As importing has been broken for a long time, I decided to
hijack the existing (broken) buttons of the Appearance floater
for the following new implementation:
The currently selected wearable, if full perm and the agent
is owner (of course) and creator, then that wearable can be
exported to disk with AIFilePicker in the context "archetype".
The used format is now XML, linden_genepool version 1.0, the
same format that is used when saving from Advanced --> Character
--> Character Tests --> Appearance to XML in any viewer.
However, unlike that Advanced option (which normally only
works when DebugAvatarAppearanceMessage is set to TRUE, ie in
the official Linden Viewer; but that does a lot more, most
likely unwanted things: it causes to dump files in this format
to the LL_PATH_LOGS directory whenever appearance data comes
by and other stuff for debugging purposes only), now ONLY the
selected wearable is written to the file. In the case of multiwear
with several layers, that means the selected layer, as well.
When importing these XML files again, only the selected
wearable/layer is overwritten (assuming it is modifiable) with
the data in the file that corresponds to that wearable (if
the file contains data of another wearable then nothing happens).
Note that this file format can be read by blender-avastar:
Using this feature to save the shape you created in SL will
allow you to import that into blender. Likewise, a shape created
or modified in blender can be imported into SL using this feature.
