December 1, 2021

What's New

This release adds new features and bug fixes.

This version of Pathfinder uses version 1.8.0_302 of the OpenJDK Java VM.

Changes since Pathfinder 2021.3.0901:

  • Added Occupant Targets that allow occupants to reserve, navigate toward, and wait at single-occupant locations in the model, such as seating. Documentation
  • Added an option to color materials by using the object's color. Documentation
  • Added the ability to create a new behavior by double clicking the Behaviors node in the Navigation Tree.
  • Added the ability to assign materials to rooms, stairs, and ramps for improved visualization. Documentation
  • Added the ability to specify a custom directory for backup PTH files.
  • Added the ability to filter Accepted Profiles per Queue and Path.
  • Added vertex information to simulator error messages about shared internal edges.
  • Added API function <code>setDoorDir()</code>, setting the allowed direction of travel for doors.
  • Improved visibility of profile info when specifying per-profile movement group templates.
  • Improved layout of occupant source property panel to reduce empty space.
  • Updated calculations while occupants are moving over stair-like geometry with adjustments to their movement model to improve the accuracy of both velocity and distance. Documentation
  • Updated JRE to version 1.8.0_302.
  • Updated scientific notation to show the plus sign in the exponent.
  • Updated the Orient on point action (formerly the Orient Occupants on Point action) so that empty space can now be selected as the reference point.
  • Fixed a crash that could occur in models with Attractors and Change Profile behavior actions.
  • Fixed a crash that could occur copying/pasting certain behavior actions involving Goto Queues.
  • Fixed a bug that caused queues and attractors to remain visible after hiding the corresponding floor.
  • Fixed a bug where manipulating a room would remove thin walls within the room.
  • Fixed a bug where all materials in the database were being saved to pth files, even if unused. Re-save affected files to reduce size.
  • Fixed a bug where pressing certain keys on the keyboard would activate the Attractor tool.
  • Fixed a bug where the wrong behavior colors were being written to the Results output file when using a Change Behavior action. Re-run affected simulations to fix.
  • Fixed a bug where importing some FBX files might result in an ArrayIndexOutOfBoundsException error.

Changes to Results:

  • Added gamma correction for improved lighting.
  • In the Occupant Proximity Analysis dialog, increased the time that tooltips remain visible.
  • Updated the default value for anisotropic filtering from 16 to 4.
  • Fixed a bug where FDS slices that span multiple meshes were not being grouped or showing the mesh number in the Navigation View.
  • Fixed a bug where FDS boundary output in multiple-mesh models all indicated they were in Mesh 0 in the Navigation View.
  • Fixed a bug where textures might display incorrectly on PyroSim obstructions that intersect holes with control logic.
  • Fixed typos.
