    Ja, nemsokára lesz RayDiffuse 2.0 Maya 4.5-re. Elég sok újítás van benne:


    Features

    Soft Diffuse Shading
    Designed to mimic shadowing from global illumination, RayDiffuse captures
    the soft look of shadowing from environmental sources such as the sky.

    Ambient Occlusion Lighting
    : v2.0 includes a new light node that allows lighting of a scene using the
    ambient occlusion method developed by ILM for recent productions.
    Ambient lighting is calculated using an environment map, allowing for quick,
    accurate fill lighting captured on-set via a chrome sphere or spherical image
    [similar to HDRI methods].

    Texture Baking
    : Bake intensive calculations to texture maps for use with Maya or external
    renderers [eg. RenderMan]. Now supporting arbitrary node baking,
    any Maya shading node may be baked including many third-party plug-ins.
    RayDiffuseLight calculations may also be baked to allow integration of ambient
    occlusion lighting into non-raytracing renderers or real-time systems.
    Calculations can also be baked to polygonal per-vertex data.

    Frame-Coherent Sampling
    : v2.0 now supports per-frame consistency for shading calculations,
    ensuring stable performance across multiple frames resulting in animations
    with little or no variation in grain.
    NOTE: Due to architecture differences in random number generation,
    frames rendered on different OSs should not be inter-cut.

    Occlusion Data Output
    : Ambient occlusion data may be rendered or baked out as image maps
    for use with external renderers or real-time systems [eg. RenderMan
    shaders can make use of this data to direct environment map sampling].
    Included is a RenderMan shader detailing how to accomplish this.
