Blender Addon to import/export Wavefront OBJ with Vertex Color. This addon is based on the official blender addon.

So far the testing is not really sufficient. If you have any troubles importing / exporting your .obj data, please report an issue.

Installation

1. Download zip of this repository.
2. Open your blender 2.8
3. Navigate to Preferences --> Add-ons
4. Press Install and select the downloaded zip
5. Enable the addon
6. Done. You can import Wavefront OBJ with vertex color from File --> Import --> Wavefront with VC (.obj), or export it in the same way.
