Material Manager Pro: Free Blender Addon to Tame Your Material Chaos

You imported a model and now you have 47 materials named Material.001 through Material.047.

Material Manager Pro fixes this in one click.

Features

Merge Duplicates — Wood.001, Wood.002, Wood.003 all become Wood. References automatically updated across every object.

Replace Material — swap any material for another across your entire scene. Pick source and target from a dropdown.

Batch Edit — set base color, roughness, or metallic on ALL selected objects' Principled BSDF materials at once. Perfect for quick look-dev.

Select by Material — click to select every object using a specific material. Great for checking usage.

Create & Assign — create a new Principled BSDF material with custom properties and assign it to selected objects in one step.

Convert to Principled — upgrade legacy Diffuse BSDF shaders to Principled BSDF, preserving the base color.

Statistics — see total materials, unused count, duplicate count, and per-material usage across objects.
