  • EXR textures are always loaded as 32-bit floating point

  • Low precision of 32-bit tiled EXR

  • Slow rendering of subdivision surfaces in certain cases

  • Difference in interpretation of alpha when using files without alpha channel

  • Connecting an image into RectLight's alpha is not working

  • Moving a layered texture slot connected to VRayPluginNodeTex crashed Maya

  • Maya crashed if a scene was loaded while V-Ray was still rendering

  • Fixed slower rendering when using Maya's Render View compared to using the VFB

  • Progressive sampling + DR + "Don't render final image" did not finish rendering

  • V-Ray materials did not respect the display/render layers for the lights in Viewport 2.0

  • When "Use irradiance map option" of a diffuse material was turned off, Maya crashes

  • V-Ray crashed when the "Flake map size" option for the FlakesMtl or CarPaintMtl was too large

  • Fixed various issues with VRayMtl on back-facing surfaces

  • VRayCarPaintMtl and VRayFlakesMtl with flake glossiness 1.0 resulted in invalid colors

  • VRayUserColor didn't work with VRayLightMesh and VRayLightMtl material with "direct illumination" enabled

  • Exporter's memory was not deallocated with hair and "Use camera path"

  • "Use camera path" produced wrong result when used with "Camera and Aim" after beta 3

  • The dome camera didn't work with FOV bigger then 165 degrees

  • Fixed crash with spherical harmonics GI

  • Fixed wrong rendering with multiple VRaySoftbox textures on the same scene

  • Fixed crash with renderable curves

  • Fixed incorrect filter file names for V-Ray nodes in the various dialog boxes
