When you select this edge in the scene view, notice that two
corresponding shell edges also get selected in the UV Texture Editor. This
indicates the following:
The selected edge is shared by two faces; the front and the top.
Selecting the top front edge in the scene view, identifies the
corresponding front and top UV shells for the box. (Indicated by the
selection in the UV Texture Editor.)
This is useful when you need to understand how the various UV shells
relate to each other, especially when you have many UV shells for a model
in the scene; for example, when you sew two UV shell edges together.
In the steps that follow you select edges in the UV Texture Editor so you can
sew them together.
Sewing UVs
Sewing UV shells together merges the UV shells along a shared edge that you
specify. Sewing UVs is useful for the following reasons:
You can move and modify the UV shells as larger contiguous texture units.
This makes it more efficient to match the UVs to the texture in many
situations.
Texture maps can appear more uniform across texture borders when the
texture is applied to one or more sewn UV shells compared to many
separate UV shells. Sewing shells together reduces the chance that an
unwanted texture mismatch occurs along the texture edge.
To sew shell edges together in the UV Texture Editor
1 In the scene view, ensure that only the top front edge of the cracker box
is still selected.
When the top front edge is selected in the scene view, the top edge of
one of the large UV shells is also selected as well as the left side of the
middle UV shell in the top row of the UV Texture Editor. For the cracker
box texture map, you need to sew these together so they correlate to the
map correctly.
