Until now, the global settings have been implemented as Blender properties, more precisely as scene properties. This is necessary in order to be able to display and modify the properties in the Settings panel. However, there is a serious drawback. If you have saved a start-up file, it will be loaded after the Daz importer has been initialized, and if the start-up file contains the scene properties used by the Daz importer, those values will be overwritten. So it does not help if you press the Save Default Settings button. The next time Blender is started, the new default settings are loaded, but they are immediately overwritten by the values in Blender's default start-up file.
|Saving a startup file|
Note that there are no Load/Save Default Settings buttons. This because all changes are persistent, so the default settings file is automatically updated when the settings are changed. The next time you open Blender, the updated settings are loaded.
The new settings system should be compatible with the old one, but since quite a lot of code is affected, there might be some glitches that have to be worked out.
