UV Mapping
Updated: Mar 3, 2020
The UVing process is done in 4 main parts:
Projection. In this phase parts of the model are selected and either planar, spherical, cylindrical, or automatic projections are used. This gets initial UVs laid out, but there may be overlap.
Cutting. In this phase, parts of the model are cut and maybe even sewn back together to break off distinct sides to prepare for flattening. After this phase, you may need to create new projections from the associated selections before moving on to phase 3.
Unfolding. Here the UVs are unfolded so that the faces have the same proportions in 2d as they do in 3d. this can be done wit automatic tools such as Unfold or Layout, or Smooth UV, or by hand.
Packing. In this final stage, the UVs are packed so that they fit into the 0-1 space as tightly as possible.
