Material Parameter Name Surgeon is an editor plugin commandlet that rewrites Blueprint parameter calls after a material parameter rename. Material instances follow renames by GUID, but Blueprint calls use plain names and break. Find in Blueprints cannot match nodes to materials. The plugin traces calls to dynamic instances, component slots, or collections, rewrites matching parameter calls, and skips ambiguous cases. It logs modified packages, compiles touched Blueprints, and returns a CI exit code. With no target material specified, it audits a folder.
The code was written with AI tools and tested in the engine. Available for $14.99:
