It's not just you. There are at least two or three bugs involved here. 1) It is a bug that one part of OSG would generate a primitive mode that cannot be handled by other parts of OSG. Indeed, a comparison of .../include/osg/PrimitiveSet with .../src/osgUtil/TangentSpaceGenerator.cpp suggests that there are several primitive modes that could be generated but not handled. With very slightly cleverer coding, the OSG folks could have detected this situation at compile time, and could have fixed it a long time ago. 2) It is a bug in OSG that the error message is remarkably uninformative. The message doesn't say what caused the problem. It doesn't say how serious the problem is, or what might be the consequences of ignoring the problem. It gives no clue how to avoid the problem ... unless you want to download the source and reverse-engineer a large, complex, and virtually uncommented software system. In particular, the message is presumably provoked by some object in the scene, but the message gives no clue as to what the identity of the offending object. 3) It's not clear to me whether this can be considered a bug in FG, or whether changing FG so as to avoid provoking the OSG bug would be worth the trouble. Changing FG would be a royal pain, because of item (2) above. On 04/22/2010 03:12 PM, Tim Moore wrote: >> It would be best to get the polygons out of the loaded geometry.

Installing the latest OSG SVN does not appear to be sufficient to fix the problem. ------------------------------------------------------------------------------ Lotusphere 2011 Register now for Lotusphere 2011 and learn how to connect the dots, take your collaborative environment to the next level, and enter the era of Social Business. http://p.sf.net/sfu/lotusphere-d2d _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
