This package contains :

• Several bug fixes.
• UI improvements (ie : support for multi-selection edits, better UI controls for time range,..)
• Simplified workflow : abc files don't need to be placed in streamingAssets, just use the asset folder and the importer will automatically copy them to streamingAssets. This also fixes issues where abc files couldn't be renamed or moved around in the asset folder.
• Added a setting to interpolate samples and calculate vertex velocities.
• Added 'turn quad edges' setting to the importer.
• support for 32 bits index buffers.
