Automatic Unwrap Mapping
These are options for
how to flatten UVs when Use Automatic Map is chosen in the Objects
To Bake rollout's Mapping Coordinates group.
- Rotate Clusters
Controls whether clusters
are rotated to minimize the size of their bounding box. For example,
the bounding box of a rectangle rotated 45 degrees occupies more area
than one rotated 90 degrees. Default=on.
- Threshold Angle
The angle used to determine
the face clusters to be mapped. Default=45.0.
As faces are gathered
to be mapped, the modifier uses this parameter to determine which
faces get put in a cluster. This is the maximum angle that can exist
between faces in a cluster.
The higher this number,
the larger the clusters will be, with consequently greater distortion
introduced as a result of texture faces' proportions deviating from
their geometry-equivalent faces.
- Fill Holes
When turned on, smaller clusters
will be placed in empty spaces within larger clusters to take the
most advantage of the available mapping space. Default=on.
Controls the amount of space
between clusters. Default=0.02.
The higher this setting,
the larger the gap that appears between clusters.
Automatic Map Size group
Rendering to texture
can choose a map size for you. Automatic map sizing is enabled or
disabled by a toggle on the
rollout. The controls in this group specify
how to create the map, when Automatic Map Size is enabled. Automatic
map sizing computes the total surface area of all objects in the
selection, then multiplies that value by Scale, and creates a square
texture map of those dimensions.
The amount by which to scale
the total surface area of generated texture. Default=0.01.
- Nearest power of 2
When on, rounds the map
dimensions (length and width) to the nearest power of 2. Default=off.
The minimum size, in pixels,
of the length and width of the automatically sized map. Default=32.
The maximum size, in pixels,
of the length and width of the automatically sized map. Default=1024.
