--- title: "7.20.08" canonical: "https://documentation.chaos.com/space/VMAX/397508614/7.20.08" format: markdown --- ## **V-Ray 7, update 2, hotfix 3** *Official release* **Date **- Dec 16, 2025 > Macro (ui-button) ### **New Features** --- **V-Ray GPU** - Support for mapping options of the VRayEnvironmentFog ### **Modified Features** --- **V-Ray** - Deduplicate tyActor instances to reduce the exported .vrscene file size - Fixed problem with mouse wheel scrolling for the Object Hierarchy meshproxy dialog - Support for USD 0.13.00 - Disabling a parent layer in the Exclude/Include layers menu should also disable all its sublayers - V-Ray Cosmos browser has to be closed on changing to non-V-Ray renderer - Gray out the Save denoiser extra data checkbox in the file save dialog on disabled memory FB - Allow Live Link 2 with Vantage - VRayBitmap's color space options should affect the Bitmap preview (from View Image) - Improved UI layout for Save V-Ray image file window - Option to disable the VRayVolumeGrid's Icon Text - Objects act like they are selected with pressed Ctrl button even after Ctrl button was released in VRayLister - Support for tyBitmap export and V-Ray Standalone CPU rendering - Extend the exclude/include support for VRay IES light - Consider subdivision quality settings when converting Corona displacement to VRayDisplacementMod **V-Ray GPU** - Render direct illumination from the Moon in V-Ray Night sky ### **Bug Fixes** --- **V-Ray** - MultiMatte's include/exclude lists are not considered in IPR - tyFlow mesh only visible on first animation frame when using camera motion blur and DR - Object visibility does not work on tyFlow objects - Artifacts around stars with Bloom and Glare in lens Effects - Copied meshes with modified normals export and render differently in V-Ray Standalone - 3dsMax crash when updating Xref scene during IPR GPU DR session - Copying V-Ray Gaussian Splat creates a broken copy - Incorrect normals and lighting of tyCache particles in V-Ray Standalone - DR2 | Crash when stopping the render directly after the server begins to render - DR2 | The VRayClipper object itself is rendered when using "Use local host" - Crash with any Anima Car + 4D Walking people when using IPR on frames above 0 - Wrong Zdepth element when opacity mapped objects are intersecting the Gaussian Splat bounding box - Incorrect behavior of VRayProxy dockable rollouts in create mode - VRayBitmap's viewport preview does not update properly when previewing an animation - Crash when trying to render with DR2 and a LightMix RE is present in the scene - Crash with DR2 builds and V-Ray Profiler set on a location different than default - The help button for GPU Color management in Render setup opens CPU Color management docs page - USD-Promoted objects are overlapping with the initial geometry when rendered with Standalone - Crash when render tyFlowt ySplines and tySplinesMesher geometry - VRayPhysicalCamera's focal length is rendered wrong with USD 0.11.0 and above - Fireflies when using Secondary ray bias with textured lights on vrscene export - Crash on undo operation with VRayIES, VRaySun light, VRayFur, and others when changing parameters - VRayCryptomatte mask doesn't work with Xref object and MultiSubObject materials - Proxy visibility does not work with Distributed Rendering and transfer missing assets - GPU motion blur does not work with tyFlow and animated mesh - tyActor animation is not exported as sequence - Extreme slowdown between frames when rendering tyCache with instanced geometry in it - Wrong parameter field types in VRayDirt and VRayEdgesTex causing wrong results with import into a scene with different system units - Wrong Inverse Gamma when converting non-linear images through the V-Ray Converter and 3ds Max Color Management set to OCIO default - Mapping options of VRayEnvironmentFog shouldn't be greyed out when switching to V-Ray GPU - V-Ray Lister 'Multiplier' parameter is not syncing on multiple light selections when changing the 'Units' parameter - Flickering with very small VRaySphereLight(s) - Black circle in Night Sky when the VRaySky is positioned in dome VRayLight with locked texture rotation to icon - The moon draws on top of everything with Aerial Perspective active - Incorrect color of the VRaySky viewport preview - Contrail clouds get shifted by cloud start height **V-Ray GPU** - Memory leak with VRaySun and night sky - CUDA performance regression with specific scene compared to V-Ray 6 **VFB** - VFB Exposure Layer masks are affected by other correction layers above - Exposure mask remains active if focus is lost while holding hotkey **Standalone tools** - Vdenoise does not work when the input image has VRayEnhancerData RE
