Rendering#

Fixed#

  • RTX - MDL shaders fail to load when the asset folder name starts with Z followed by an underscore and hex-like characters (e.g. ZA_5449000177551), as the name is incorrectly interpreted as an MDL module name mangling pattern by the EntityResolver. [OMPE-83668]

  • RTX - Opening a saved USD file that contains point cloud streaming prims causes errors when not connected to IVION, and reconnecting to IVION after opening does not reload the point cloud streaming data. [OMPE-81393]

  • RTX - Composite background after tone mapping setting incorrectly applies a background composite when background override is set to None, causing an unexpected cyan background when the texture path is invalid, and forces the alpha channel to fully opaque during Movie Capture even when Save Alpha is enabled. [OMPE-80993]
