Mm. I think a better wording might be that P4 tries once to follow the actor relationship described in the ERC slave channels. If it fails, it will "hunt" for matching channels in any other figure. If it fails there, it will delete the ERC slave channels completely. I am still confused about what P5 does. Does it perhaps fail promptly, and not go on a search through the scene for a potential matching channel? I hear different reports. Some people tell me two figures with FBMs can now be loaded into a scene without crosstalk. Others tell me the figures WILL crosstalk, even in P5. The one thing I am certain of is that tracking down ERC problems is a pain in the neck. I've gotten really, really tired of loading test scenes, having them fail in strange ways, loading new scenes, crashing Poser, etc.
