DS Cleanup Optimizer is an Unreal Engine editor utility plugin designed for Datasmith and Archviz cleanup workflows.

It provides a compact dockable Editor Utility Widget to help artists and technical users clean imported scenes faster, directly inside the Unreal Editor.

With DS Cleanup Optimizer, you can merge viewport / outliner selected Static Mesh Actors, align pivots, analyze material usage, consolidate equivalent duplicate materials, remove duplicate material assets through Unreal Engine's standard asset consolidation workflow, save modified packages, and fix redirectors in a selected target folder.

The plugin is focused on practical production cleanup tasks commonly needed after Datasmith and architectural visualization imports.

Main workflows:

Merge & Pivot

Merge viewport / outliner selected Static Mesh Actors into a new generated Static Mesh asset using a configurable asset name, output folder, and pivot policy.

The tool supports practical pivot placement options for cleanup and optimization workflows:

• Bottom Center

• Geometric Center

• Top Center
  
  

Materials

Analyze viewport / outliner selected Static Mesh Actors to inspect material slots, unique materials, material groups, and duplicate material candidates.

Material duplicate detection is based on safe equivalence checks, not only material names. The plugin compares relevant material properties such as parent material, base material, scalar parameters, vector/color parameters, and texture parameters before considering materials equivalent.

The Consolidate Materials workflow replaces equivalent duplicate material references with a canonical material without deleting assets.

The Consolidate + Delete Safe Duplicates workflow goes further by using Unreal Engine's standard asset consolidation process before removing duplicate material assets. This helps replace references to duplicate materials in loaded assets, components, and Datasmith-related data before the duplicate assets are removed.

If Unreal Engine cannot safely consolidate a duplicate material asset, the plugin keeps it protected and reports it in the Operation Result panel.

Save & Redirectors

Save modified project packages, fix redirectors in a selected folder, or run a complete Save + Fix Redirectors finalization workflow.

The combined Save + Fix Redirectors workflow runs:

1. Initial package save

2. Redirector cleanup in the selected target folder

3. Final package save
   

The Operation Result panel displays a detailed summary for each step, including success state, saved packages, fixed redirectors, remaining redirectors, and overall success.

Designed for:

• Archviz artists

• Datasmith users

• Technical artists

• Unreal Engine visualization teams

• Environment artists working with imported scenes

• Users who need faster scene cleanup after imports
  
  

Notes:

• No content included - just the plugin (tool).

• All "selected actors" dependent actions are meant for viewport / outliner selected static meshes and/or actors.

• DS Cleanup Optimizer is an editor-only tool. It is not intended for runtime gameplay use.

• The current version focuses on Static Mesh Actor cleanup, material analysis, equivalent duplicate material consolidation, duplicate material asset cleanup, package saving, and redirector fixing.

• For Datasmith scenes, destructive cleanup operations are recommended after the scene has reached a cleanup or finalization stage. If you still rely on Datasmith reimport or Direct Link synchronization, source updates may recreate materials, restore assignments, or generate new duplicates depending on the source file and import settings.
