Chicken Head Setup

Continue doing this for the rest of the
nurb patches until you get a solid mesh that is half of the chickens
head. Next duplicated the head in the negative X direction. Select the
original head and on the texture window, select all of the UVs and move
them over to one side. Scale them so that they only take up half of the
texture space. This is so when we join the two head halves together we
have room for both sets of UV’s. Merge the two head and sew the UVs
together. You can normalize the UVs so they fill the Texture Space from
0 to 1. After you are done you should get a UV setup that looks like
this:
UV grid of the
head.
Notice that this gives a rough approximation of the head of the chicken
but with only one “seam” that runs down the back of the chickens head
and the openings at the top of the head and the neck. You don’t have to
do all these steps. You could have just thrown a cylindrical map on the
head when you were done converting to polys. But I have run into a lot
of bugs with Maya and the way it handles UV mapping, so this way I
decide where the mapping coordinates go. I really wish Maya had better
mapping tools for polys but this way didn’t take to long and I have a
nice set of UVs for painting.

Next we are going to tackle the beak. Same theory, but with a small
difference. Originally the beak was divided into separate parts, top and
bottom. I wanted to make the beak one piece and with nurbs this would
have been a little difficult, but with polys it’s not a big deal. One
step I am going to skip is making the beak out of patches. I am going to
jump straight into converting the beak in to polys. This will give some
UVs that are useable but the majority of them I made by selecting faces
and using a projection map. I also combined the lower beak and did a
little bit of merging vertices and remodeling until I got what I wanted.
As before I worked with half of the beak and then when I was satisfied
with it, I mirrored it and combined the pieces.
