I'm using the latest Daz Studio on Windows 8.1.1. The ORIGINAL version of the DynCreator script still works. The update broke it awhile back, but the original file still works. If you've backed up both versions, use that. I just tried it and it's working. Like was mentioned earlier in the thread, sometimes it doesn't work on meshes it doesn't like. I've used it only on cloth made to be dynamic (don't like fiddling with conformers for this) and there's only been one thing that it wouldn't convert.
