scene lights if a Rectangle, Sphere, Spot or Mesh light is present in the scene IPR IPR is not updated for volumes when the Renderer's Sampler type is set to "Bucket" Hooking/unhooking nodes under a File SOP used for loading VDBs (e.g. Transform SOP) did not update IPR Changing the visibility flag on a piece of geometry would occasionally cause the entire geometry to disappear Creating a node inside a V-Ray Material Builder VOP used to restart the IPR even if that node is not a part of the shading network attached to the rendered geometry Adding or removing an input connection to a VOP node would occasionally fail to update IPR Pressing the "X" button on the VFB to close the window would not stop the IPR When Motion Blur is enabled, objects with velocity blur used to have wrong

properties are not applied to the Geometry node Can not start IPR if a Render View panel is not present in the Houdini UI Disabling the visibility of Geometry node holding a VRScene SOP while IPR is running causes a crash if there is a material override assigned to it Objects imported into a sub-network disappear when changing settings on their assigned materials Changing the visibility of a Geometry node during an IPR session has no effect IPR used to discard a light if the Intensity parameter is animated and it reaches zero during the animation Changing Volume Grid Shader parameters during IPR would occasionally cause incorrect scaling of the volume Removing the file path from a Light's Emission Color or Shadow Color texture parameter does not update IPR Crash when starting a VFB IPR session with a V-Ray Renderer ROP inside an HDA The Ignore flag of VOP nodes does not update IPR when a material is assigned through a Material Output VOP Empty Render View IPR and Viewport IPR when both "Use Denoiser" and "Use Render Elements" (with a RE:Denoiser) is enabled on the V-Ray Renderer ROP Crash with CUDA CPU IPR and BRDF Stochastic Flakes because object level scale is ignored by the BRDF CUDA IPR errors and crash when changing Volume Grid shader options while IPR is running Start Offset option of the V-Ray Proxy is not updated in IPR Connecting a Displacement VOP to a

output when rendering in Volumetric Mode Added missing "Color Mapping", "Consider for AA" and "Denoise" options to the Light Select render element The "Denoise" option on Color Channel render elements had no effect No Anti-Aliasing for Cryptomatte element in Material mode because of missing face_mtlIDs parameter on GeomStaticMesh Presence of "Reflection Alpha" element causes wrong Reflection output Light Select output for volumetric effects was wrong due to a missing parameter output Instancing Material assignments are lost for instances using @instance or @instancepath when Rayserver Instancer is enabled Fixed a difference in Motion Blur when using the "v" attribute if Rayserver Instancer is enabled Wrong fields loaded for rendering of fire and smoke in specific cases with volume instancing Iterating over a large number of instances with a Post-Translate script causes a crash Fixed wrong export for instanced volumes when using 'unexpandedfilename' intrinsic attribute Mesh Material

Output Path of a Renderer ROP when the variable starts with "F", e.g. "${FNAME}" Specifying an object which is a child of a sub-network in the Renderer's Force Objects list forces the entire parent sub-network An object which is a child of a sub-network specified in the Renderer's Exclude Objects list is still rendered A Candidate Object is rendered even when the node Display flag is disabled if

produces wrong results COP image used as a texture for the Physical Camera's Bitmap Aperture produces wrong results Fixed wrong gamma export for COPs images Lights All lights are exported regardless for the Geometry node's Render -> Shading -> Reflection/Refraction Mask parameters making disabling reflections or refractions of specific lights for the given object impossible Light linking for
