7、 HD Terrain Server Update

7.1 Function Optimization Explanation

At present, the vehicle chassis point query also supports low-pass filtering. This allows the surface used for vehicle chassis point queries to be filtered like tire queries.

The connection between TerrainServer and Siemens tires (MF Tyre/MF Swift) is now available.

Now Terrain Server provides an evaluation version, which can not only use individual points for body queries, but also use small rectangular areas on the vehicle for body queries. Point queries: Traditional vehicle body queries are based on the position of a certain point, usually used to represent certain specific points where the vehicle chassis contacts the ground; Rectangular Area Questions: This evaluation version has added a feature that allows queries to be made using rectangular areas on the vehicle's chassis, rather than just using a single point. This means that queries can be conducted within a certain area of the vehicle to more accurately simulate and detect the interaction between the vehicle body and the ground;

Improved the handling of TerrainServer's inability to allocate sufficient memory to load tracks. For more information, please refer to the rFPro Terrain Server User Guide.

8、 Scene Editor update

8.1 New Feature: Library Panel

Importing objects from a library (such as the rFPro object library) becomes more intuitive:

Added a library panel that can switch displays from the View menu. This panel contains a list of objects in the library, displayed in thumbnail format according to their respective categories.

These objects can be directly dragged and dropped into the open scene.

In addition, items in the library can be added to the Plant list and set random weight factors, as well as optional random scaling and rotation offsets. When Plant mode is activated, clicking on a position in the scene will plant an object from the list.

8.2 Other Function Optimization Instructions

Export selected objects as rFPro meshes (. gmt and/or gMesh) and textures (. ddds) to a specified folder, allowing users to extract and import objects from one scene to another, even if the object was originally located in Inside the MAS compressed package. You can now create and edit. usercfg files, providing additional startup location options without the need to manually create or edit the file.

When selecting an animated object (such as a pedestrian), the skeletal structure can be displayed and the skeletal names, positions, and parent skeletal information can be exported as a CSV file, which is helpful for users who want to control skeletal animations through APIs. Users can select a bone from the list, which will be highlighted in the viewport.

When loading a vehicle in Scene Editor, lights (such as headlights) will be displayed in a hierarchical view and can be edited. At present, complete vehicles cannot be saved, so users can save these settings as IncludeFile and manually link the new settings to the vehicle's. gen file. Consider providing the ability to save complete vehicle settings files in future versions. When rendering the current or top view as an image file, output resolutions exceeding 4096 pixels are now supported.

The FBX import module has been optimized and improved as follows:

Add an option to scale the physical dimensions of objects from centimeters (cm) to meters (m) instead of setting the scaling factor to 100.

Add an option to merge nested instances into a single object to prevent bugs where deeply nested instances may not be recognized.

The Python scripting API has undergone the following improvements:

The Spline class has added InterpolateNSegments, InterpolateByLength, and GetPointsDistanceApart functions to finely control the interpolation method of spline curves, such as for placing object chains with fixed sizes along Bezier curves (such as fence panels);

Added the CloseScene() function inside the script; Added the RenderCurrentViewToImage and RenderTopViewToImage functions in the Scene class, allowing the current or top view to be output as an image file from a script. It should be noted that this feature requires a GUI graphical interface and is not available in command-line mode.

The Command Line Interface (CLI) has undergone the following improvements and fixes:

Set the - import option to optional, allowing Python scripts to sequentially call OpenScene() and CloseScene() multiple times.

Added explicit - open<in>and - save<out>options, along with the existing - import<in><out>, to the command-line interface.

Function fix: User response in the command-line interface may sometimes be ignored.

Other general function improvements, optimizations, and fixes:

When saving a single updated grid as a new file, the new file will not be created, but the original file will be updated.

When importing an OBJ file, a dialog box will appear for the user to select the original coordinate system.

AIW FastPath is now visualized through white corridor segments up to the vertices. It can also be converted into spline curves and then converted back, allowing users to edit.

Now, when closing a scene or application, users will be prompted to save unsaved changes instead of always asking if they want to close the scene. Can display a list of changes for users to view.

In situations where it is not applicable, the relevant operations will turn gray and unavailable, such as when there are no undo/redo operations.

The HAT Snap options will always be enabled as they can be used with Gizmo (holding down the control key and Shift key).

Only the parameters of the camera will be saved to the. cam file.

The default width of spline curves is 0.1 meters, making them easier to view and select.

When loading the vehicle, 'Rendering False and Shadow Objects' will be automatically unchecked, hiding the collision mesh and NoRainZone.

The driver animation is now displayed correctly, instead of showing the driver's T-shaped posture.

Removed unused ViewBox lines from the rendered. txt file.

Fix: The 'Render False' and 'Shadow Objects' menu options will not be saved in subsequent scene editor sessions.

Fix: Objects marked as movable will not be automatically marked as collidable.

Fix: The opacity setting for spline curves does not always take effect.

For more information, please refer to the rFPro Scene Editor User Guide.

9、 RFPro Traffic Update

9.1 Replay Server Function Optimization Instructions

The Replay Server client and API can now automatically start replaying sessions at specific simulation time values and repeatedly restart the session during the activated simulation process. And fixed the issue in the replay plugin that may cause stack memory damage.

For more detailed information, please refer to the Replay Server UI and API.

9.2 Replay Server Function Repair Instructions

Fixed the display issue where ReplayServer sometimes automatically creates transparent vehicles.  

9.3 SUMO Traffic Plugin Function Repair Instructions

The SUMO plugin of rFPro has now been updated to interact with SUMO using the SUMO TraCI API in version 1.20.0. This API has now been deprecated and a warning will be printed when the plugin starts. We are investigating alternative APIs for interaction with SUMO in future versions.

If the PLR setting "AI Force Headlight Synchronization" is enabled, vehicles controlled by SUMO will turn on/off their headlights at exactly the same time.

Problem fix: When there is a gap between the TSS and SUMO networks, traffic vehicles may appear in the air and fall onto the road.

10、 RFPro Core Content Update

10.12kFlat Location

The default 2kFlat layout now includes road markings for the EuroNCAP test layout. The OpenDrive file of 2kFlat_CAP has been renamed to reflect this content change. The previous 2kFlat marking is now available as a scene variant option for users.

10.2Hatchback Vehicle

The color skin textures of all variants have been replaced with the "VehPint" entry in the. veh file, except for Hatchback Camo vehicles. These entries correspond to the "VehPint" reference with the same name in the GEN file, and contain a material name fragment string followed by the red, green, and blue color components in the linear color space. The final value of the "VehPint" entry defines the surface cleanliness level of the object;

Updated the wiper animation for Hatchback_SHD vehicles;

Adjusted the light source definition of the front headlights to be more accurately placed in the correct position;

Improved the display of the tachometer.

10.3 Unbranded Vehicles Pack Transportation Vehicles

All unbranded vehicles now have their own uniquely named wiper animations. At the same time, it solves the warning message that appears when injecting them as traffic vehicles and allows the animation to be different between left-hand drive and right-hand drive vehicles.

Improved the tachometer display for all vehicles.

Fix: Material errors in Saloon models may cause occasional IG crashes during loading. 10.4 Traffic Vehicles Pack

A low polygon version of Unbrand_SUV has been added to rFPro's transportation package.

Fix: The category assignment for FireTruck has been corrected to 'Traffic'.

10.1 Object Library Target Library

Country specific abbreviations now follow the two letter ISO 3166-1 alpha-2 standard country code. This means that any existing scene that references Object Library resources needs to be updated;

A set of rock objects has been added to the static target library;

The soil texture of all parked vehicles has been improved;

The black Labrador Retriever model now uses PBR material;

11、 RFPro external interface update

11.1 Autodesk 3ds Max Plugin Update

We have developed a new CarMaker Extended product prototype extension that can communicate directly with rFPro through a Remote Model Plugin.

11.4 Dashboard Display Plugin Update

Added a SimHub mode for integration with SimHub dashboard software package（ https://www.simhubdash.com/ ）Coordinated use. The image is received in SimHub Memory Mapping File (MMF) format. The functionality of the existing SimHub plugin has now been integrated into the dashboard display plugin.

11.5 VI grade (formal B&K) SimSound update

Added support for sending road index values for each pavement type. This allows SimSound to dynamically adjust road noise levels based on the type of road the vehicle crosses.

11.6 VIOSO Warper Plugin Update

The VIOSO plugin has been upgraded to support the latest version of the VIOSO SDK (1.6.33). 11.7 VTD plugin update

Updated to display a warning message when the VTD plugin fails to receive a message from VTD. For more information, please refer to the rFPro VTD Plugin.
