Sometimes my application has to load models that have normals not always oriented in the same coherent way, so it is not always possible to say that a surface is oriented in a way or in another and my renderings do not look correct.
I'd like to fix this problem in some way...so I was thinking about rendering both front and back faces, but how do I ask OSG do this? Or perhaps, is there another way/technique to achive the same result? (ie. orient a surface in a coherent way: all faces inward XOR outward) Thank you. Alessandro
