About Rizomuv Bridge – Blender 2.8+ (Windows & Macos)

RizomUV Bridge, developed by Matt Ashpole, is a GPL‑licensed Blender add‑on that moves objects and UV maps between Blender and RizomUV using a simple button interface. It supports both export and import, preserving the original objects while only bringing UV information back into Blender. The add‑on handles multiple UV sets and works with FBX, OBJ, and USD formats; when using USD it can also retain RizomUV attributes such as pins and groups. User preferences allow exclusion of linked instances from export and optional marking of UV boundaries as sharp on import. Separate versions are provided for specific Blender (2.8‑5.0) and RizomUV combinations; only one version should be enabled at a time to avoid conflicts.
