Environment tested on:
Windows 10, Mac 10.14

  1. Resolution Note:

    Vertex colors are correctly exported, however, Unity imports meshes using the Standard shader by default. This shader does not support vertex colors. With OBJ in particular, vertex colors are not widely supported. There are only a few applications that support this unofficial addition to the OBJ spec.
