视频预览：
Peregrine Labs公司发布了Yeti 3.5，这是其羽毛、皮毛和实例系统的最新版本，新增了对Alembic和OpenImageIO格式的支持。
本次更新是继Epic Games公司收购Shave and aHaircut之后，Yeti插件重新在美国上市以来的第一次更新。
许多现代视觉特效和动画流程中的重要部分
Yeti是一款基于节点的，以生产为中心的工具，自2011年发布以来，该插件已经成为许多视觉特效和动画工作室制作流程的一部分，使用该插件制作的最新作品包括《雷神3:诸神黄昏》和《好兆头》。
该插件支持的渲染器包括3Delight、Arnold、Clarisse、Guerilla Render、Redshift、RenderMan 和V-Ray。Foundry公司现在也明确宣布Yeti是其支持的关键技术之一。
Yeti 3.5中的新功能：支持Alembic和OpenImageIO格式，新增了体积导向模型
Yeti 3.5中新增了对视觉特效制作流程中两个关键的开放标准的支持：Alembic和OpenColorIO。
本次更新添加了新的File节点，用于在Alembic文件中读取网格和曲线数据；以及将Yeti Fur系统写入Alembic缓存的选项。
Yeti内部的纹理系统已被替换为颜色管理标准OpenColorIO。
Yeti3.5中的其他新功能包括用于控制毛发走向的体积模型，该体积模型比之前的形状匹配（Shape Matching）模型更加直观。
现在在Yeti中进行毛发设置时，毛发也可以被自动设置为高于给定的角度阈值，另外还新增了随机处理效果的选项。
     
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 (defalut) 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.
