Build 1.50.RC5
==============================

New features:
(*) New render elements: VRayMatteShadow, VRayTotalLighting, VRayRawTotalLighting;
(*) Added exporter script to the .vrscene file format supported by the standalone version of V-Ray;
(*) Animation modes for the irradiance map (added two new modes "Animation (prepass)" and "Animation (rendering)" along with a paramter to control the blend between frames;

Modified features:
(*) Increased rendering speed for some types of scenes;
(*) Updated WIBU-key drivers for 32- and 64-bit Windows* (including Windows* Vista*) are included with the installation;
(*) VRaySun is now compatible with the 3dsmax Daylight system and can be selected as a sun type;
(*) VRayDisplacementMod now supports high-dynamic range textures for displacement in "2d landscape" mode;
(*) VRayPhysicalCamera supports horizon line in the viewports, clipping and environment near and far ranges;
(*) Distributed rendering can now be started as a BackBurner job;
(*) Added an option to exclude specific objects from overriding their material from the Global Switches rollout;
(*) VRayColor texture has an option to apply gamma correction to the displayed color in the UI;
(*) "Don't affect colors" option for color mapping; useful if you only need the sampling adaptation to be performed;
(*) "Cutoff" threshold parameter for VRayLight's allows to reduce render times in scenes with many weak lights;
(*) "Envrionment priority" option added to VRayMtl to control environment override behaviour between different materials;
(*) Options for directly controlling the render mode (region, crop etc) of the V-Ray VFB;
(*) "No GI on other mattes" and "GI surface ID" parameters added to VRayMtlWrapper;
(*) Matte objects with the "Shadows" option checked will now generate VRayRawLighting, VRayRawShadow and VRayMatteShadow elements;
(*) If "Check for missing files" option is checked, DR will now fail on the render slaves if some maps cannot be found, instead or rendering wrong buckets;
(*) If there are several VRaySun nodes in the scene, VRaySky will now pick the first one that is enabled (rather than the first one at all);
(*) V-Ray will now force multithreading when 3dsmax is in slave mode, regardless of the 3dsmax multithreading option;
(*) When rendering to texture (RTT) the 3dsmax VFB is now always generated, regardless of whether the V-Ray VFB is on or off;
(*) The irradiance map viewer will print out the progress of merging irradiance maps;
(*) The autosave file names for irradiance/light cache/photon/caustics maps are now updated at each frame, rather than only at the render start;
(*) The irradiance/light cache/photon/caustics maps are auto-saved as soon as they are computed, rather than at the end of the frame/rendering;
(*) The "Save maps per frame" option has been removed from the GI rollout;
(*) VRayProxy will now re-link the .vrmesh file at each frame, rather than only at the render start;
(*) V-Ray will write a tiled OpenEXR file directly to disk, similar to a raw .vrimg file, if the raw file name ends in ".exr";
(*) Added a new "hybrid" SSS model in VRayMtl;
(*) Added exclude list for material override in the Global Switches rollout;
(*) The uninstaller will unregister any V-Ray services as well(DR spawner, license server etc.);
(*) Added "Affect alpha" option to VRaySphereFade;
(*) VRayLights now produce accurate motion blur when animated;
(*) VRayFur can now generate motion blur with more than 2 geometry samples;
(*) Global option to work in the system lighting units of 3dsmax for consistent results with 3dsmax photometric lights;
(*) VRayLights produced wrong intensity with photometric units;
(*) VRaySun/VRaySky had wrong photometric intensity; they now have a "legacy model" option to use the old model, which is turned on automatically for older files;
(*) VRayPhysicalCamera ISO parameter produced wrong exposure; it now has a "legacy model" option to use the old model, which is turned on automatically for older files;
(*) VRayProxy objects now produce motion blur when the proxy transformation is animated;
(*) VRayProxy objects now generate velocity information for image motion blur when their transformation is animated;
(*) Re-worked VRayFastSSS material to use the irradiance map interpolation mechanism for faster and smoother results;
(*) Added an "Affect reflections" option to VRayLight's to control reflection visibility separately from speculars;

Known issues:
(*) When rendering a 3dsmax Raytrace material applied on VRayProxy objects, V-Ray will crash;
(*) When rendering a high-resolution image with the "Hilbert" region sequence, V-Ray may crash;

Bug fixes:
(*) "Affect shadows" and "Affect alpha" options did not work for VRayMtls inside a Multi/subobject material (RC3 bug);
(*) Moving VRayPhysicalCamera caused spurious MacroRecorder events about the target distance changing;
(*) Problems with 2D displacement (RC3 bug);
(*) Automatically created VRaySky did not have a name;
(*) Horizontal scrolling problems with the V-Ray messages window;
(*) VRayOverrideMtl could cause 3dsmax to crash;
(*) Multi/subobject material inside a VRayBlendMtl etc. did not render;
(*) 64-bit V-Ray could fall into an infinite cycle when rendering 2d displacement;
(*) Some rare raycaster precision errors were fixed;
(*) Starting/finishing rendering could be extremely slow in 3dsmax R9;
(*) VRayHDRI always took at least 10 MB of memory, regardless of actual image size (RC3 bug);
(*) Incorrect irradiance map density and texture sharpness when using camera clipping planes;
(*) Missing files (textures/VRayProxies etc) were not always detected correctly;
(*) Distributed rendering between mixed 32/64-bit V-Ray versions did not work properly;
(*) Standard materials with transparency did not render properly (RC3 bug);
(*) No motion blur for ParticleFlow on 64-bit 3dsmax;
(*) Color corrections from the V-Ray VFB were applied to the alpha channel when splitting the render channels to files;
(*) Crash with the "Show map in viewport" option for VRayMtl when using Direct3D (RC3 bug);
(*) Textures with mapping channels greater than 1 are now correctly shown in the Material Editor;
(*) The "Global light level" options from the Environment dialog now affect the color of VRayLights and standard 3dsmax lights;
(*) VRayBlendMtl did not list the blend textures as sub-anims;
(*) If "Render to raw image file" option for the V-Ray VFB was ON, but the file name is empty, V-Ray would freeze while rendering;
(*) The parameters of VRayMtlWrapper did not have proper names in Track View;
(*) If the primary GI engine was light cache or photon map but GI is turned off, standard materials would render black;
(*) VRayMtl materials with low glossiness inside a VRayBlendMtl could produce polygonal artifacts on shadow/light boundaries;
(*) The pixel aspect ratio from the Render Scene dialog was ignored when rendering with DR to the 3dsmax VFB;
(*) A low-dynamic range 3dsmax frame buffer was used even when saving to a high-dynamic range file format (.exr, .hdr etc);
(*) Problems when rendering animations in DR mode with light cache as both primary and secondary engine;
(*) Small rectangle area lights could produce artifacts for points lying close to the light plane;
(*) Somewhat better memory management for proxies and dynamic meshes;
(*) Crashes with VRayFur on animated objects when using motion blur;
(*) Incorrect environment color with several VRayLights in "dome" mode;
(*) "Crop" render mode with the V-Ray VFB did not work for animations;
(*) Sporadic crashes when using the "Camera Map Per Pixel" texture inside V-Ray materials (VRayMtl, VRayLightMtl etc);
(*) VRayBmpFilter did not always display its bitmap texture successfully;
(*) VRayBmpFilter could produce invalid colors;
(*) Photon mapping could produce wrong GI on transparent surfaces;
(*) Crashes with interpolated glossy reflections/refractions if there is only 1 sample in the interpolation map;
(*) Irradiance map produced incorrect results when used with VRayLight in "Light portal" mode;
(*) Faceting on low-poly geometry when using anisotropic reflections with UV-channel mapping;
(*) Incorrect sampling with gamma color correction when some of the pixel RGB components is zero;
(*) In 3dsmax 9, VRayMtlWrapper, VRay2SidedMtl, VRayOverrideMtl could crash when reset from the Material Editor;
(*) Some V-Ray materials (e.g. VRayMtl) did not reset when the "Reset" button from the Material Editor was used;
(*) The contents of the V-Ray VFB was not cleared regardless of the "Previous render" option in the System rollout;
(*) V-Ray sun could produce brighter highlights than is correct when its size multiplier is much greater than 1.0;
