Well here are my pumpkins...
There are 3 sets
Pumpkin1 has the middle of the 3 voicing.
Pumpkin2 has the outer 2 of the 3 voicing
Pumpkin3 has all 3 voicing.
If you add them all to your faces settings then you can get the singing separate parts...
The orange has been set up as Red = 255, Green = 55 and comes out quite nice on mine...
Hope these are of some use??
