Release Arnold 6.2.1.0 · Autodesk/arnold-usd

Common Library: Arnold-usd now includes a set of common functions and string definitions to share across multiple modules. (#466)

Half and Double precision: Storing data using half or double precision is now supported. (#672)
Velocity blur: The procedural now uses the velocity attribute to create motion keys for point-based shapes, when there are no position keys or the topology changes between frames. (#221)
NodeGraph schemas: The procedural now supports using the NodeGraph schema for shader networks. (#678)
Crease Sets: The procedural now supports crease sets on polymesh. (#694)
Purpose: Usd Purpose is now supported in the procedural. (#698)
Transform2D: The procedural now supports remapping UsdTransform2D to built-in Arnold nodes. (#517)
Multi-Threading: The procedural now use USD's WorkDispatcher which improves the performance of multi-threaded expansion in many cases. (#690)

Half and Double precision: Storing data using half or double precision is now supported. (#669)
Light and Shadow linking: The render delegate now supports light and shadow linking. (#412)
Motion blur for the Point Instancer: The render delegate now calculates motion blur when using the point instancer. (#653)
Pause and Resume: Pausing and resuming renders are now supported in the render delegate. (#595)

Write with default values: The scene format now supports optionally writing parameters with default values. (#720)

Removal of the ArnoldUSD DSO: The Schemas now work without generating a C++ library. This simplifies the build process and removes the need of installing DSOs that are not used. (#705)
