Released: 22/03/24

Dependencies: MtoA 5.3.5.0, Arnold 7.2.5.0, V-Ray 6.20, Renderman 25.2, Redshift 3.5.24

Changes & Bug Fixes

• made sure sampled grooms with density values higher than 1.0 are handled the same was as previous releases. 
• Mesh objects are now draw in the viewport using assigned Maya shader.
• Refactored the Clump node to provide a modest speed increase when a large number of source clump curves are used.

5.0.0

Released: 26/02/24

Dependencies: MtoA 5.3.5.0, Arnold 7.2.5.0, V-Ray 6.20, Renderman 25.2, Redshift 3.5.24

Changes & Bug Fixes

• improved VP2.0 shading for more realistic interactive lighting feedback.
• XGen Interactive Grooms can now be imported into Yeti graphs.
• added a new Groom sampler which can be used to sample attributes from input Grooms and referenced by parameters in the graph.
• Groom sampler can take a specialized "length" attribute which samples the groom strands length.
• Groom deformation layers are now animatable. 
• internal optimizations and refactoring that improve overall performance.
• due to optimizations in how weights are computed we've removed all weight caching that was previously implemented, this should reduce memory usage considerably for large/dense systems.
• fibres lengths can be adjusting using the new Set Length and Length Value parameter's in the Geometric Tab of the Attribute node.
• Interactive renders now render from memory vs. using a temporary disk cache.
• implemented Feather curve attribute multipliers, these can modulate the overall effect of the curve based parameters and also provide a _mult attribute (ie. feather_width_mult) in the graph allowing graph based modulation. 
• added new transferAttribute command that will transfer attributes (including Length) between grooms.
• added Barb Density ramp to feather object to modulate density along the length of a feather.
• the File node defaults to $time vs $F for Frame Time.
• updated groom viewport representation to improve strand visibility.
• added a brush randomness parameter to randomize grooming strokes.
• exported attribute textures are now written as 32 bit vs 8 bit. 
• added marking menus for various Maya nodes.
• added Attraction parameter to Clump node to allow expression and curve Samplers to be applied more easily to control the shape of individual clumps.
• Groom component editing now supports soft selection and weighted transformation.
• Groom strand creation can be controlled by segment count as well as segment length.
• Correct weighted soft selection feedback for Feathers in Maya Viewport.
• added strand transparency and strand width controls to Maya Groom node.
• implemented support for VRay IPR via new VRay export API.
• Arnold extension is now initialized in parallel, this can be turned off by setting the environment variable YETI_ARNOLD_SERIAL_INIT to 1. 
• ported all random numbers to Rand48 for better non-repetitive characteristics.
• a memory leak visible during Alembic Export when using texture files has been resolved.
• updated pgYetiMaya.mod file to add environment variable configuration for rendering extensions.

• updated to VRay 6.20.

• updated to Redshift 3.5.24.

• toggling a selected nodes ignore state will be applied to all other selected nodes (and only within a selection).
