  • attribute paint value control is now a float slider vs. color picker.
  • fixed a bug which caused non evaluated nodes to crash Maya when displayed as a heat map in the graph editor.
  • initial build for Maya 2019, only support for Arnold/MtoA as the other rendering engines don’t have Maya 2019 builds yet.

3.1.6

Released: 23/01/19

Dependencies: MtoA 3.1.0.0, Arnold 5.2.0.0, VRay 4.04, Renderman 22.3, 3Delight 12.0.113, Redshift 2.6.27, Clarisse 3.6 SP4

  • fixed a bug introduced into the Attribute node that would cause Yeti to crash.

3.1.5

Released: 18/01/19

Dependencies: MtoA 3.1.0.0, Arnold 5.2.0.0, VRay 4.04, Renderman 22.3, 3Delight 12.0.113, Redshift 2.6.27, Clarisse 3.6 SP4

  • corrected By Length sampling in Guide node to improve shape matching.
  • Attribute node can now sample Vector attributes from Groom/Guides.
  • fixed a regression issue that caused bald areas in 3.1.4.

3.1.4

Released: 14/01/19

Dependencies: MtoA 3.1.0.0, Arnold 5.2.0.0, VRay 4.04, Renderman 22.3, 3Delight 12.0.113, Redshift 2.6.27, Clarisse 3.6 SP4

  • ensured generated Braids have correct motion data, when missing a few nodes would crash on evaluation.
  • fixed Braid fibre id generation, this fixes a bug where some nodes only affecting the percentage of fibres wouldn’t correctly evaluate.
  • fixed a bug that was causing Yeti to crash when Scattering points onto instanced Mesh objects.
  • fixed a bug in cubic interpolation of strand systems that could cause noise when evaluating the end of a curve.
  • fixed attribute reformatting for Arnold that was causing incorrectly sampled user attributes.
  • Yeti will now only use a render license when “Overriding Cache With Inputs” is used on a cache in an interactive Maya session.
  • added userFloat and userVector attributes to Guide curves as an added utility to pass per guide custom values into the graph.

3.1.3

Released: 18/12/18

Dependencies: MtoA 3.1.0.0, Arnold 5.2.0.0, VRay 4.04, Renderman 22.3, 3Delight 12.0.113, Redshift 2.6.27, Clarisse 3.6 SP4

  • updated to Renderman 22.3.
  • fixed an issue where flood fill wasn’t working with some of the Brush tools.
  • fixed a bug which caused Arnold to crash when rendering deformed instances.

3.1.2

Released: 23/11/18

Dependencies: MtoA 3.1.0.0, Arnold 5.2.0.0, VRay 4.04, Renderman 22.2, 3Delight 12.0.113, Redshift 2.6.27, Clarisse 3.6 SP4

  • refactored how attribute reformatting was handled post graph evaluation as the previous implementation was introducing issues with instanced fibres.

3.1.1

Released: 17/11/18

Dependencies: MtoA 3.1.0.0, Arnold 5.2.0.0, VRay 4.04, Renderman 22.2, 3Delight 12.0.113, Redshift 2.6.27, Clarisse 3.6 SP4

  • resolved an interpolation issue when exporting additional Arnold user attributes.
  • updated reference node to postpone geometry transformation until full graph evaluation has completed.

3.1.0

Released: 16/11/18

Dependencies: MtoA 3.1.0.0, Arnold 5.2.0.0, VRay 4.04, Renderman 22.2, 3Delight 12.0.113, Redshift 2.6.27, Clarisse 3.6 SP4

  • updated to VRay Next (4.x).
  • updated to Renderman 22.2.
  • updated to Redshift 2.6.27.
  • Redshift support for user attributes. Float and Vector as Constant, Uniform and Vertex will be exported - be aware that Redshift currently only supports a single value per strand, even for Vertex attributes.
  • added a brush falloff UI control in the Groom Tool window for more precise control over falloff along the length of a strand.
  • Scatter will now generate du and dv vectors when generating points from a mesh to help with vector displacement. These are NOT inherited by default by the Grow node but can do so if added to the Inherit Attributes parameter.
  • added a check for Redshift API version parity and will warn the users if it doesn’t match.
  • each new Scatter node is now created with a unique random seed.
  • added customMotionStartAndEnd parameter to Arnold DSO to specify exact motion_start and motion_end parameters for generated geometry. This expects an array of two floats (or more, but only the first two values will be used).
  • Int parameters can be toggled to expression inputs.
  • Scatter Seed parameter can now take an expression to create varying distributions on a per frame basis.
  • Node Inspector parameter widgets will now default to expression input fields when expressions are being used.
  • added a Min Clipping Level to Attribute Paint viewport display and renamed Clipping Level to Max Clipping Level.
  • fixed Graph Editor High DPI rendering issues.
  • removed redundant PTC command line tools.
  • brush sizes will be maintained between Comb and Scult style tools.
  • licensing tools updated to RLM v12.4.
  • fixed an issue with nan’s being introduced into custom attributes for Arnold.
  • fixed a bug where Yeti was trying to evaluating parameters that have been removed since previous releases.
