Hi Cramp, It could be that the tri stripper is bluking at such a large dataset. Try disable the tri stripping via:
osgconv myfile.obj myfile.osg -O noTriStripPolygons You can query the options via: osgconv --format obj Plugin osgPlugins-2.9.0/osgdb_obj.so { ReaderWriter : Wavefront OBJ Reader { extensions : .obj Alias Wavefront OBJ format options : AMBIENT=<unit> Set texture unit for ambient texture options : BUMP=<unit> Set texture unit for bumpmap texture options : DIFFUSE=<unit> Set texture unit for diffuse texture options : DISPLACEMENT=<unit> Set texture unit for displacement texture options : OPACITY=<unit> Set texture unit for opacity/dissolve texture options : REFLECTION=<unit> Set texture unit for reflection texture options : SPECULAR=<unit> Set texture unit for specular texture options : SPECULAR_EXPONENT=<unit> Set texture unit for specular exponent texture options : noRotation Do not do the default rotate about X axis options : noTesselateLargePolygons Do not do the default tesselation of large polygons options : noTriStripPolygons Do not do the default tri stripping of polygons } } Robert. _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
