RTX Renderer Release Notes#

Current Release#

107.2#

Release Highlights#

In this release, camera simulation capabilities have been extended to further support accurately simulating real-world camera lenses by leveraging OpenCV’s robust Pinhole and Fisheye camera models. See the Camera Fisheye Lens section for more details.

Also, a Data Window concept was added that exposes new render settings, based on USD specifications, to control the rendering data window dimensions in normalized device coordinates (NDC). This feature enables users to adjust the data window dimensions independently from the display window, such as for cropping or overscan. See the View section for more details.

Added#

  • RTX: Added support for OpenCV Pinhole and Fisheye models to cameras.

  • RTX: Added Data Window controls, which exposes settings to enable cropping or overscan of the data window.

  • RTX Interactive: Added subsurface scattering AOV storing diffuse transmission direct and indirect light path. With this AOV, it is now possible to sum the AOVs to match the beauty results.

Improved#

  • RTX: When swapping materials, the previous material is rendered until the incoming one is loaded to avoid rendering an intermediary undefined appearance. This behavior is applied only if Fabric Scene Delegate is enabled.

  • RTX: Improved clarity for warning messages produced by progressive scene loading.

  • RTX Real-Time: ‘Translucency as Opacity’ now has the same behavior for both RTX Real-Time and RTX Interactive modes, and now works without having to enable ‘Fractional Opacity’.

  • RTX Real-Time 2.0: Various quality improvements to improve parity with RTX Interactive.

  • RTX Interactive: Denoising quality with Optix Denoiser has been improved for materials which have subsurface scattering.

  • RTX Interactive: Temporal denoising quality with Optix Denoiser has been improved.

Fixed#

  • RTX: Fixed a crash which could occur when switching between RTX Renderer and Iray.

  • RTX: Fixed an issue with Compositing where the background color could still be visible through the outline of the objects even if ‘blackBackgroundInComposite’ was enabled.

  • RTX: Fixed an issued which prevented rendering newly added primvars to points and curves.

  • RTX Real-Time: Fixed some cases where blurriness would occur behind glass.

All Releases#

Known issues#

  • RTX Interactive: UI responsiveness can lag when rendering complex volumes.
