There's the freebie Meshtastic and a commercial version on SL Marketplace whose name escapes me but is somewhat more performant. I suspect that neither would function on the scale you require though.

There is a reason for this. One of our projects (two OpenSim regions) was seen as good background for a TV production. Now the producers need those buildings in a standard 3D format to upload to their CGI software to do special effects. Since all those objects (except for one or two sculpties) only exist as OpenSim prims, how can I export them to, say, .OBJ, Collada, .DXF, or any similar 3D format? OAR/IAR are really just meaningful in the SL/OpenSim world. They're completely meaningless for any other 3D software, because they're so closely tied to the way SL/OpenSim store prim/mesh data. I found a reference back in 2010, where some people had some limited success using GLInterceptor with the OGLE plugin (the website for OGLE has been down since mid-2010, but there are still ways to get copies of it). The idea is the following: when the SL Viewer generates the mesh data for a scene, it sends OpenGL commands, which get intercepted by GLInterceptor, and are written on a file. OGLE apparently "recombines" those commands so that they are mapped to object meshes, which can be saved to any popular format. This allegedly works for simple objects, but I really have no idea — because of the possibility of content theft, all information regarding "success" with GLInterceptor/OGLE is really not much available. Obviously the best solution would be an OAR/IAR-to-OBJ conversion tool, but if such a tool exists, Google cannot find it :) I suppose it's something worth developing one day, but it would take far, far too much time. As said, the way objects are described in OAR/IAR make little sense outside the SL/OpenSim context. Turning them into real mesh data, in whatever popular format, is a highly complex operation — in effect, it amounts to developing a 3D renderer from scratch that works on SL/OpenSim data! As you all well know, almost every SL viewer out there uses the LL rendering engine. Radegast is one exception. Does it save objects to .OBJ? So... I know that most of you are only worried about the reverse problem (how to get your fantastic 3D models uploaded via mesh import into OpenSim), but I wonder if anyone actually had the need to do the reverse operation — build in OpenSim, export to .OBJ — and, if so, what tools were used to accomplish that feat? It would be a pity to be forced to recreate everything from scratch :-( Not to mention the time it takes... Thanks in advance for any input! Cheers, - Gwyn -- "I'm not building a game.
