Material Replacer

Module: Tech · Category: Workflow · Tool ID: MaterialReplacer

Batch-find and replace materials across actors in the current level. Scans Static Meshes, Skeletal Meshes, Decals, and other placed actors. Pick source material, pick target material, click Scan, review the per-actor list, optionally narrow with checkboxes, click Replace Selected. Fully undoable.

Replacer with source + target materials picked, scan results showing 15+ actors using the source material.

When to use it

• Migrating from one master material to another across an existing level
• Replacing placeholder materials with finals
• Bulk-cleaning levels of legacy materials before deletion
• Swapping a deprecated material for a new replacement

What it isn’t for

• Don’t expect parameter remapping. Assignment is a straight material swap; parameter values come from the new MI’s defaults.
• Don’t use this for asset-side replacement. It operates on placed actors, not asset references.

Opening the tool

1. Open the EQLabs Hub and search for Material Replacer (or browse to Tech → Workflow).
2. Click the tool card.
3. Pick source + target materials, scan, replace.

6. Save the level.

Output

• Material assignment changes on selected actor components — undoable
• Clipboard. Copy Results.

Tips and gotchas

• Replacement is per-component-slot. Static Mesh + Skeletal Mesh + Decal components all replaced.
• Target material’s parameter values are used. Not the source’s. If you want to migrate parameter values, copy them via Material Preset Manager first.
• Save the level afterward. Replacement is in-memory until save.
