Of course it is supported by OSG, another matter is if the exporter takes that into account. For the double-sided thing, I think you could get that just by adding a FRONT, BACK or FRONT_AND_BACK into the material definition components in the .osg file. However, even if you want a geometry that can be seen from the inside and the outside, I recommend you to use thick objects, that is, to use a thin cube for a wall instead of a plane, for example. Sometime ago I read about performance penalties when dealing with double sided materials. I don't know if they still stand. > So when I flip the normals in Blender, is there a way to export it > that way? > I tried to do that as well but I couldn't succeed. You should write a visitor that inverts the normals for those selected geometries. -- Alberto _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
