Gaffer 1.7.0.0 alpha 6

[murraystevenson]

Features

• SceneStats : Added a new node for computing aggregate scene statistics.
• SceneInspector : Added Statistics tab with aggregated geometry statistics for the entire scene.

Improvements

• Outputs : Added output presets for RenderMan's NPR AOVs.
• SceneWriter : Defaulted to writing OSL shaders in a format compatible with hdPrman, for rendering in usdview and other Hydra-based applications.

Fixes

• Arnold :
  • Fixed fallback to a facing ratio shader when a shader is removed during an interactive render.
  • Fixed crash attempting to render with a shader that doesn't exist.
• Viewer : Fixed regression introduced in 1.6.16.0 that prevented visualisation of the renderer-specific camera visibility and matte attributes authored by the Render Pass Editor's render adaptors ¹.
• RenderMan :
  • Fixed R10043 warning when using PxrDisplace ¹.
  • Fixed automatic creation of required AOVs for PxrStylized filters in XPU ¹.
• Catalogue : Fixed errors caused by undoing an image deletion or snapshot.
• Gaffer module : Fixed bug preventing environment() from returning environment variables modified after startup on macOS.

API

• DictPath : Added support for subclassing, without the need to override copy() or _children().
• PlugCreationGadget : Added counterpart to PlugCreationWidget, allowing plugs to be created easily in the GraphEditor.
• PlugVisibilityGadget : Added gadget for managing plug visibility in the GraphEditor.

Breaking Changes

• ShaderUI : Removed PlugAdder. Use GafferUI.PlugVisibilityGadget instead.
• SceneWriter : Changed writing of OSL shaders to USD. Set IECOREUSD_WRITE_CONFORMANT_OSL_SHADERS=0 to revert to the default behaviour from Gaffer 1.6.
• Catalogue : Removed support for image order metadata from versions prior to 1.4.0.0. In the unlikely event this is needed, reorder and resave from Gaffer 1.6.

Build

• Fixed errors building gaffer executable on macOS ².
