Rule Action - Material Override Parameters
Overview
Material Override Parameters is a powerful feature within Mimeeq's 3D configurator that allows you to dynamically modify material properties without creating multiple materials. This feature enables you to create more flexible and responsive configurators while significantly reducing setup time and resource requirements.
With Material Override Parameters, you can:
Change material colors dynamically
Swap textures based on user selections
Modify material properties like glossiness, roughness, and metallicness
Connect material changes to color pickers and other UI elements
When to Use Material Override Parameters
This feature is particularly valuable when:
You need to offer many color or texture variations for the same component
You want to dynamically change material properties based on user selections
You need to connect custom color pickers to your materials
You want to avoid creating numerous nearly-identical materials that only differ in one property
Setting Up Material Override Parameters
Step 1: Create and Configure the Action
Navigate to the Actions/Rules section in your configurator
Create a new action and select "Override Material Parameters"
Configure when the action should run:
Always: The override applies at all times
Conditional: The override only applies when specific conditions are met
Step 2: Define Trigger Conditions
Like all actions in Mimeeq, you need to set up a trigger that determines when the material override occurs:
Always Active: The override is applied continuously
Option-Based: The override is triggered when a specific option is selected
Step 3: Select Target Meshes
Choose which meshes will have their materials overridden.
Step 4: Configure Material Parameters
After selecting your target meshes, click "Set Material" to open the material override modal. This interface displays all available material properties that can be modified:
Albedo color
Albedo texture
Metallic texture
Metallic factor
Roughness
Normal map
And many other material properties
Modified parameters are marked with a green tag for easy identification.
Common Use Cases
1. Dynamic Color Changes
One of the most common uses is to override the albedo (base) color of a material:
Select the target meshes
Open the material parameter modal
Modify the albedo color
Save your changes
2. Connection with Color Pickers
You can connect a material override to a color picker widget:
Check the "Set color from a color picker" option
Select your color picker source
Create a trigger that activates when the color picker is used
This allows for custom color selection beyond predefined options.
3. Dynamic Texture Switching
One of the most powerful applications is dynamically switching textures:
Static Texture Override
Select "Override Albedo Texture"
Choose "Static" mode
Select a specific texture to use as replacement
Dynamic Texture Override
Select "Override Albedo Texture"
Choose "Dynamic" mode
Define a pattern using curly brackets to reference option codes: {optionCode}.jpg
Bulk Material Management
The dynamic texture override feature can dramatically reduce setup time for large material libraries:
Upload your textures to the media library (ensure filenames have no spaces)
Create an option set for your textures
Bulk add textures to the option set
Create one material override rule referencing the option codes
When options change, the system dynamically loads the corresponding texture
This approach allows you to manage 100+ materials through a single rule rather than creating each material individually.
Best Practices
Filename Format: Ensure texture filenames don't contain spaces
Texture Organization: Keep textures for dynamic overrides in a dedicated folder
Getting Started
Try creating a simple material override rule to get familiar with the functionality. Once you understand the basics, you can create more complex dynamic material systems.
