Gaffer 1.7.0.0 alpha 9

[murraystevenson]

Features

• QuantizePrimitiveVariables : Added new node for quantizing the values of primitive variables.
• DataStore : Added new node for storing large data alongside a Gaffer script, which is more efficient than storing large data inside the script file. Data is stored on the DataStore node by calling setEntry, instead of setting plug values. This node will be used as a basis of future tools that create data within Gaffer.

Improvements

• GraphEditor :
  • Changed node context menu items to operate on multiple nodes where possible (GraphEditor and how its context menu behaves when multiple nodes are selected #2783).
  • Added drag & drop from LightEditor and AttributeEditor. Dropping a location navigates to the node that created the location.
• RenderMan : Changed PxrCryptomatte's material output to use the name of the terminal shader, rather than a hash of the network. This is stable under animation. As before, the output can be customised by creating a user:__materialid attribute.
• SpreadsheetUI : Added "Output" row, showing the output value computed for each column. Cells in this row can be left-dragged to connect the column to a plug, or middle-dragged to transfer the current value.

Fixes

• FocalBlur : Fixed issue with excess alpha near depth discontinuities. This resulted in small bright edges near silhouettes where there is a sharp change in depth.
• Filter : Fixed bug with Select affected objects where only the relevant locations from one scene connected to the filter would be included in the selection instead of from all scenes connected to the filter.
• ScriptNode :
  • Fixed context updates for variables plugs with an input connection.
  • Prevented invalid input connections to variables plugs. Connections from node outputs are considered invalid because they could create a circular dependency between context variables.
• EditMenu : Added popup dialogue when errors occur during "cut" or "copy" operations.
• Shuffle nodes : Fixed bug that disabled the "+" button if a shuffle plug had an input connection ¹.
• Arnold : Fixed crash with Arnold 7.5.2 when setting the driver_exr "compression" parameter, which was previously a string but is now a string array ¹.
• IECoreArnold::ParameterAlgo : Added support for setting an array parameter with a StringData or BoolData. This is treated as equivalent to setting the array parameter to a one element array ¹.

API

• GraphEditor : Added an optional argument to nodeContextMenuSignal() to request a signal that will pass a list of nodes to the handler, rather than a single node. This can be used to register menu items that will act on multiple nodes.
• Spreadsheet : Added support for spreadsheet:outputRowVisible metadata, which can be used to hide the output row.
• TestCase : Added alternateMountTemporaryDirectory() for testing behaviour when moving files between directories on different filesystems.

Breaking Changes

• RenderMan : Changed the default values used for PxrCryptomatte's material output.
• ScriptNode : Changed preconditions for calling serialiseToFile. If the desired behaviour is that the ScriptNode in memory will be now be associated with the new file ( ie. a saveAs operation ), then the caller is responsible for setting ScriptNode.fileNamePlug() to the new file name before calling serialiseToFile.
