ockham,

I don't know if this is a problem of Poser 4.0. As far as I remember, I've used ERC in props running Poser 4.0 and Poser 4.0.3 (for Mac OS). Are you on a PC?

BTW, the hierarchy (sort order) of master and slave channels shouldn't matter in pp2 libraries. And the NO_FIG keyword isn't required. When I first tried ERC code in a prop, I've chosen the prop name. When I saved the library, Poser replaced the prop name by NO_FIG. That's how I found the keyword.

Mac,

I'm finishing chapter 10 of the tutorial ('Variable Slave Deformer Range'). I think this is the last chapter. Do you like to beta test the tutorial?
