[Opensim-users] On Linux, Latest SL/Opensim viewer not compatible with opensim water...

[Justin Clark-Casey]

The usual approach would be to include these assets with OpenSimulator itself, rather than require people to fetch a 
separate IAR.  So donating a patch for this would be welcome, though of course the assets would have to be appropriately 
licensed.  I would say that they should be identical or very close to the effect expected elsewhere (though, of course, 
any proprietary assets are not appropriate).

If I remember, in the past some of these assets
