Ambient occlusion: multiplied with direct lighting by default, add is also still available and more blending methods might be added if they are useful. This is fundamentally a non physical effect. Environment lighting: always added as you would expect (though you can subtract by specifying negative energy). This can be just white or take colors or textures from the world. Indirect lighting: only supported for AAO at the moment (and is still too approximate), and also is always added. A factor is available to specify how much is added, though value 1.0 is correct. Also: * Material ambient value now defaults to 1.0. * Added Environment, Indirect and Emit pass. * "Both" blending method is no longer available. * Attenuation, sampling parameters are still shared, some could be split up, though if they are different this would affect performance.
