Release Highlights#

In this release:

BasisCurves now support constant, uniform, and vertex primvars, which can enable workflows such as those requiring colored curves.
RTX Interactive’s Light Linking feature is now supported even with Fabric Scene Delegate enabled.
The Section Plane feature now supports multiple planes. See the Section Plane section for more details.
Luminance and Illuminance AOVs are now available with RTX Interactive. See the RTX - Interactive (Path-Tracing) Views section for more details.

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.

RTX: The Section Plane feature now supports multiple planes by specifying four floats per plane for its float array.
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.

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.
