  • Fixed an issue where loading a scene that contained NVIDIA Iray canvases and named node lists (masks) would result in the node lists being created but would not restore associations between a canvas and a named list
  • Double-click on NVIDIA Iray canvas entries (to edit the name of the canvas) are now limited to the name column
  • Extended support for the NVIDIA Iray “Toon” canvas
    • Added an “Outline Normal Difference (Bias)” property

    • When set to “Orientation” (default), “Bone” avatars are drawn axis-aligned according to the orientation of the bone itself
      • Clicking the bone avatar causes the bone itself to become selected
    • When set to “Hierarchy”, “Bone” avatars are drawn between the origin of the bone and the origin of its parent
      • “Joint” avatars are drawn around the origin of the bone
      • Clicking the joint avatar causes the bone itself to become selected
      • Clicking the bone avatar causes the parent bone to become selected
      • This mode is intended to be visually/behaviorally familiar to users of other 3D applications
  • Made improvements to FBX Importer
    • Figures that do not define face set/group selection maps now configure bone drawing/behaviors to be familiar to users of other 3D applications

    • Fixed an issue with being able to click on bone/joint avatars of objects that do not define a node/geometry selection map if the avatar being clicked is completely contained within geometry
      • Non-static objects that lack selection map definitions set the “Bone Draw Mode” property to “Hierarchy”
    • A DzBoolProperty named “CTRLDisableAutoFit” is now used to prevent the AutoFit dialog from being displayed while establishing follow target/follower relationships
      • The property label is “Disable AutoFit”
      • The property is accessed from the General > Misc property group on the Parameters pane
      • The property is created on the skeleton node of non-static objects that do not define a rig of their own
        • Followers that were merged during use of FBX Exporter (and so lost their independent rig/binding)
        • Geometries that originate from another source, bound to the same rig as a primary geometry

Private Build Channel

This channel is similar to the Public Build channel, except that it is limited to a select group of individuals that serve as the “front line” or the “canary in a coal mine” for a time before the build is promoted to a less restricted channel. This channel is more likely to see an ALPHA build than the Public Build channel is.
