(*) "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;
(*) Banding with very small spherical VRayLights;
(*) SSS with VRayMtl did not work properly with intersecting refractive objects;
(*) Problems with dome light and matte/shadow materials with GI on;
(*) VRayBlendMtl in additive mode produced incorrect alpha channel;
(*) VRayHDRI did not free is memory with the freeSceneBitmaps MaxScript command;
(*) Crash when rendering disconnected Particle Flow events;
(*) In 3dsmax 9, clearing a texture in VRayMtl could cause a crash, if the texture is visible in the viewport;
(*) In 64-bit 3dsmax, the Dynamic raycaster memory spinner was still limited to 4096 MB;
(*) In some cases VRayFur did not render properly;
(*) Wrong mapping coordinates for VRayFur when motion blur was enabled;
(*) Incorrect velocity G-Buffer channel due to camera movement for scaled cameras;
(*) Distortion map for VRayToon had no effect;
(*) Light cache prefiltering ignored GI surface IDs;
(*) VRayLight’s appeared in reflections for objects excluded from the lights;
(*) Light cache files saved on 32-bit machines did not load properly on 64-bit machines and vice-versa;
