Thanks Les. I knew there was some technology that could add channels to the body, but hadn't got to grips with it yet. This is obviously the way to go for figures which don't come with blank channels provided in their bodies such as V2. I'll see if I can build a V2 ERC injector off your example.

I may have posted the wrong file somehow... I remember seeing that some of the receiver code had gone missing, and I thought I had fixed it since my test worked. But maybe I saved the updated version somewhere other than where I thought I had. Duh. Thanks anyway for the correction.

I just checked, and the backup file that Poser file editor makes has a later time stamp than the pose file itself. That shouldn't happen..!
