grass and fur

[jmcewen]

The grass color shader grows grass on the top sides of things.  Is there a way to make the grass grow on all surfaces? Often i just make 2 of an object, with one upside down render them both, then turn the upside down one right side up and paste it so it occupies the same place the right side up object does just to cover the bald side.  Otherwise it looks like things have strange emo haircuts.

 

As an alternative question to reach the same end, I have been using the grass shader to make hair and fur type textures. Is there a better way to go about this.  I played with the noise textures and the grass shader is just so much more convenient until i end up with a bald spot on a complex object.
