What's new?

Tech Preview: New Hybrid solver

What’s changing

This version is intended as a technical preview of the new hybrid solver.

The hybrid solver solves the dynamic simulation issue using both direct and iterative methods. This is demonstrated via a novel Generalized Hybrid Solver extension and new Fast Friction parameters for dynamic materials and material pairs.

The generalized hybrid solver has some limitations. Before activating it, read the documentation carefully.

Why it matters

The standard solver in Vortex Studio uses a direct method. The direct method is more accurate, but it can get slowed down drastically for content containing many contacts with friction. An iterative solver can be faster for such use cases, but at the cost of lower fidelity.

Contacts Debugging Improvements

What’s changing

Contacts can now be selected in the 3D view of the Vortex Editor and their values inspected in the Properties panel.

A legend has been added in the 3D window that describes the different contact colors and modes.

Why it matters

This feature can be especially useful when debugging erroneous contacts between two geometries such as the contacts between a wheel geometry and the terrain during simulation.

Customization of the Operator Interface of the Simulator

The Vortex Simulator operator window was updated in 2023.11. The window now supports new page categories as well as multiple pages under the same category.

Why it matters

This feature provides more flexibility to content creators when customizing the operator’s window pages.

The Vegetation Library is no longer available

What’s changing

Vortex Studio no longer supports the vegetation extensions and modules, leading to warnings when loading content that uses them. It is safe to remove these extensions and modules from the system.

Why it matters

The vegetation library could not be updated when updating rendering technology. It is suggested to create simple collision geometries for representing vegetation, and to utilize a 3rd party rendering engine for visualization in a simulator context.

System Requirements

License Requirements

Starting with Vortex Studio 2023.7, no license is needed to run a simulation of content created with Vortex Studio Editor (or purchased from CM Labs).

"Running a simulation" is available on any single computer, allowing the use of applications like Python, Unity, or Unreal to run Vortex Studio content regardless of the operating system, as long as it's supported by Vortex Studio.

Vortex Studio Create applications, including Vortex Studio Editor and Vortex Studio Debugger, still require a license.

Whenever a Vortex Studio Activate feature is used in a simulation, a Vortex Studio license is required.

Supported Platform

Windows

Vortex Studio 2024.1 runs on the following platforms:

  • Microsoft Windows 10 (x64), version 22H2. 

  • Microsoft Windows 11 (x64), version 22H2. 

Linux

Not all features are available on the Linux operating system. See Features and Capabilities Overview for more details.

2022.8 is the last version supporting CentOS7 or equivalent.

An update to the latest Ubuntu LTS and equivalent operating systems is in progress.

Currently, Vortex Studio on Linux can only open content created on Vortex Studio (Windows) 2023.3 or earlier until this issue is fixed in a later release.

Using an earlier version of Vortex Studio on Windows to create content still works on Linux.

Hardware Requirements

  • CPU Intel i7-9700 or better

  • RAM 32GB

  • GPU minimum 4 GB of VRAM with Vulkan 1.3 support

    • Nvidia GeForce GTX 10 series or later

    • AMD Radeon RX 5000 series or later

    • Intel UHD Graphics 600 or later

Any computer running Vortex Studio Create or Activate must support AVX2 instructions set.

Known Issues in Vortex Studio 2024.1

Summary

Workaround

VP-41437

When a sound is created such that the listener and the emitter are exactly at the same location, or the listener is moving together with the emitter such that it is precisely above it, the sound that the operator hears becomes garbled. 

This happens for monaural sound track when the listener and the emitter are moving in tandem while being either too close or aligned vertically. The workaround is keep the sound emitter and the listener separate and make sure they can't be move in a way where they could align with each other.

VP-43810

Memory blocks dumped, when terminating the application. 

None. This memory leak is not growing, it's memory that should be returned before the end of the process. Requires a 3rd party update.

VP-44315

Memory leak related to VxContactMaterial when there is a contact upon termination of a VxCore application.

Removing all parts and collision geometries before destroying the VxUniverse ensures that any ongoing contact is invalidated before destroying the VxUniverse. Optionally, using the higher level VxSim API and loading content created in the Vortex Studio Editor seems to work around this issue as the content is automatically unloaded before the application is destroyed.
