  Important:

  Linux dependency for Render Node - If working on a Linux machine, set your local directory to /var/opt/Autodesk with write access on the Linux machine that is running the VRED 2020 Render Node.

New Features and Enhancements

For the new features and enhancements in Autodesk VRED 2022.3 products, see What's New in VRED 2022.3.

Fixed Issues

These are the issues we fixed in VRED 2022.3 products:

Animation

• Auto-generated Curve Frame Length - Auto-generated animation curves for image sequences are the correct length when the first image doesn't end with 0.

Asset Manager

• Multi-material Saving - Saving multi-materials (Multipass, Layered, or Switch materials) will no longer re-save unmodified sub-materials.

Clusters

• UV Editor Refresh - The UV Editor now refreshes after enabling/disabling raytracing and antialiasing with a cluster configuration running.

• UI Fix - Fixed an error in the Cluster Manager interface.

Collaboration

• Object Placement and Place Tool - Object placement is synced with the Place tool for all participants in a collaboration session.

• Switching to Raytracing - Antialiasing works when switching to raytracing in a collaboration session.

CPU Raytracing

• Glass Refraction - The refraction for a single glass material atop a material with transparencies in layered material is now calculated correctly.

  2022.2 and before	2022.3 Fix

• Missing Caustics - When using Full Global Illumination or photon mapping, caustics for specular Substance materials are displayed.

  Missing Caustics	Fixed 2022.3

• Tinted Glass - The tint is preserved on a layered glass material.

  Material Editor Settings	2022.2 and before	2022.3 Fix

Decore

• Clones - Decoring no longer breaks clone structures.

• Parent Node - Parent node transformations are considered when decoring.

• Additional Vertices - When geometry is decored, additional vertices are removed, not added.

General

• FBX Export - X-Rite Measured material names are preserved during the export of FBX files, thereby also preserving material references.

• Nvidia Drivers - Installing Nvidia drivers on a Linux system doesn't crash VRED.

• Sticky Selection - Creating a light in the Light Editor, then clicking an empty area in the Scene Graph, deselects the current selection.

• List Measured Material Name - X-Rite Measured material names are preserved during the export of FBX files, thereby also preserving material references.

• Invisible Instances - When importing an Alias file, invisible instances are not imported when Import All surfaces is selected. They will only be included if Import Invisible Instances is enabled.

GPU Raytracing

• Backplates - Fixed backplate behind dark glass, so it no longer appears clipped.

• Background Color - The Render Settings background color is no longer seen on glass materials in GPU raytracing offline rendering.

  2022.2 and before	2022.3 Fix

• Photon Mapping - Photon mapping with Final Gathering appears as expected. There are no more issues with photon or irradiance mapping.

• Ring Pattern - When in Precomputed + IBL and Full Global Illumination, sharp glossy reflections with very low roughness no longer display a ring pattern.

• Shifted Reflections - Changing the Bump Intensity of a Substance material with a flat normal map no longer shifts the reflections.

• Disabling GPU Raytracing - Switching from GPU Raytracing to OpenGL(Off) works as expected.

• Texture-based Shadows - The crash when baking many lightmaps has been fixed. Now, calculating texture-based shadows when texture baking on the GPU works as expected.

• Glass and Decals - Layered materials with glass and decals render as expected.

  Issue	Fixed 2022.3

• Layered Materials - Layered Materials are rendered correctly when GPU raytraced.

Material Editor

• Preview Image - A material preview image is rendered when Show B Sides and Raytracing are enabled.

OpenGL

• Geometry Light Sources - Enabling Geometry Light Sources in OpenGL for scenes with many geometry light sources no longer leads to a crash.

Python

• .saveFile() - Added functionality to .saveFile() in `vrFileIOService.

• Function Update - Updated the Python v2 API to include functions that were missing.

  • vrdData Objects - vrdData objects in the VRED Web API now use the Python documentation getter/setter key names.

Raytracing

• Reflective Substance Materials - Reflective Substance materials are now traced in Precomputed + Reflection and Precomputed + Shadows modes, where roughness is < 0.01 on the surface.

• Missing Internal Reflections - When using subsurface scattering on plastic materials, all internal reflections are present. Now with this fix, you can get results similar to normal glass.

• Use a Light Source - Fixed the issue with disabling Use as Light Source in the Material Editor's Incandescence section with multi-selection.

  • Isolate View - Improved performance when using Isolate View with raytracing.

Rendering

• Shifted Pixels - Pixels are properly aligned for environment and skylight glossy reflections in all render modes.

• Environment Projection Fix - An environment with many bright lights, such as the Berlin_Plaza_Night example environment, now uses different light directions for Shadow Light sources, due to the shifted pixels fix.

  2022.2	2022.3

• Blurry DLSS - DLSS quality for both eyes in OpenGL stereo rendering is identical.

Smart References

• Smart references can now be sucessfully saved to the root folder of a drive.

Stream App

• Freeze - The Stream App is no longer frozen when loading a geometry-intensive file from VRED Pro.

Substances

• Normal Mapping - Substance materials with photon mapping using caustics display the correct normal maps when rendered.

• Diffuse Colors - When CPU raytracing, Substance diffuse colors appear as expected.

Variants and Variant Sets

• Old Render Queue Jobs - Variant Set exported XML files no longer contain references to old Render Queue jobs.

• Localized Versions - Variants from a .vpb (English) work correctly when imported into a localized (non-English) version of VRED.

VRED Core

• Adding a User - When starting VRED Core using -edit_preferences, a user can now be added to the Authentication section of the preferences.

• CSB files are successfully loaded into the VRED Core Windows version.

• OpenGL and 480p - For Linux VRED Core, images are now rendered in OpenGL when the resolution is set to 480p.

• Color Profiles - ICC profiles are now embedded with VRED Core and VRED Server Node.

• Secure Python - On VRED Core, when Secure Python is enabled, it works as expected.

Web Engine

• Icon Display - All rotated icons in the circular menu are visible and displayed correctly.

  Web Engine before 2022.3	Fixed issue in 2022.3

• "–enable-gpu-rasterization" - The environment variable parameter, "–enable-gpu-rasterization", was removed to fix the Qt 5.155 rendering of transformed SVG graphic issue. However, if you are experiencing lower Web Engine performance than expected, use QTWEBENGINE_CHROMIUM_FLAGS="--enable-gpu-rasterization --ignore-gpu-blocklist" to restore the previous version settings.

• Web Server Config Changes - Changes can be made to the Web Server configuration while running a real-time streaming session. However, for most changes, reloading the web page by pressing F5 or clicking reload in the browser is required.

Known Issues and Workarounds

• Differing CPU Raytracing results with the Glass shader between 2021 and 2022 - Surfaces using the Glass shader that were CPU rendered in VRED 2021 will look different when CPU rendered in VRED 2022. This is due to the Glass shader fix in version 2022.

• Cluster Failure - A cluster will fail to start, if the last node is localhost in the cluster list.

  

  Explanation: A pipeline and PCs at the beginning of the list need to reach PCs later in the list by the given Name or IP Address. If localhost is used, VRED tries to use the hostname of the master PC; however, PC 10.148.241.230 doesn't know GRED-P710 by name.

• Selection highlighting of individual surfaces in a shell is not yet implemented.

• Specular reflections of local lights are missing.

• New scene crash - If you click Yes when asked to interrupt the Python interpreter, after clicking New Scene, and no Python scripts are running, VRED crashes.

  Solution: Click No when asked to interrupt the Python interpreter.

• Denoiser can produce artefacts when rendering out non-premultiplied alpha renderpasses.

• Internet Explorer dependency - If installing VRED 2020 on a machine running Internet Explorer, Internet Explorer 10 is needed to display the Let's get started screen.

  A workaround for this is to create a deployment installer. When creating deployment installer images, VRED starts up fine for all license types. In the VRED user control popup menu,

  • Sign In works
  • Sign Out And Quit (user license) won't work
  • Manage License won't work
  • Explore Purchase Options sort of works, but the web page looks strange due to the older version of Internet Explorer
