      • Only the following maps have associated a Filter:
        • Color, Specular, Glossy, Bump, Opacity, Light, HyperTexture, Volume, Metal.
      • Here we are the Filters which are implemented:
        • BitMap: To map an Image around an Object.
        • Noise: Use a Noise.
        • FallOff: Use linear change dipending on the angle between the Object Normal and the view Vector.
        • Mixer: Thanks to this Filter is possible to mix two or more filters for obtaining different results.

      • It’s a negative value through which you can obtain new casual theme ever different and it’s useful to apply the same theme to noise filters of other maps or materials easely.
    • Add the Adaptive property to all the distribution algorithms. Thanks to this you can improve the quality at disadvantage of a soft increase of time.
  • Interface changes
    • Improved the material maps management.
      • Now the maps, for need, can be reached through the node detail of the material.
      • Thanks to the new Preferences menu voice "Split Materials from the Scene", you can use two main work modality to management the material detail:
        • Voise checked: The Scene-Tree is split in two parts: Scene and Materials. Just use the respective tab to navigate into. The first tree is like the old version except for the properties of the selected material that does reference only tho the old "general" tab. The second instead concern exclusively the materials of the scene and is possible navigate into the maps and filters nodes.
        • Voice unchecked: The Scene-Tree is only one, and the material detail is integral part of the Scene-Tree.
    • Finally if you drag an Scene-Tree element this will automatically scoll when it approach the area boundaries.
    • In the inside of the rendering window you can find two useful informations: Elapsed Time and Estimate Time.
    • For all the properties:
      • Now you can insert negative values for the Range types.
      • The Double-Click into the property raise the event click of the respective button.
        Just click two times to activate a list, or a colors browser, etc...
      • Now many properties accepts decimal numbers (ex: the object rotations).
  • Code changes
    • Many of the CN3DMaterial properties and methods are moved into the Filters.

      • NO2 -> Now3D Object Format file 2.
      • NM2 -> Now3D Material Format file 2.
        (Be patient for a document more detailed)
    • Deleted the material property: Reflection Type now when you load the old file format scene this property will be changed in a FallOff filter with the respective FallOff Type.
    • Deleted the material property: Metal FallOff this property is been changed in a simple FallOff filter for the metal map.
    • Deleted the noise filter theme informations: NOISEPERMUTATION, NOISEWAVELET. Now to save the noise use the value: Seed.
    • The N3DProperties control:
      • HeaderWidth: Thanks to this is possible to decide the percentage (1-100) of width for the description respect to the value width.
  • Attention
    • When you load an old scene with noise use for the maps and you save it in the new format will be loose the original "theme".

        • Enable: This property enable the photons elaboration.
        • All the Scene: To use the photons elaboration on all the scene, also on those objects which have materials with the "Use Photons" inactive.
        • Detail: Thanks to this property we can decide the number of photons to fire for each light of the Scene (Be carefull! The details above to 50000 are usable just after the "N3DPhotonsPack1" installation).
        • Threshold: It is equal to the number of photons to use for obtaining the actual intensity; the caustics are smoother if the number is high.
        • Intensity: The Photons intensity.
      • Material properties:
        • Use Photons: To be of use to qualify each material to the caustics elaboration if the Scene property "All the Scene" is setted to "False"). To use it for those materials which have to "transmit" the caustic (ex: glass , mirror, etc...).

    • PlugIn ObjByPath : Now the Translate works fine.
  • Additions
    • Relative Path: Now the images files path have been saved in a relative manner as for the Scene directory. This means that if for example you insert a scene in "C:\Scene\" and the textures in "C:\Scene\Texture\" the if you move the Scene file will lose the images references, because you need of a Folder called "Texture".
    • Polygon Subdivision: It is an object elaboration and it is useful for increasing the polygons number of a Mesh. At the moment, it is limitative, but it could be improved (one day).
    • Adding Hierarchy Type: It is a Scene property and it serves to control the addition modality of an object to a hierarchy. If you choose "Global" than the object to add (when it is possible) will stand at it's position and direction, while if you choose "Local" it will be a change of coordinates and the child object will acquire the "Father" absolute coordinates.
    • Environment Wide: Now exist two new property ("Environment Wide", "Probe, HDR Wide") thanks to is possible to have a greater control on the environment wide map used. For examples, if you have just an environmental map of the Upper Hemisphere (ex. as sky dome) you can settings the "Environment wide" to "180° upper Hemisphere". Of couse, these two new properties have been added in all using types of environmental maps: Scene Environment, Material Environment, Reflection.
