I like a script to save some user data into the current open blend file. Is there a special data structure for this? Another idea is to create an empty somewhere and write the data into this object. But I think there’s better solution…
The registry is saved in the blend file. It’s for case where the script is keeping data usefull to the current project. To save general data used in all .blend file, you can save/load from a text file in the bpydata folder. There is now toolsl to do so in the current cvs version.
