July 2025 highlights: delivering targeted pipeline improvements across the core validation and publish systems, expanding workfile handling and versioning capabilities, and improving developer UX across ynput/ayon-core, -nuke, and -frontend. In ynput/ayon-core, we delivered Blender support in the Validate File Saved workflow with clarified documentation for unique subsets validation, implemented a skip for non-integrated instances to reduce local render validation noise, and introduced observability and readability enhancements in the publish pipeline (including prioritized container discovery and removal of legacy checks). We adopted the Workfiles API for versioning, updating the flow to use save_next_version, and extended Nuke publishing to support PSD workfiles as source images, while preserving author attribution. In ynput/ayon-nuke, error handling was strengthened by raising PublishError on render failures and a cleanup of unused attributes. In ynput/ayon-frontend, the addon development path placeholder was updated to include '/client', with a clarifying tooltip. Overall, these changes reduced validation and publishing errors, improved pipeline reliability and traceability, and broadened format support (PSD) with explicit author context."

February 2025 summary: Delivered core reliability and UX improvements across three repos (ynput/ayon-core, ynput/ayon-nuke, ynput/ayon-frontend). Key features include cross-shell subprocess escaping fixes, centralized ThreadPoolExecutor error handling, workfile template builder UX refinements, a new AttachReviewables Pyblish plugin for asset management, and config-driven USD layer defaults with task-aware profiles. Nuke loader was refactored to a reusable base (NukeGroupLoader) to reduce duplication. Frontend usability and code quality improvements were completed, including UI polish and improved logging. These efforts improved reliability, reduced manual intervention during publishes and asset workflows, and aligned defaults with project settings, delivering measurable business value and enabling smoother pipelines.

Month: 2024-11 — ynput/ayon-core: focus on stabilizing core data handling and expanding DCC compatibility. Delivered key features and fixed critical stability bugs, enabling smoother artist workflows and more reliable asset publishing in the Ayon Core. Key features delivered: - ShapeFX Loki support integrated: Loki is now a supported host in Ayon Core, enabling pre-launch hooks and validation plugins to recognize and operate when Loki is the active DCC. Major bugs fixed: - General Stability and Data Handling Fixes across UI stability, Qt6 scriptsmenu compatibility, loader widget handling, instance data access, and representation pipeline usage to improve reliability and correct data context for users. - Specific commits: - 7d23e1ac3fc29a8e8bc99ef94283f62f2b9f746f: Fix support for scriptsmenu running commands in Qt6 (e.g. PySide6 in Maya 2025) - 749984c0bff74c4491a7d6e853afa70906b1e984: Fix loader load option box widgets - 3da898b3440b5fd9ba75887205e033cc834685a2: Update client/ayon_core/pipeline/publish/publish_plugins.py - 0c80fe0ad6d48e854ba0bed5fdeba61e4bcf116f: The `_representation_conversion` method converts in-place - it does not return anything Overall impact and accomplishments: - Improved reliability across DCC environments (notably Maya 2025 with PySide6) and tighter data-context integrity, reducing debugging time and workflow interruptions. - Strengthened pre-launch validation and publish workflow resilience, increasing confidence in asset delivery. Technologies/skills demonstrated: - Python, Qt6/PySide6 integration, DCC tooling compatibility, data pipeline management, and plugin architecture development for publish pipelines.
