[Opensim-dev] Texture UUID in XML File

[James Stallings II]

Stephen,

The savexml2 command is an old codepath for backing up regions to files. It
has largely been replaced (in usage, at least), by 'save oar'.

The texture information you see in the xml file, I am 99% certain, is the
text-encoded binary texture data (dont ask me about the encoding method, I'm
ignorant of it).

I rather strongly suspect that the way you are going about this is all
wrong, unless you plan to make changes to these backup files and then reload
them on the region server after the fact. It is particularly unlikely that
you will be able to modify textures in-situ via a web interface using this
methodology. I would suggest that to achieve such functionality you
investigate how the asset server works, and direct your efforts at producing
a web interface that interoperates with the asset server to modify textures
dynamically.

Hope this helps!

Cheers!
