ModRex is a joint effort between RealXtend and OpenSim devs to make OpenSim aware of RealXtend specific functionality. It will not only enable the best of both worlds, but also speeds up the development of a solid standard for virtual worlds.

ModRex with mesh support, running on Linux

This is still pre-alpha code, so some features may not work.



mkdir /opt/opensim opt/opensim/simulator /opt/opensim/authentication /opt/opensim/avatarstorage /opt/opensim/builds
cd /opt/opensim/builds/8218
svn co . 
mkdir modrex modrex/build
cp -R bin/*.dll modrex/build
cd modrex
svn checkout .
cd ModularRex
vi prebuild.xml
  • Change each ../../../bin to ../../build, and each ../../bin to ../build, save and exit
mono ../../bin/Prebuild.exe /target monodev
  • Open /opt/opensim/builds/8218/OpenSim.sln with MonoDevelop
  • Add existing project > modrex/ModularRex/RexFramework/ModularRex.RexFramework.mdp
  • Add existing project > modrex/ModularRex/NHibernate/ModularRex.NHibernate.mdp
  • Add existing project > modrex/ModularRex/RexOdePlugin/ModularRex.RexOdePlugin.mdp
  • Add existing project > modrex/ModularRex/ModularRex.mdp
  • Change the runtime version for these projects to mono 3.5
  • Remove the broken OpenSim reference in the ModularRex project, and add the OpenSim project as reference

  • Download and build the authentication service
svn co /opt/opensim/authentication
cd /opt/opensim/authentication
mono bin/Prebuild.exe /target nant
  • Create a mysql database "authentication"
cd bin
mono Authentication.exe 
  • Setup authentication
MySql_SqlHandler.dll (or SQLite_SqlHandler.dll. MySql_SqlHandler.dll gives not implemented messages but seems to work ok)
<enter>(logging enabled=False)
<enter>(def. region x 1000)
<enter>(def. region y 1000)
<enter>(default gridurl
<enter>(default dns)
<enter>(dbname authentication)
<enter>(dbuser root)
*******(dbpw for root) (httpsettings LAN-IP)

The authentication daemon should run by now

  • Download and build the avatarstorage service
svn co /opt/opensim/avatarstorage
cd /opt/opensim/avatarstorage
bin/Prebuild.exe /target nant
  • Create a database "avatarstorage"
cd bin
mono AvatarStorage.exe
  • Setup avatarstorage
<enter>(Inventory True)
<enter>(logging_enabled False)
avatarstorage (dbname)
<enter>(dbuser root)
********(dbpw root) (httpsettings LAN-IP)
<enter>(http port 10000)
<enter>(ssl False)

The avatarstorage daemon should run by now

  • Setup OpenSim in standalone mode(Grid is not working yet); add these lines to OpenSim.ini:
  • You can use this rex serverscript to manage and start the services(uses screen)
  • Create a user in the authentication console
create user

the 'Account' part is the first part in your rex-username(account@myauthenticationdaemonuri) Once the three services are running, an initial user was made, fire up the realXtend client with wine and login.

Known Quirks

  • Shift-copy a mesh leaves a prim behind
  • Meshes are persistant only after a clean shutdown
  • Mesh collision doesn't work yet
  • Avatar is stored, but appearance changes only after viewer restart
