About this asset

MPB Generator is a Unity Editor tool designed to simplify MaterialPropertyBlock workflows.

It generates editable shader properties from an existing Material, then applies those values to a Renderer using MaterialPropertyBlock. This allows you to create per-object or per-material-slot shader variations without duplicating Materials or modifying shared Material assets.

The package includes two workflows:

  • MPBGenerator: A simple single-slot component.
  • MPBGeneratorList: An advanced multi-slot component for Renderers using multiple Materials.

MPB Generator can also read Shader Graph Blackboard categories to organize generated properties in a cleaner Inspector layout.

It is useful for decals, hit effects, blood splatter materials, props, shader debugging, per-object visual variations, and workflows where multiple objects share the same Material but need different shader values.

The package includes English and French documentation, along with a Blood Splatter demo scene demonstrating the tool's functionality.

From the publisher's Asset Store listing.

  • Custom icon functionality may be unavailable in older Unity versions.

Render Pipeline Compatibility

  • The core editor tool is render-pipeline independent.
