3.5.0
Released: 17/08/19
Dependencies: MtoA 3.3.0.0, Arnold 5.4.0.0, VRay 4.12, Renderman 22.5, 3Delight 12.0.113, Redshift 2.6.43, Clarisse 4.0 SP2b
- Updated to MtoA 3.3.0 and Arnold 5.4.0.
- Implemented Automatic Parting on Groom nodes, this uses an angle threshold to automatically modulate strand weights to make creating hair parts more easily.
- Part Randomness parameter will now modulate the painted part_randomness attribute on Grooms.
- integrated a new Volumetric guide model, all guides will default to this with the option to toggle between Volumetric (default) and Shape Matching (original) on each input guide curve.
- re-implemented Twist into new Volumetric guide model.
- added Random Twist as a new guide curve parameter.
- replaced Base and Tip Attraction with an Attraction Profile using a curve to define the shape along the length of the input Guide.
- added Max Clump Influences to the Guide node, by default it is 1 (as previous releases) but this allows users to increase the number of guides used for clumping (Attraction).
- added a new File node to read external geometry (Curves and Meshes) into the graph via Alembic files.
- added Alembic Exporter to pgYetiCommand using the -writeAlembic argument, this will write an evaluated Yeti node into an Alembic file across a frame range including multiple time samples.
- A nodes Render density, width and length will be used by default when exporting an Alembic cache but can be overridden with the -alembicDensity, -alembicWidth and -alembicLength command line parameters.
- Added a new Switch utility node.
- Integrated OpenImageIO for better resource usage and more flexible image format support.
- Added ‘Obey Density’ option for relaxation during scatter.
- added the option to select either Parametric (3.1.x and below style) or Projection (new, and default) based texture coordinates for feathers.
- Added Disable Surface Collision to brush options.
- Strand end point positions can now be locked by holding the C key while sculpting.
- A point is now drawn at the base of all Groom strands, even if zero length, to ensure better strand visualization.
- Added node deletion command to pgYetiGraph command.
- pgYetiPreRender will be removed from the render globals when the last Yeti node has been removed from a scene.
- added a Seed attribute to Braids.
- added the option to bake input mesh texture coordinates to vertices (vs. per face per vertex) in the Attribute node accessible as a vtxcoord vector attribute.
