Build 1.50.SP3 official (1 March 2009)
(cumulative changelog since build 1.50.SP2)
===================
New features:

VRayFastSSS2 material for simulating accurate sub-surface scattering;

VRayEnvironmentFog atmospheric effect;

VRayLightMtl has options to generate direct light;

VRayLight has a "Mesh" mode to allow geometric lights;

Support for the 3ds Max Arch&Design material (most basic options are supported);

Support for vector displacement in VRayDisplacementMod;

Global ambient occlusion for all supported GI engines (irradiance map, light cache, photon map);

Added VRayVectorDisplBake material and VRayNormalMap textures to help produce and use textures for vector displacement;

Modified features:

V-Ray requires a SSE2-capable processor even for 32-bit versions;

Reduced flickering for time-interpolated irradiance maps;

Support for volumetric irradiance maps, light cache and photon maps;

VRayFur uses volumetric irradiance maps/light cache to speed up rendering;

VRaySun is never visible to GI rays (removes spots from the sun in the irradiance map);

The "Default lights" option now has three possible values - "off", "on" and "off with GI";

Added MaxScript access to the include/exclude lists of VRayLights (including VRaySun and VRayIES) through the "excludeList", "includeList" and "inclExclType" MaxScript properties;

Camera information (transformation, FOV etc) is written to .vrimg and OpenEXR files when using the "Raw image file" option of the V-Ray VFB; vrimg2exr also translates this information;

Support for region rendering directly in the V-Ray VFB;

The "Affect alpha" option of VRayMtl has been replaced with "Affect channels" option and allows propagation of all render elements, not only the alpha channel;

The alpha channel is correct for glossy refractions that have the "Affect channels" option set to "Color+alpha" or "All channels";

The "Use irradiance map" option in VRayMtl materials now concerns the light cache too;

VRayDirt texture has include/exclude options for objects that should affect and should be affected by the dirt texture;

The default Distribution parameter of VRayDirt is set to 1.0 (corresponds to using the dirt for ambient occlusion);

Camera overrides (e.g. spherical, box etc), work when rendering through a VRayPhysicalCamera, picking the exposure from it;

Added another preview option to VRayProxy (preview from file as faces instead of edges);

Added animation export parameters to the meshExport() MaxScript function;

Option to specify the maximum number of faces in the preview of exported .vrmesh files;

VRayProxy has the possibility to extract the geometry from the .vrmesh file as a 3ds Max mesh;

When exporing a .vrmesh file, V-Ray will put up a warning if the file already exists;

In VRayProxy objects, a sequence of '#' characters in the file name is replaced with the current frame number;

Added "Horizontal offset" and "Vertical offset" parameters to VRayPhysicalCamera;

Added "Horizontal shift" parameter to the physical camera;

The MultiMatte render element has an "affect matte objects";

The MultiMatte render element works with transparent objects;

The VRayZDepth render element works with transparent objects (when "Enable filtering" is ON);

The VRayZDepth render element has filtering enabled by default;

Added "Affect matte objects" option to VRayExtraTex render element;

VRayExtraTex render element works with transparent objects;

Render element names reverted to VRay* (without underscore);

Option to restart render slaves for DR after the rendering completes;

The distributed rendering settings window can be resized now;

Check/uncheck all selected servers in DR settings dialog;

Support for the incremental modes of the irradiance map in distributed rendering;

V-Ray will transfer the 3ds Max gamma settings for DR rendering;

Some small changes in the network code to see if DR is more reliable;
