Hi again, i have tryed out to add new materials on each face and only changing Material.DoubleSided property
both before and after geometry initialization inside silverlight enviroment (with invalidation and / or call to CalculateNormals)
anyway it works allright for testing, will you implement af possibility to set color / material on the black side of the faces in future releases ?
I have also tryed to add flipped faces to the geometry programatically, but this way seems to ignore the light,
could i be doing something wrong here or is this not possible yet or in future release ?
