Hi,
JPEG2000 isn't quite that unsupported; for details, have a look at
http://www.jpeg.org/jpeg2000/
As the textures are stored as j2k streams in the server, and you can't use
the jpeg-formatted images in the client directly either, even if you would
get them (as for rendering you'll probably

One of the nagging problems we have appears to be memory leaks. There are
consistent and frustrating reports of more heavily used regions using up all
the RAM, then starting swap, then lagging, then freezing every week.
In order to help bring a little clarity to this, Nebadon has put together:

I don't think it's a goal of OpenSim to serve texture assets to web
browsers, nor should it be. Such a move would open doors to texture piracy
and reduce any incentives for content creators to distribute their content
on any OpenSim based platform. Grid operators who would want to serve their
It's really the proliferation of eternal caches that causes issues,
IMHO.

It is a bit sad that this effort goes to waste. The opensim.ini is too
big to be efficient and everyone is wasting a lot of time browsing it
back and forth. I think something like splitting it up or moving
defaults to other file is really needed.
What is complex now is finding the properties you
On the server-side, this can be made configurable, default to false. If
server admins want to serve jpgs, let's let them.
Since this work is being done within the Idealist viewer, a separate
issue is whether you want Idealist to assume the existence of jpgs on
the server or not. But that's a

I was under the impression that the asset server was going to require
authentication regardless. It would be possible to keep track, for
each agent, what textures have been 'authorized' (by being in view).
Remember, we can't protect content in the cache of the client, and the

Hello OSWorld. Just a question about current limits in OS. We are running 4
instances of OpenSIm rev 8810, holding 11 sims on ovh rps-2 (2GB RAM)

still available

My professional opinion is that it is a wild goose chase to try to
protect assets. The unfortunate reality is that when opensimulator
becomes widely adopted there will be open clients and anyone can go
and use them to get someone elses assets. There is just no way to
protect yourself against it.
Perhaps start with baby steps - how about just a simple move to change
opensim.ini.example and opensim.ini default locations out of the bin and
put it in a config folder - I for one am tired of looking for config

There are memory leaks in OpenSim, so restarting every so often isn't an
option. And, you are into swap a little bit there. It seems that recent mono
likes some headroom in real memory and tends to crash when the system hits
virtual memory. You might see better results with mono 2.0.1 in that

Like I mentioned before, I spent some time adapting the SVN trunk of
libomv to OpenSim, so I think I can look into this release, if there is
really an interest to update it.
I will demand my ice cream after I'm done though

I also think that just because a texture comes off of HTTP doesn't mean
security can't be applied.
I can see scenarios to duplicate textures across multiple web servers to
improve downloading performance.
I kind of look forward to the day when I can apply URLs as textures and
