#### 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 setDoorDir(), 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.
