Fixed a crash when writing pointer attributes. (#342)
- Clang 9: We now support building using Clang 9. (#252)
- Primvar translation: The procedural now uses "primvars:st" and "primvars:uv" for UV coordinates, and "normals" for "nlist" on polymeshes. (#206)
- Per-vertex UV and Normals: Per-vertex UVs and normals are now supported on polymeshes. (#222)
- Shader output connections: Support for shader output connections has been improved, including per-component connections. (#211)
- Point varying primvars: Varying primvars are now supported on point schemas. (#228)
- USDVol support: The procedural now supports USD Volumes schemas. Using grids from two different files for a single volume is not allowed. (#227)
- Serialized USD: The procedural supports creating the stage from a set of strings without requiring a file. (#235)
- Basis Curves: The procedural now supports Basis Curves. (#239)
- Boolean parameters: The procedural now supports setting boolean parameters on Arnold nodes using bool, int or long USD attributes. (#238)
- Converting between Width and Radius: Width attributes are now properly converted to Arnold's radius parameters. (#247)
- RTLD_LOCAL: RTLD_LOCAL is used instead of RTLD_GLOBAL when dlopening in the procedural. (#259)
- Left Handed Topology: Left-handed topologies are now supported, including converting the varying primvars and indices for position, normal and uv attributes. (#207)
- Motion Key mismatch: Normal and position motion keys counts are the same now. (#229)
- RGBA Primvars: RGBA primvars are now supported. (#236)
- Hydra Point Instancer: Support of the Point Instancer has been greatly improved, including instancing of volumes. (#18 and #123)
- Uniform Primvars: Uniform primvars on points are now supported.
- Pixel format conversion: The render buffers now converts between pixel formats correctly. (#245)
- Light Dirtying: Transforms are now correctly preserved when parameters are dirtied, but transforms are unchanged on lights. (#243)
- Linux Build: Building schemas using Arnold 6.0.2.0 is now supported on Linux. (#219)
- Node names for attributes: Node names are now correctly formatted and sanitized when writing node and node array attributes. (#208)
