V-Ray 1.5 SP5 is the next release of the V-Ray rendering engine for 3ds Max. In addition to several new features and bug fixes, this service pack provides compatibility with 3ds Max 2011 and 3ds Max Design 2011.

New features:
# Added VRaySamplerInfoTex texture and VRaySamplerInfo render element
# Added VRayObjectSelect render element which allows to extract objects with specific IDs into a separate element

Modified features:
# Added an option to the VRayPhysicalCamera to perform image distortion based on a texture map
# Allow the user to specify texture bounds for 3d displacement
# Added displacement slot to VRayFastSSS2 material
# Added "prepass id" parameter to VRayFastSSS2 material so that multiple materials can share the same illumination map
# Added displacement slot to VRayLightMtl material
# The color parameter of VRayIES lights is now animatable
# The min/max z-depth values for the VRayZDepth render element are now animatable
# Support for reflection occlusion in VRayDirt
# Support for environment sampling in VRayDirt
# Support for Particle Flow vertex color mapping and particle visibility
# Support for the "Use transparent shadows" option with Arch&Design materials
# The clipping planes for the VRayPhysicalCamera are now displayed in the viewport
# Added an option "show cone" to the VRayPhysicalCamera to control the display of the camera in the viewports
# Ability to save and load color correction curves for the VFB in Adobe® PhotoShop® .acv format
# Support for pixel aspect ratio display in the V-Ray VFB
# Support for anaglyph stereo preview in the V-Ray VFB
# Support for LUT color correction in the V-Ray VFB from .cube files
# Ability to display the value of the corrected colors in the V-Ray VFB pixel info dialog
# The "Dynamic memory limit" parameter can be set to zero to remove any limit

Bug fixes:
# Motion blur for Hair&Fur in "mr prim" mode does not match the "buffer" mode
# Occasional random crashes in 3ds Max 2010 due to progress bar updates
# Fixed invalid smoothed normals causing issues with displacement
# Fixed AA artifacts with thin bright lines when using Adaptive DMC image sampler
# Stuck buckets with perfectly transparent surfaces and GI
# Incorrect vignetting for VRayPhysicalCamera when using horizontal/vertical offset
# setVRaySilentMode() should disable the dialog for overwriting raw .vrimg files
# Missing reflections in VRayFastSSS2 when it is a coat material inside a VRayBlendMtl
# Incorrect bump mapping for GI when using time-interpolated irradiance maps
# Fixed artifacts with VRayFastSSS2 when one of the scatter color components is zero
# Fixed incorrect normal map with VRayNormalMap on VRayProxy objects
# Fixed crash with animated irradiance maps and objects with zero scale
# The color of VRayIES lights was not animatable
# VRayIES lights did not produce photon-mapped caustics
# Fixed invalid normals with VRayEdgesTex in the bump slot
