These release notes describe the new features and evolutions available in SCANeR 2024.1 Powered by ne><t.

With respect to the packaging of SCANeR the new features listed in the following paragraphs are regrouped per Pack: 

Bug fixes

This version of SCANeR also includes all bug fixes and improvements from previous releases, including SCANeR 2023.1 , 2023.2 , 2023.3 and customer-specific versions.


New features

           1.Models & Tools

This version defines new concepts for SCANeR architecture allowing better flexibility and improved performance.

In the previous versions, every feature was implemented as a module whereas in SCANeR 2024.1 Powered by ne><t, there is a distinction between models and tools.

This new distinction allows an improved performance and a better handling of the software as, for instance, tools can be launched during the simulation.

Example of the use of tools during a simulation:

           2. SCANeR Architecture

This new version features SCANeR Runtime, an executable which role is to handle the management of data streams, as well as loading the different models and tools needed. It leads to optimized flexibility and performance in every configuration.

As a consequence, Models and Tools do not communicate with each other through the SCANeR network simulation bus anymore but through SCANeR Runtime.

In a cluster configuration, only the different Runtime use the network to communicate with each other.

Thus, network configuration is used only when needed leading to the improvement of the software overall performance.

           3. Automatic model selection

In SCANeR 2024.1 Powered by ne><t, models are automatically deduced from scenario and digital vehicles. This feature allows a way better and easier handling of the simulations as it is not needed to manually select models.

The following video illustrates how the models loaded by SCANeR Runtime vary depending on the scenario selected:

SCANeR road style editor

           4.New time management

One of the various new features implemented in SCANeR 2024.1 Powered by ne><t is a robust time management system featuring an integrated scheduler component.

It allows users to easily switch from a real-time to a non-real-time simulation without needing any extra module. In addition, a clock server concept ensures that it is compatible with a Master/Slave architecture.

The simulation speed can, thus, be modified while the simulation is running as shown below:

The new time management feature allows reproducible parallel computation which was not possible in previous SCANeR versions architecture.



New features

          1.Unified data model

In previous versions, modules were sharing different type of information, thus different type of messages, through either the network simulation bus or using shared memory.

Now, in SCANeR 2024.1 Powered by ne><t, every information shared is stored into a structured data model which can therefore describe the whole simulation.

This new data model concept provides a clearly structured and organized data storage.

What is thrilling with this data model is its unified aspect as it now used by every SCANeR features such as:

  • Mapping (FMU, RTGateway)
  • ControlPad & AnalyzingTool
  • Scripts
  • SDK

The following video presents how the data model makes it easy to access to sensor output in ControlPad for example:

The same information can be accessed in DataConvertor and AnalyzingTool using the same data model:

           2. Unified record format

There have always been two record formats in SCANeR:

  • .gz files provided by SCANeR Record
  • .eg files provided by Modelhandler

In SCANeR 2024.1 Powered by ne><t, these two record formats were merged into a SQL lite result database.

This standard format is structured with the data model presented earlier, and allows an easier data access and extraction as it can be opened by SQL lite compatible open-source tools such as DB Browser.

           3. Data organization

While in previous SCANeR versions the configurations were mixing data and config files, in SCANeR 2024.1 Powered by ne><t, configurations are only related to the simulator/test bench and deal with model and tools assignation on computers as well as specific options.

Furthermore, data is now organized in workspaces.

Workspaces provide numerous benefits:

  • They contain all user data (scenario, systems, KPIs…)
  • They can be located anywhere
  • There is a clear dependency between workspaces
  • They are easy to pack and to share
  • The current workspace is always accessible through SCANeR

           4. Simulation project

We know that some projects may require to compute different simulations from different scenarios. That is why SCANeR 2024.1 Powered by ne><t allows to create a simulation project.

A simulation project is an easy way to organize simulation data. It is standalone, and offers the following benefits:

  • It can contain multiple scenarios
  • It gathers all parameters (models and simulation parameters, KPIs)
  • It is easy to share and to deploy

Finally, a simulation project is also compatible with SCANeR explore and SCANeR compute.

Vehicle Mode

New features

            1. Digital Vehicle Concept

SCANeR 2024.1 Powered by ne><t provides the concept of digital vehicles offering a better and easier vehicle conception. This new digital vehicle concept led to multiple positive changes increasing the software performance and flexibility.

First, the different file formats needed to describe the vehicle information (dynamics, sensors, graphics…) have been merged into a single DVE file format.

In addition, all the vehicle aspects can now be configured from the vehicle mode. It allows to considerably save in configuration time as it is no longer needed to navigate through scenario to add sensors or simulation mode to add custom models such as ADAS.


Due to these new features, the vehicle mode has changed a bit. It contains a lot more parameters, but still offers an easy navigation. In addition, a 3D interactive view allows to better understand those parameters.

           2. FMU Mapping

SCANeR 2024.1 Powered by ne><t demonstrates our improvement in integrating systems such as ADAS.

As stated earlier, everything is now happening in the vehicle mode. Moreover, due to the struggle to access to FMU parameters through RTGateway, we implemented a FMU Mapping editor.

It is a block-based editor allowing a simple mapping. On top of that, the FMU mapping editor uses the data model introduced earlier, thus, any information can be easily accessed as we demonstrated.

UXD ENGINE (powered by Unreal)

Note: UXD Engine is not yet capable of addressing all SCANeR use cases. For this reason, the original VISUAL module, based on Open Scene Graph, is still available.

Unreal Engine 5

Rendering quality improvements

Unreal 5 has been successfully integrated in SCANeR 2024.1 Powered by ne><t, providing some new features which will improve the overall rendering quality.

First, there is Nanite, a new rendering technology. It replaces LOD (Level of Detail) with a new dynamic way of managing meshes.

Two versions of Nanite view in the UXDEngine applied on the map N104:

Another great feature that can be found in Unreal 5 is Lumen, which is a new lighting model for global illumination.

Furthermore, Unreal 5 highlights its new shadow mapping method called Virtual Shadow Map. It is used to deliver consistent and high-resolution shadowing.

Unreal 5 also features NVIDIA DLSS 3.5, a neural graphics technology that multiplies performance using AI, as well as nDisplay which improves the rendering of 3D content simultaneously to multiple displays.
