This does not have to be an actual camera. Pick Camera - Chooses the object which determines the perspective for the unwrap. If the angle between the normals is higher than the given angle, a seam will be added. The angle defines the threshold for seam placement. If the angle between the normals is higher than the given angle, a seam will be added.Ĭut Ridges - Adds seams to edges that form a ridge. This is where the generated UV maps will be stored.Ĭut Grooves - Adds seams to edges that form a groove. If Pack Existing is selected this spinner determines the source channel for the UV data. The accompaying spinner determines from which of the original map channels the seams are taken. Please see the chapter about manually placed seams for further information. This results in unwrapping results that are more conformant with certain workflows (i.e. Keep Seams - If checked all seams that already exist on the mesh will be kept while unwrapping. 0 means no stretching is allowed, 1 means any amount of stretching can be used. Texture Stretch - The amount of stretching allowed. See Projection Unwrap for settings relating to this unwrap mode. This allows a much more efficient use of UV space is the geometry is only seen from a fixed or slightly changing perspective. Visible surfaces are distributed over the UV area while geometry not visible for the given view gets excluded. Projection unwrap - Unwraps the geometry based on a given view perspective. Pack existing - Uses the already existing UV charts and packs them together into maps without unwrapping anything. Hard surface - this mode is more suited for many architectural objects where organic unwrapping produces too fragmented results. Organic unwrapping - this mode is suited for irregular shapes. Unwrap Mode - Picks the unwrapping method. If it’s disabled each object receives its own independent UV packing without affecting chart placements of other objects. When Combine is enabled the charts of the objects are packed together into the same UV space so that they can share a texture. Combine - This option determines how unwrapping of multiple objects is handled when an instance of Unwrella is applied to multiple objects at once.
