Hi John
You only need 3DXchange 7 Pipeline if you plan to export any iClone 7 content out to other software or game engines in FBX, Alembic or BVH formats. If all your work is to be done within iClone 7, CC and Crazytalk 8 Pipeline then you don't need 3DXchange 7 Pipeline.
You also don't need 3DXchange 7 Pipeline to use Motion Live or the available Gear Profiles like Faceware.
If you do at some point wish to upgrade to 3DXchange 7 Pipeline, just visit the page below and then click the Add-On's tab. Then if you are logged into your account you will see the upgrade price.
