Quote - The dial is created on the Body actor. Animating colour parameters will create 3 dials, one each for the RGB components.

Thanks for that: found them!

Quote - The dials created by animating material room inputs won't help D|S users, as the nodes must be there for the dials to have any affect.

Dang! Well, according to that plugin, some material room nodes are at least emulated, aren't they? Guess I'll have to have a look to see if PoserSurface is and what options exist.

Thanks very much for your reply, NRuddock!
