MasterJ,
In blender go to Properties>Scene>Ogre Settings
From there you can configure your paths and save the config file. You
just need to point TUNDRA_ROOT to where you put it on G:/
http://blender2ogre.googlecode.com/files/b2ogre-0.5.5-preview11.zip
new in preview11, Tundra real-time streaming over UDP, object position
and scale are dynamically updated in Tundra.
