109.0.4#

Changes since 109.0.2

Improved#

  • Point cloud Level-of-Detail (LoD) performance improved by fetching only incremental changes each frame rather than reloading the full state. [OMPE-53379]

  • Updated DLSS Ray Reconstruction with support for per-tile dimensions, improving compatibility with tile-based rendering workflows and reducing noise along screen borders during motion. [OMPE-78022]

  • Improved warning message for basis curves without width data, identifying the affected curve and noting that a default width of 1.0 scene units will be used. [OMPE-57555]

Fixed#

  • Intermittent GPU crash on Windows during matte object fade-out caused by unguarded texture coordinate access. [OMPE-50098]

  • ECO mode could break animation playback on instanced root objects when renderer instancing was enabled. [OMPE-75123]

  • Animated and skeletal meshes could disappear or clash detection bake visualization could render incorrectly when visibility changed, due to repeated re-requesting of streamed geometry. [OMPE-73074] [OMPE-70548]

  • Instanced prims could render without their expected base color due to incorrect material key assignment. [OMPE-72538]

  • Application crashed when running NuRec/NRE/NeRF tiled rendering on Blackwell-based systems. [OMPE-70517]

  • Scenes appeared incorrectly dim due to path weighting being applied twice when blending fog contributions. [OMPE-74364]

  • AOV rendering produced sparkle and shimmer artifacts when using RTX Real-Time 2.0 due to incorrect temporal accumulation. [OMPE-72955]

  • Fog lighting produced “firefly” artifacts causing objects to appear overly bright in RTX Interactive mode when OptiX denoising was enabled. [OMPE-73080]

  • Debug View crashed or triggered asserts when selecting Stable ID or Semantic ID visualization modes, including on A40 GPUs. [OMPE-69718]

  • Enabling renderer instancing could cause instanced objects to disappear or clash detection results to be missing or inconsistent after reopening a scene. [OMPE-72486]

  • Ray tracing could hang or crash when a camera’s near and far clipping planes were inverted or set to extreme values. [OMPE-40037]

  • Tiled NuRec volume rendering crashed due to incorrect instance-slot handling during compositing. [OMPE-70581]

  • Application crashed during playback or scrubbing of timesampled deforming meshes with per-vertex animated normals. [OMPE-76830]

  • Enabling Simple Fog caused dome light contributions to be incorrectly weighted in random-walk paths, and some scenes could render materials as gray. [OMPE-79286] [OMPE-78014]

  • Viewport flickered when running with multiple Hydra render engines and the present thread enabled. [OMPE-54307]

  • Texture cache creation failed on Windows for user profiles containing non-ASCII characters. [OMPE-78387]

  • Renderer present-thread synchronization could crash during shutdown or frame presentation on both Windows and Linux. [OMPE-81389] [OMPE-75384] [OMPE-75492]

  • Motion vector calculations could produce NaN values, causing ghosting and smearing when rendering streamed point clouds in RTX Real-Time 2.0. [OMPE-71837]

  • OpenColorIO tonemapping shader compilation failed with certain OCIO configs such as PixelManager. [OMPE-68427]

  • NVIDIA IndeX did not re-run the USD importer after changes to importer settings, requiring a stage reload to apply updated settings. [OMPE-46941]

  • Firefly filtering parameters could be clamped to incorrect values, causing render settings to be written in a way that could not be read back. [OMPE-80094]

Security#

  • Updated OpenColorIO to version 2.5.0 to address a security vulnerability in the bundled XZ Utils dependency. [OMPE-42868]

  • Updated NVIDIA IndeX libraries to version 387500.3473, including an OpenSSL upgrade to address CVE-2025-15467. [OMPE-80085]
