"Epic Castle" is a nice demonstration of a complex mesh model that can be imported into OpenSim, and saved as an OpenSim Archive (OAR) file that others can load and use. In this instance the castle was created and freely released by Epic Games to demonstrate the Unreal Engine. It was imported to OpenSim and provided as an OAR for others to enjoy by Cuteulala Artis. She scaled it for a single 256x256m region, but notes it needs to be scaled up (perhaps onto a 2×2 area or 512x512m varregion) to allow better scaling and so avatars can get through the doors. * https://www.unrealengine.com/showcase/epic-citadel * http://en.wikipedia.org/wiki/Epic_Citadel * Cuteulala Artis's blog post about the OAR on 5-Dec-2012 - http://forums.osgrid.org/viewtopic.php?f=20&t=4840 * OAR download: http://www.2shared.com/file/NwSXYq7l/epiccastle.html * An OpenSim build by Leora Jacobus using the Epic Castle, scaled by 1.5X, providing building interiors and permissions to copy is on OSGrid at Medieval Castle/147/220/81 (as at 24th July 2013)
