# Blender workshop outlines new layered actions and animation filtering system

> **Key takeaway:** Blender is replacing its 17-year-old animation filtering system with a more flexible, action-centric hierarchy to improve data management in animation editors.

## Summary
The Blender Animation & Rigging module has released the outcomes of its September 2026 workshop, detailing a major overhaul of how animation data is displayed and managed. The project focuses on replacing the legacy animation filtering system, which has been in place since Blender 2.50, with a modern architecture designed for the current Slotted Actions workflow.

This update targets the Dope Sheet, Action Editor, and Graph Editor, aiming to resolve long-standing issues where object data and materials were redundantly displayed. By shifting from an object-oriented view to an animation-oriented view, the new system allows users to manage complex relationships between multiple objects, meshes, and materials through a single unified Action.

## Technical overhaul of animation data hierarchy
- **Animation Filtering Replacement:** The new system decouples data gathering from hierarchy building, allowing metadata (Action, Layer, Group, Object, or Bone) to be attached to F-Curves and Grease Pencil layers for more flexible rendering.
- **Action-Centric Hierarchy:** Instead of mirroring the Outliner, the new channel list places the Action at the top level, grouping all related object transforms, mesh data, and materials under a single animation block.
- **Minimal Grouping Feature:** A new filtering option can automatically collapse redundant summary channels and groupings that only contain a single item, reducing vertical clutter in the UI.
- **Data Redundancy Fix:** The proposed architecture ensures that shared data-blocks, such as a single Mesh or Material used by multiple objects, are displayed only once at the same level as the objects rather than being repeated under every user.

## Why it matters
This development significantly improves the professional animation workflow within Blender by reducing UI clutter and data redundancy. For technical animators and riggers, the transition to an action-oriented view provides much clearer control over complex, multi-object character and prop animations.
