RizomUV Bridge - Blender 2.8+ (Windows)

The RizomUV Bridge provides the user with an easy to use UI which makes transferring objects and UV maps between Blender and RizomUV as simple as clicking a button.

Instruction: Install only one version, if you attempt to enable multiple versions at the same time, it will cause problems. If you have done this and cannot install: delete all versions of the RizomUV Bridge from your Blender addons, then install the latest version.

---

There are multiple versions, each clearly labeled, use whichever corresponds to your RizomUV/Blender version. 

---

IMPORTANT:

If you have any trouble updating to new versions make sure you remove the old plugin versions then restart blender before you install the new version.

---

Notable features include:

• Seamless export and import between Blender and RizomUV, original objects are untouched, only UV data is transferred back to Blender.
• Multiple UV sets support.
• User controlled convenience preferences allowing things such as excluded linked instances from export or automatically marking UV boundaries as sharp upon import.
• Supports FBX, OBJ and USD format.
• Allows saving Rizom attributes such as pins and groups when using USD format.
