So does the mule deer have a morph to turn off the antlers if you need to?
The Antlers are a separate prop - one can just delete them or "hide" them (in Poser under the Properties window, unclick "Visible"; in DS under the Scene tab, click on the "eye" to turn off visibility.) Also if using our Antler Pack, yes one should delete the preloaded Mule Deer Antlers and then go to Props/Antler Pack and select the kind of antlers you want.
