Guys - first, thanks for cranking on Away3D - it is getting better and better!
However I have observed that when you set bothsides = true for a Plane primitive, Away3D does not correctly render the shading on the back side when using the DirectionalLight3D and the materials PhongColorMaterial, ShadingColorMaterial, PhongBitMapMaterial, or WhiteShadingBitMapMaterial. To be more precise the ambient property of the light has an effect, but the diffuse and specular properties do not. Similarly, if you show a Cylinder primitive with openEnded = true and bothsides=true, you can see into the cylinder, but the wrong side of the inner surface is lit by the diffuse property of the light. Has anyone else noticed this, or am I doing something wrong here? (Entirely possible!) I am using Away3D for interactive technical illustrations and am creating my own simple primitives based on Cylinder etc. but need the inside surfaces to be properly lit (shadows aren't needed - just shading is fine). Thanks! Ralph
