MATERIAL MULTI-ASSIGNMENT TOOL DOCUMENTATION

Introduction/Objective 

The Material Multi-Assignment Tool in Unreal Engine enhances asset preparation efficiency by allowing users to apply materials to multiple slots of multiple assets simultaneously. It saves time and effort for developers, artists, and designers.

Tool Overview

• Assign the same materials to multiple assets (both skeletal and static meshes).

• Assign individual materials to each material slot within an asset.

• Automatically assign the same materials to selected or all slots.

Installation and Setup

1. Copy the editor utility widget (uasset file) to your content browser.

2. Right-click on the asset and choose "Run Editor Utility Widget" from the menu.

How to Use

1. Click the "+" button in the material tab to add material slots.

2. Specify the number of desired slots.

3. Assign a material or material instance to each slot using the tool's interface.

4. Toggle the "Assign Empty Slots with Last Material" button:

5. Enable: Assign the last material in the index to all remaining slots.

6. Disable: Leave extra slots unchanged.

7. Select the assets in the content browser where the changes should be applied.

8. Press the Assign button at the bottom. fk

The resulting images will vary depending on whether you have enabled "Assign Empty Slots with Last Material". Best Practices

• Avoid using the tool on assets with many copies in the level to prevent crashes caused by intense parallel computations.

• Utilize the "Assign Empty Slots with Last Material" toggle on a single slot to assign the same material to all slots.
