An exact description of how to open a compressed library, extract the file, edit it and copy it back into the library, is almost impossible. It will depend on your system, configuration and tools available. But the general approach would go something like this:
- Open the compressed library, *.sh3f, file with some zip tool
(you may have to rename the file to *.zip temporarily)
- Copy the *.properties file out of the library
- Edit the copy with a text editor to add/change properties.
- Copy the edited *.properties file back into the compressed library.
- (rename the compressed library back to *.sh3f)
- In SH3D, use Import Furniture Library.
But even such a general description may not be of too much use unless you already have some familiarity with how your file system works. In which case you probably don't need the description...
ok
PS Puybaret - I think a way of opening the "raw" .propeties file with/from the FurnitureLibraryEditor might be of help to some (I would use it), but whether it is worth the trouble (or makes sense) from development point of view, I really don't know. (And you would probably need a file back-up and restore procedure for small mishaps
)
