VRaySamplerInfo

  • Multi-sampled motion blur produces artifacts on animated proxies

VRaySkinMtl

  • Doesn't work with the Vexus material from John Martini

VRaySky

  • Deleted VRaySun still appears in the VRaySky

VRayStochasticFlakesMtl

  • Does not appear in the Material Editor when V-Ray RT/GPU is selected as render engine

VRayToon

  • Black color in Width map produces artifacts in the RGB and render elements

VRayTriplanarTex

  • Crash when connected to bump slot through VRayNormalMap

  • Invalid bump normals warnings when source texture returns zero UVW coordinates

  • Normal maps are not rotated properly

  • It is possible to open the right click menu when moving a point in the diagrams or gradients

  • Interface lag when looking at a missing frame from a very long cache sequence

  • Motion blur for volumetrics does not take into account Interval center

  • Per-axis zoom in the shading diagrams does not respect the cursor position

  • Rendering with motion blur and duration=0 will preprocess forever

  • Scene saved with the old curves in Simple Smoke mode always has Inactive transparency diagram

  • Scrubbing the timeline with animated Direct Cache index leads to 3dS Max crash
