Forest Pack Pro 6.0.0

New Features and changes

  • Added support for V-Ray Next beta 1.
  • New memory management system. Scattering performance is increased up to 150% with large distributions.
  • Improved stability with V-Ray IPR.
  • Faster load of V-Ray and Corona proxies.
    • Viewport now uses a quick draft of the proxy, instead the full mesh as before.
    • Note: To use Point-cloud with Corona proxies, it’s necessary to set the Proxy Viewport method to «Full Mesh».
  • Updated UI
    • Added General->Settings icon. This button lets you to configure global settings for all FP objects, including:
      • Visible Rollups. Lets to hide Forest rollups from the Modify panel.
      • Disable Popups (moved from the General rollup).
    • Group Boxes are collapsible. State is global and saved between Max sessions.
    • Resizeable lists (such as Geometry List). State is local to each Forest object and saved with the scene.
    • Added new Icon mode to Creation panel.that lets you to create an empty Forest object, and edit it later from the Modify panel.
    • Added item tooltip to the listboxes. Put cursor over an row to see the full item name.

    • Image, the default mode in previous versions.

  • Effects
    • Added attributes for Particle Flow distribution: particleAge, particleSpeed.
    • Added a generic property to the items in Tree Editor: User ID.
      • This value can be edited by the user and read in Forest Effects, for any use.
      • Also it’s used for some special purposes. For example, in Distribution->Path mode it stores the item counter along the path.
    • Added new transform attributes:
      • «fpItem.xrotaxis», «fpItem.yrotaxis», «fpItem.zrotaxis»: rotation of Forest Item expressed as a system of 3 vectors.
    • New Parameter types: Texture maps and Curves.
    • Multiple effects per Forest object.
    • Added new Effect attributes for new paths mode:
      • distPathPos: Normalized position of item on path (Distribution by Path only).
      • distPathTangent: Tangent vector of path on item position (Distribution by Path only).
    • When fpItem.geomID is greater than maximum ID, result is the remainder, not the maximum value as before.
    • 30 Effects added to the library.
  • iToo Software Update Manager
    • New manager for downloading, installing and managing Forest Pack content including libraries, presets and effects.

    • New vertical walls presets
    • 13 new distribution maps.
  • Raised Distribution->Max.Density default value (from 20 to 40 mill.)
  • Improved viewport performance with Camera features.(When camera changes, Forest is updated only is some Camera feature is used).
  • Added Maxscript function: getSelected(). Returns indexes of items selected on Custom Edit mode (array of integers).
  • Material->Forest Shader parameters are removed from the interface. These are used only for billboards in Mental Ray and if needed, you can modify them from Maxscript as: fastopac, tracedepth, opaclevel, selfillum, irradiance.
  • Appended source name to Library objects imported in the «forest_templates» layer (i.e. «_forest_library_H4AXKAQ_birch_01»).
  • «Tree Editor» is renamed to «Items Editor«. Replaced other references from «trees» to «items»
  • Added Display->Point-cloud Style: Small or Large Dot. Value is global to all Max scenes.
  • «Camera->Limit to Visibility» and «Look-at->On» are off by default.
  • Main Forest folder is moved from «C:\Program Files (x86)\Itoo Software\Forest Pack Pro» to «C:\Program Files\Itoo Software\Forest Pack Pro»
