Aton v1.3.7

Added Nuke v12.1 support
Added Arnold v6.0 core support

Houdini specific notes

• Fixed issues with HtoA 4.3+
• Disabled undo stack during overrides

Aton v1.3.6

New Operator Aton: operator_aton is designed to replace all output drivers with aton driver at render time. In DCC apps like Houdini or Katana where the driver selection is not exposed in the UI, this can come handy to use Aton without extra scripts.

Added metadata support: All the information that Aton has on its framebuffers is now stored in the node as a metadata.

Render region improvements.

• Added Fit button in render region to fit the Nuke window.
• Clipboard data is now normalised to work better with multiple resolutions.

Added Nuke v12.0 support

Houdini specific notes

• Added Open and Select actions in the output context
• Added progressive toggle checkbox.
• Disables adaptive sampling if Camera AA is overridden
• Fixed pixel aspect ratio override.

Stability improvements and bug fixes:

• Fixes copy render region issue if Aton node existed in the Nuke script before.

Aton v1.3.5

Simultaneous render sessions: Multiple render sessions can now simultaneously be launched using the same port number.

Distributive rendering on the farm: The frame can be split into smaller tiles and distributed on the local render farm via region arguments. It's fully farm manager agnostic, meaning you have to sub-class and implement empty virtual methods in the python script in order to get it to work for the given farm requirements. At this moment this feature is only available for Houdini, but similar scripts should work fine for the other DCC apps too

Houdini specific notes

• General UI improvements
• Added sequence rendering support
• Stores override settings per selected output rop
• Added filter box for output rops to use with wildcards

Stability improvements and bug fixes

• Sets correct frame range in Multiple Frames mode

Aton v1.3.1

Nuke GUI improvements

• Added Reset Region button
• Remove multiple selection of snapshots

Houdini GUI improvements
Added Nuke v11.3 and Arnold v5.3 core support
Stability improvements and bug fixes

Aton v1.3.0

Houdini support: Initial support for SideFX Houdini includes the following

• MultiFrame IPR with ROPs as Render Layers
• Camera, Resolution, Sampling and Bucket Scanning Overrides
• Render Region and Overscan options
• Ignore Features for Diagnostics
• Live Camera

HtoA implementation is based on the research article from Ryan Heniser, but the workflow is very similar to Maya and Cinema 4D.

Added Nuke v11.2 and Arnold v5.2 Core support

Auto Snapshots: Each IPR session is now automatically being kept in memory with options to take, rename, reorder and remove the snapshots. Use write to disk options to permanently store them, as it was done before with capturing.

Render Layers: Render Layer names will show up as a prefix for snapshot's name on the stack. There is an arbitrary output entry in the Arnold driver which can be set by a script.

Render Region: Region handles have been added in the node, which accelerates the workflow. It's still possible to use a crop nodes too.

Status Bar Improvements:

• Added Render Layer Name and Sampling Settings.
• Status bar is now active at render time and grey when it's idle.

Stability improvements and bug fixes:

• Fixed an issue with colour picker not always showing up at render time.
• Incoming Pixel Aspect Ratio is now respected by the Format.
• Fixed the progress for Render Region not showing up correctly.
• Fixed a various threading issues causing to random crashes.
• Fixed a crash with driver when the specified port is being used.

Aton v1.2.2

• Added Nuke v11.1 and Maya 2018 support
• Maya UI improvments and bug fixes

Aton v1.2.1

• Added Arnold 5 core support
• Added support for ID AOVs
• Stability improvements and bug fixes

Aton v1.2.0

• Cinema 4D support: Initial support for Cinema 4D includes Multi frame IPR with AOVs, Render region with overscan, Feature Overrides, Live Camera and Sequence Rendering. Please note that it requires C4DtoA v1.6.0 or higher.
• Added Nuke v10.5 support
• Dockable UI in Maya: By default Aton UI in Maya is now docked at right corner.
• Stability improvements and bug fixes

Aton v1.1.5

• Live Camera support: By Enabling the Live Camera checkbox, Aton will create an interactive camera node in Nuke, which will update during IPR and frame change.
• Extra Host improvements: It's now possible to stream the rendering to Extra Host, without necessarily having a local Nuke session opened.

Aton v1.1.4

• Overscan support: Setup the overscan during IPR, and then automatically Set current values in the Scene Render Settings.
• Sequence Rendering: New rendering mode has been added from Dan Bradham, allowing to batch render a multiple frames at one go.
• Extra Host support: Simultaneously stream the rendering process to an extra machine in the same network.
• Stability improvements and bug fixes: Fixed a crash when changing the resolution frequently during IPR.
