You can connect to Second Life using realXtend viewer. It is not at its best that way, but still there are some nice features worth writing about. Another smaller yet interesting feature is that it is possible to import and export the avatar appearance.
You can connect to Second Life using realXtend viewer. It is not
at its best that way, but still there are some nice features worth
writing about. One of them is the possibility for inter-grid
teleporting, as I wrote in teleporting with realXtend. Another smaller yet
interesting feature is that it is possible to import and export the
avatar appearance.

Many people have spent a lot of time in tweaking their avatar
appearance in Second Life. SL Avatar has 144 settings:
- Shape, 77 settings
- Skin, 26 settings
- Hair, 39 settings
- Eyes, 2 settings
Bringing your avatar to OSGrid is clearly a non-zero effort.
Using realXtend appearance import/export, the work is made
significantly easier.
The export gives you a XML file that can be saved to a local
computer (it is actually just a text file, not xml
inside). You need to have "worn" bodyparts and clothing on
when using the import and export facilities. Textures keys are
exported but currently not able to be imported, because different
grids will have different keys, and there is no way to match them
up.

To Export:
- Start editing your appearance
- Click the Export Button,
- Select a file name for the saved data
To import:
- Start Editing your appearance
- Click the Import Button
- Select a file with the saved data
- Make changes to textures
- Click SaveAll Button
This is tested from Second Life to OSGrid, and to a standalone
Opensim. Textures need to be upload separately and set manually.
Many thanks to Ewe Loon for the code patch!
Note: The avatar appearance import/export works in Opensim and
SL, not with the realXtend's own free form mesh avatar. realXtend's
own avatar is stored on a separate server which makes it easy to be
used at different realXtend servers (ie your avatar travels with
you when you teleport around), which makes this kind of
import/export unnecessary.
The avatar appearance import/export can also be used
to back up your sl avatar easily or you can even send
your sl avatar settings in email.
