The current version of Orca3D (V1.x) is not compatible with Rhinoceros 6. We are currently working on a new version of Orca3D (version 2) that will run in Rhino 6, and hope to have a Work-in-Progress (WIP) version of Orca V2 available later this spring. We follow the same distribution model as McNeel in that major updates (e.g., Rhino 5 to 6 or Orca 1 to 2) are paid upgrades, while minor updates and service releases are free of charge to existing customers. Of course you can continue to use your current version of Orca3D and Rhino 5 as long as you like.
