Arnold 7.2.0.0
Enhancements
-
MaterialX displacement shaders: MaterialX displacement shaders are now interpreted correctly. usd#1366
-
Arnold shader metadata: We now register all Arnold shader metadata in the Sdr registry. Before only the Help and Role metadata were passed to the registry. usd#1390
-
AutoTX environment variable:
HDARNOLD_auto_generate_txcan be set to override the default AutoTX behaviour in the render delegate. usd#1353 -
Driver options in the RenderProduct primitive: It is now possible to set the driver options in the RenderProduct primitive using attribute names prefixed with the driver name in the Arnold namespace. For example
arnold:driver_jpeg:qualitywill set the quality when rendering with the jpeg driver. usd#1346
Bug fixes
Arnold 7.2.1.0
Enhancements
- Convert cube, sphere, cylinder, capsule primitives as meshes in the procedural. Geometric primitives are now converted to Hydra meshes instead of Arnold primitives. usd#1318 usd#1451
- Support render delegate products for all Arnold drivers. When rendering using Hydra, with husk for example, the render delegate now uses the RenderProduct drivers. usd#1422
- Support combination of half and full precision AOVs in the procedural. The procedural can now render a combination of half- and full- precision aovs. usd#1416
- Always read RenderVar aov:name as an output layer. The
RenderVarparameter driver:parameters:aov:name is now used as the output aov layer name. usd#1408 - Support asset attributes for filenames when no tokens are present. "filename" Arnold attributes are now SdfAssetPaths in USD usd#1163

Full Changelog: Arnold-7.1.4.0...Arnold-7.1.4.3
Arnold-7.1.4.0
[7.1.4.0] - 2022-11-21
Enhancement
-
Imager support:
- #1305 Imagers can now be rendered in Hydra and the procedural through an imager node graph connected to the RenderSettings "imager" attribute.
-
Skinning:
-
Lights:
- #1294 Shader connections to mesh lights It is now possible to connect shading graphs to a mesh light color. This can be done by connecting an ArnoldNodeGraph primitive to the mesh attribute
primvars:arnold:light:shaders. - #1231 Cylinder lights: Cylinder lights are now supported in the USD procedural.
- #1294 Shader connections to mesh lights It is now possible to connect shading graphs to a mesh light color. This can be done by connecting an ArnoldNodeGraph primitive to the mesh attribute
-
Camera:
- #1271 dataWindowNDC support has been improved for batch rendering. It now adds more pixels to the output image instead of simply adjusting the frustum, when using husk or kick.
- #1225 The horizontal and vertical aperture offset attributes in the cameras are now supported, both in Hydra and in the procedural. This enables features such as render regions.
-
Render settings:
- #1235 We can now set in the USD file which RenderSetting primitive will control the render by pointing the layer metadata attribute renderSettingsPrimPath to the RenderSetting primitive.
- #1321 The aov_shader attribute of a RenderSettings primitive can now point to multiple ArnoldNodeGraph. They have to be separated by a space.
- #1259 "Abort on error" is now declared as a Hydra render setting, and can be controlled in usd_view or mayaUSD.
- #1313 The attribute "arnold:filter" of the RenderVar primitive now defaults to box instead of closest_filter.
- #1311 RenderVar aov name can be called "color" for the beauty, it was supported in the render delegate and is now supported in the procedural.
-
#1006 Improved default sampling values in Hydra The default sample values were inconsistent between interactive Hydra versus batch rendering (e.g. with husk). This was improved, and now matches the other Arnold plugins. This is an incompatible change for scenes where sampling values were left to default.
-
#1211 Shader outputs registered in Sdr: The output attributes for Arnold shaders are now registered, along with their type, in the Sdr registry. This allows for applications / plugins to expose shading trees with Arnold shaders with the correct types.
-
#1266 Environment variable to debug Hydra: In order to help debugging Hydra renders, an environment variable HDARNOLD_DEBUG_SCENE can now be set to a .ass scene filename, allowing the Arnold scene data to be saved out as the render starts.

- #1331 Fix motion blur sampling on skinned instances

Render Delegate
Arnold 7.1.3.0
[7.1.3.0] - 2022-08-03
Enhancements
Procedural
- #1161 Support dataWindowNDC: When the render settings primitive defines the attribute dataWindowNDC, it now renders accordingly in the USD reader by framing the render to the expected normalized window.
- #1170 Render products with no productName: When AOVs are defined through a render product prim that doesn't have any product name, they now render to the same filename as the beauty image.
- #1187 Instances optimizations in the procedural: When using instances, the usd procedural now relies on a usdStageCache to represent the instance prototypes, instead of re-loading the usd files on disk for each prototype.
- #800 Pinned curves: Curves pinning is now supported in the USD procedural.
Render Delegate
- #1164 Cryptomatte support in Hydra: When rendering final frames with Hydra, the cryptomatte metadatas are set in the output image.

Arnold 7.1.2.0
[7.1.2.0] - 2022-05-25
Enhancements
Procedural
- #1089 Motion Blur from Render Settings: A usd scene with Render Settings primitive can be rendered with motion blur
- #1090 Varying topologies and motion blur: Support velocity motion blur on geometries with varying topologies (mesh, curves, points)
- #1100 Support arnold primvars in instances: When an instancer has a primvar for an arnold builtin attribute (e.g. matte), we now propagate it to its instances
- #1130 Support UsdPreviewSurface displacement output: scenes where UsdPreviewSurface is used as a displacement shader, through its attribute displacement are now supported. This is needed to render the Alab scenes
- #1120 Render NurbsCurves as UsdGeomCurves: Usd Nurbs Curves were previously ignored by Arnold. They are now rendered as basic UsdGeomCurves
- #1127 Support instanceable prims with variant overrides: It is now possible to render an instanceable prim referencing another primitive, and override its variants
- #1042 Color Management: When a usd file is loaded, the color manager node is set based on render settings parameters
Render Delegate
- #1080 Mesh Lights: Geometry lights are now supported in the render delegate
- #946 Color Management: When a usd file is loaded, the color manager node is set based on render settings parameters
- #1090 Varying topologies and motion blur: Support velocity motion blur on geometries with varying topologies (mesh, curves, points)
- #1100 Support arnold primvars in instances: When an instancer has a primvar for an arnold builtin attribute (e.g. matte), we now propagate it to its instances
- #1128 Support light linking on instances: We can now support setting a point instancer, or an instanceable prim, in light linking
- #1124 Optimize nested instances in the render delegate: The memory consumption for nested instances (point instancer having another point instancer as a prototype) has reduced dramatically in Hydra
- #1092 Support per-instance velocity blur: The Arnold render delegate now supports point instancers with varying amount of instances, where velocity blur drives the motion blur
- #1141 Support shader connections to lights in Hydra: Using an ArnoldNodeGraph primitive, the Arnold render delegate now supports connecting arbitrary shading trees to light's colors
- #1141 Support lights filters in Hydra: Similarly to shader connections, arnold light filters (gobo, etc...) can now be assigned to lights, through an ArnoldNodeGraph primitive
- #1158 Improve shader dependency graph in the render delegate: The tracking of shader connections (for materials, lights, light filters, etc...) is now more robust, and fixes crashes when disconnecting or reconnecting shaders
Writer
- #1139 Usd Writer reuses eventual existing material primitives: This is needed for MayaUsd exports, so that the original mayaUsd material is kept, and Arnold shaders are assigned in the "arnold" context
