Changes since Pathfinder 2021.2.0525:
- Added attractor objects that can temporarily or permanently change an occupant's behavior based on location. Documentation
- Added new ending actions for behaviors including "Remove Occupant", "Wait Until Simulation End", and "Resume Prior Behavior". Documentation
- Allowed ending actions for behaviors to be added at any time - will replace existing ending actions.
- Reduced the number of clicks to create some behavior actions.
- Improved the usability of dialogs where a set of items is specified, including a new search field and the ability to only show selected items. Documentation
- Improved the usability of dialogs where a distribution of items is specified, including a new search field and the ability to only show items with non-zero distributions. Documentation
- Improved simulator threading performance, reducing simulation time 15-25%.
- Added editor support for advanced material features, including normal maps, parallax maps, and PBR materials. Documentation
- Imported texture coordinates on CAD objects are now retained when changing the object's material.
- Added a right-click option to imported CAD objects to remove imported texture coordinates and use default coordinates instead.
- Significantly decreased loading time for models with many complex rooms and doors.
- Adjusted icon spacing in the navigation tree.
- Removed white space padding in CSV output to improve compatibility with 3rd party tools.
- Fixed a bug where occupants could become stuck in double deck elevators.
- Fixed a bug where double deck elevators would close early if occupants finished loading the lower elevator room before the upper room.
- Fixed a bug where occupants might not plan a straight-line path in some models.
- Fixed a bug where occupants might fail to use valid ramps or stairs when component restrictions are enabled.
- Fixed a bug where implicitly deleting a room by overwriting it with another would not remove the room from component restrictions.
- Fixed a bug in the *_summary.json output file where global min/max statistics were listed for each profile/behavior statistic instead of the profile/behavior min/max.
- Fixed a bug that could cause a crash in models with assisted evacuation.
- Fixed a bug where Pathfinder would crash if an attempt was made to delete something from an empty list of scripts in the script editor.
- Fixed a bug that could cause a crash when there was an error with the snapshot's file path.
- Fixed a bug that could caused a crash when running testsim.bat from a command line in international locales.
- Fixed a bug that caused the text in the "Creating Contour" dialog to be cut off.
- Fixed a bug where textures with 16 bits per color-component would show incorrect colors.
- Fixed a bug where occupants referenced a behavior that was not in the model.
- Fixed a bug when specifying an occupant source flowrate or speed profile where the graph might not display correctly.
Changes to Results:
- Added movie export in the MP4 format using either Nvidia's hardware encoder or the OpenH264 software encoder Updated Documentation
- Added 360 movie export via the "Create 360 Movie" menu item Documentation
- Added support for enhanced subpixel morphological antialiasing (SMAA), which in most cases is much faster than the existing multisample anti-aliasing. Documentation
- Added a setting to enable Image Based Lighting, which uses skyboxes to light the scene. Documentation
- Added support for rendering advanced material features.
- Added ability to rename 2D Plots.
- Fixed a movement delay that could occur when changing directions with the keyboard using the roam tool.
- Fixed a bug where Ctrl+S could not be used to save the visualization file when using the roam tool.
- Fixed a bug where built-in circular tour doesn't tune to simulation end time.
