🎯 Select Objects with Material

How: Click the select icon (cursor icon) next to any material name.

What it does: Instantly selects all objects in your scene that use this material.

Note: If some objects are hidden, you'll receive a warning message listing their names in the info bar.

Use case: Quickly find and modify all objects using a specific material.

🗑️ Delete Single Material

How: Click the trash icon next to any material name.

What it does: Removes the material from all objects using it AND deletes it from the Blender file completely.

⚠️ Warning: This action cannot be undone (except via Ctrl+Z immediately after).

Use case: Clean up unused or unwanted materials from your project.

🧹 Delete All Materials and Slots

How: Select objects in your scene, then click the "Delete All Materials and Slots" button at the bottom of the Material Manager.

What it does: Removes ALL material slots from the selected objects. Materials remain in the Blender file but are no longer assigned to those objects.

Use case: Quickly clean up imported models, prepare objects for new materials, or reset material assignments.

Finding and Removing Orphaned Materials

Look for materials marked with 0 - these are unused and safe to delete. Removing them can significantly reduce your .blend file size, especially in complex projects.

Organizing Material Libraries

Enable fake user (marked with F) on materials you want to keep in your library even if they're not currently used. This prevents Blender from removing them when you clean up unused data.

Bulk Operations

For maximum efficiency: Select multiple objects in the viewport first, then use "Delete All Materials and Slots" to clear them all at once. This is much faster than deleting material slots one by one.

Regular Scene Cleanup

Make it a habit to review materials with 0 indicator periodically. This keeps your projects organized and prevents file bloat over time.

Working with Hidden Objects

When you select objects using a material, pay attention to warnings about hidden objects. You may need to unhide collections or objects to fully manage material assignments.

Scenario: "I imported a model and it has 50+ materials I don't need"

Solution: Select the imported objects → Click "Delete All Materials and Slots" → Delete the now-unused materials (marked with 0)

Scenario: "I want to find all objects using a specific material"

Solution: Click the select icon next to that material name - all objects using it will be selected automatically

Scenario: "My file is getting too large"

Solution: Review all materials with 0 indicator and delete unused ones to reduce file size

Scenario: "I want to keep this material for later even though it's not used"

Solution: Enable fake user in Blender's material settings - it will show F indicator
