Added#

  • RTX: The Render Settings’s Debug View has been renamed to View and is now listed under RTX Common, rather than the Debug section. It includes the newly-added Illuminance and Luminance AOV views and their respective view settings.

  • RTX Interactive: Luminance and Illuminance AOVs have been added, along with viewing and picking settings in the render settings’ Common View section.

  • RTX Interactive: Light Linking is now supported even if Fabric Scene Delegate is enabled.

Improved#

  • RTX: The BasisCurves texcoord loading code has been augmented to load and if necessary interpolate constant, uniform, and vertex primvars. Varying primvars are not currently supported.

  • RTX: Unsupported Debug Views have been removed from the Views UI.

  • RTX: Improved performance of animation/editing of instance-interpolation primvars (point instancer).

  • RTX: Meshes with subdivision refinement are now cached, speeding up scene load time.

  • RTX Interactive: If Denoise AOVs is enabled, the Alpha channel will now also be denoised.

Fixed#

  • RTX Real-Time: Fixed an issue where for some complex materials, fractional opacity would appear as opaque.

  • RTX Interactive: Fixed a crash which could occur when switching to this render mode with multiple GPUs enabled.

Known issues#

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