Turn model organization into clean material structure.
Ultimate Material Manager Guide
A professional material workflow for SketchUp. Learn how to install, activate, structure, assign, replace, transform, and prepare materials for rendering.
What UMM Is
Ultimate Material Manager brings a structured material workflow to SketchUp. It helps you reduce repetitive manual work, organize materials clearly, and prepare models for rendering workflows in Twinmotion, V-Ray, Unreal Engine, D5, and other downstream tools.
UMM does not replace SketchUp's native model behavior. It applies changes directly to the model using native SketchUp materials, so collaborators can open the file without needing additional setup.
Turn model organization into clean material structure.
Apply materials directly to selected geometry.
Swap materials across selections or the full model.
Adjust texture mapping, scale, rotation, and UV flow.
Apply to Faces moves materials from groups and components down to faces, then clears the containers. Perfect for 3D Warehouse or client models.

Interface
UMM is organized around the material workflow: structure, assignment, replacement, texture control, cleanup, and inspection.
Save texture-ready material sets, batch rename materials, and reload shared libraries into any model.
Swap one material for another across the model or a selection.
Adjust mapping style, scale, rotation, offset, and UV flow.
Turn Outliner organization into a structured material setup.
Run diagnostics, create materials, merge duplicates, purge unused materials, and remove unwanted assignments.
Workflow
Most UMM actions are selection-based.
Assign, replace, remove, transform, inspect, or clean up.
Use structured materials to move faster in Twinmotion, V-Ray, Unreal, or D5.
Materials
Material Cards show the materials in your model with fast actions for everyday work.
Apply the material to selected objects or faces.
Open material editing controls.
Rename the material.
Inspect where the material is used.
Create a duplicate material.
Highlight geometry using that material.
Texture Transform
Mapping tools for architectural surfaces, roads, walkways, trims, panels, and repeatable texture setup.
Texture Transform is included in UMM 1.6.8 Early Access. It brings mapping workflows, surface analysis, UV preview, and precise mapping controls into the same material preparation environment.
Applies a fast mapping pass that responds to the orientation of selected geometry.
Returns selected surfaces to a clean mapping baseline.
Useful for box-like forms and architectural volumes.
Useful for cylindrical or rounded forms.
For long continuous runs such as roads, paths, walkways, or trims.
For strip-like forms such as fascias, edge bands, and linear surfaces.
Standard texture mapping workflow.
For quad-based surface mapping workflows.
Flip texture direction horizontally or vertically.
Surface Analysis helps users understand the selected textured faces and suggests mapping direction or workflow hints where possible.
Preview Mapping lets users inspect UV scale, rotation, and surface flow before committing to a mapping strategy.
Use Shared Surface to treat segmented geometry as one continuous UV surface, or Individual Faces to adjust each face independently for precise control.
Core Tool
Materializer is the core workflow in UMM. It converts model structure into a clean material setup based on your SketchUp Outliner organization.
Use this when you want to move from a clean, unmaterialized model to a structured material setup quickly.
Materializer works best on clean model structure and is designed to transform Outliner organization into a structured material setup.
Scans the full model and creates materials from model structure.
Limits the operation to selected groups or components.
Early material setup, render preparation, placeholder materials, clean IDs, and downstream replacement workflows.
Settings
Settings let users adapt UMM to their workflow, screen size, and material assignment preferences.
Use this when you want UMM to replace existing face materials inside the selected scope. This is useful when cleaning up imported models, replacing placeholder materials, or forcing a clean material assignment.
Use this when you want to protect faces that already have materials. UMM will only apply materials where no existing face paint should be replaced.
When enabled, UMM can apply material assignments to both front and back faces. This is useful when preparing models for rendering workflows where backside visibility, face orientation, or exported material consistency matters.
Use UI Scale to make the interface more comfortable on different displays.
Controls spacing and control height. Comfortable mode is easier to read, while compact modes are useful when screen space is limited.
Users can choose whether UMM tools stay docked in a single drawer-based window or open as separate windows and presets. Single Window / Drawers is recommended for most users.
Drawer settings control whether panels open on the left, right, or both sides, including Material Library, Replace Materials, Texture Transform, animation, and reset window layout.
Material Logic
SketchUp allows materials to exist in several different places. That flexibility is useful, but larger models can become harder to understand when materials are split between faces, groups, components, imports, and older project structure.
UMM is designed to help create a more predictable material workflow that behaves consistently across editing, rendering, exporting, and collaboration.
Applied directly to geometry. This is usually the clearest place for final materials.
Applied to a group container and visible through faces that still use the Default material.
Applied to a component instance and visible through Default faces inside that instance.
For most professional workflows, final materials are easiest to manage when they are applied directly to faces. This keeps material ownership clear, makes edits more predictable, improves renderer imports, and makes troubleshooting faster when a model is handed to another artist or visualization tool.
Container materials can still be useful, but they are harder to reason about when a model becomes large, nested, or shared across a team. UMM helps you normalize that structure without forcing SketchUp to behave like a different application.
Some UMM tools intentionally skip edits when changing a shared component could affect instances outside the current selection. This protects the model from unintended changes elsewhere while keeping bulk operations safer and more predictable.
If you work with imported models, downloaded assets, older SketchUp projects, or collaborative files, consider running Material Diagnostics followed by Apply To Faces (Preserve Look). That creates a cleaner starting point for future editing.

Renderer Handoff
Ultimate Material Manager is not a renderer. It prepares material structure before rendering, reducing downstream cleanup and replacement work.
Build cleaner material structure before import and reduce replacement work.
Organize materials before assigning final render materials.
Prepare clean material IDs and structured imports.
Reduce manual material cleanup before visualization.
