i don't use maya often, but one of my students is making a minotaur and when he selects the chest and applies fur, the fur is only in the corner joints and mouth, not on the chest. What setting does he have wrong?
Have you got your UVs laid out? Fur needs good UV co-ordinates.
I agree with 'GregS'
Fur is based on UV space, and is not based on Surface area like some other plug-ins.
