MatGeo

MatGeo

This addon synchronizes Shader Node Group inputs with attributes stored via Geometry Nodes, enabling material instancing and togglable material application, and facilitates quicker asset creation by saving the control logic into a standard Geometry Node setup operable by users without the addon.

Features

Geometry Node Setup and Material Scope

• Converted Node Groups on the same material are added to the same Geometry Node setup.
• Converting a Group on a different material will automatically create a new, separate Geometry Node setup for that material.
• On conversion, group socket settings such as Description, Subtype, Default, and Min/Max are transferred to the Geometry Node parameters to be displayed in the Modifiers Panel.

Parameter Types

• Float
• Integer
• Boolean
• Vector
• Color
• Image Textures are not currently supported.

Context Menu Operators

• Convert To MatGeo Group: Transforms the selected, standard Shader Node Group into a MatGeo Group, creating and linking the necessary attributes.
• Update MatGeo Group: Manually refreshes the Geometry Node tree and attribute storage to reflect any user changes (new or removed inputs) made to the original Shader Group.
• Revert MatGeo Group: Deletes all generated MatGeo-related nodes and attributes of the selected group, restoring the original Shader Node Group.

Warning System

• Empty Group Conversion: Trying to convert a group without any inputs will prompt an error, as it will not provide any control via Geometry Nodes.
• Duplicate Naming: Trying to convert a group that has the same name as another group within the same material will prompt an error.
