with the last Poser update that is a sure thing !
