I have a problem with .duf files created from old .daz files. The daz file load normally and there are no problems with that. But when I want to save that scene as a .duf file chances are that they are not saved at all at the first try. The second try creates a .duf file but when I load it a couple of assets are missing. They show up as grey bounding boxes. The original .daz file however works fine.
The content I used in these scenes is mostly V4 stuff. The missing stuff were morphs and clothes. The .daz files were created with a second PC via network but it uses my library and my data folder so I normally can open all files made with the second PC. The only difference is that the second PC runs Windows XP and the 32bit version of Studio 4.5 Pro. My PC works with the 64bit version and Win7.
