  • 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

  • The Fire Color and Intensity curves should act as a whole when fitted

  • V-Ray RT won't render smoke shaded by Smoke channel

  • Volumetric Geometry mode creates holes in Alpha at geometry intersection when Jittering is enabled

  • When editing diagram handle coordinates, Smooth Bezier handles stop working properly

  • Wrong velocity scaling with imported volumetric simulation from Houdini

  • Node transformation is applied only to the vertex channel but not to the normals channel
