To use Unwrella through MEL script use the command ‘unwrella’
Some of the previously available properties have been deprecated to simplify usage of the plug-in. Those properties can still be used without causing an error for backwards compatibility but they will no longer affect the plug-in operation.
-mapchannel (-mc) : string
Destination UV set. This is where the generated UV map will be stored.
-unwrap_type (-t) : int
Unwrap type used by Unwrella: 0 - Standard unwrap type optimized for organic shapes, 1 - Unwrap type for hard surface shapes, 2 - Pack existing uv data without unwrapping, 3 - Projection unwrap for directional area optimization.
-stretch (-st) : float
The amount of stretching allowed. 0.0 means no stretching is allowed, 1.0 means any amount of stretching can be used.
-padding (-pad) : int
Distance between charts in the texture.
-width (-w) : int
Texture width of the UV and the baked map.
-height (-h) : int
Texture height of the UV and the baked map.
-keep_seams (-ks) : boolean
If True the unwrapping process will retain already existing borders as long as the given constraints allow. If False all already existing borders are discarded and Unwrella places new borders autonomously.
-use_grooves (-ug) : boolean
If True the unwrapping process will automatically add borders to edges at grooves between mesh faces.
-groove_angle (-ga) : float
Defines the angle used for the automatic groove borders.
-use_ridges (-ur) : boolean
If True the unwrapping process will automatically add borders to edges at ridges between mesh faces.
-ridge_angle (-ra) : float
Defines the angle used for the automatic ridge borders.
-pack_mode (-p) : int
Specifies the packing engine used. 0: Classic, 1: Efficient, 2: High Quality
-rescale (-re) : boolean
If True the indivudial charts are rescaled depending on the amount of mesh surface they cover.
-pre_rotate (-pr) : boolean
Determines if each chart should be individually rotated into an optimized base rotation.
-rotation (-ro) : int
Defines the angle steps that each chart gets rotated by. The values 0 to 3 correspond to the buttons in the user interface.
-full_rotation (-fr) : boolean
If True counterparts for each rotation step that are rotated by 180 degrees will be considered.
-tile_numx (-tx) : int
The number of horizontal tiles along the U coordinate.
-tile_numy (-ty) : int
The maximum number of tiles to be used. If more charts exist they will be grouped together automatically.
-camera (-c) : string
The camera that is used to determine view location and direction.
-cam_angle (-ca) : float
The view angle of the camera object.
-cam_extend (-ce) : float
The tolerance angle for which backfacing polygons are included in the projection unwrap.
-cam_ortho (-co) : boolean
When set to True an orthogonal projection ignoring the view angle is used.
This example creates a sphere, applies the modifier to it and unwraps it with a very small amount of stretching.
