Unwrap Texture

The Unwrap command prompts for selecting edges on the selected object as texture seams where the object's render mesh will be split in UV space.

Input

• Surface, Polysurface, Extrusion, Mesh, SubD

---

Steps

1. Start the command.

2. Select one or multiple objects, press Enter.

   Multiple selected objects will not overlap in UV space.

3. Select a mapping channel.

4. Select edges on the object.

   Use the command-line options to help selecting edges.

5. Press Enter when done.

Command-line options

Chain Chain selects the seams.

Apply Applies the seam selection.

Edit Opens the UV Editor.

Cancel Cancels the command.

MappingChannel Selects a mapping channel number for the UV mesh.

UnweldedOnly (For mesh-only) Makes only unwelded mesh edges selectable.

SymmetryTip Defines the symmetrical plane on an object to unwrap the object symmetrically.

See the Rectangle command for sub-option descriptions.

UnweldSeams (Mesh-only) Unwelds the mesh edges along the seams to avoid mapping distortion near the seams. The actual mesh geometry will be modified.

UnweldSeams=Yes (left) and No (right).

Method

Conformal Uses the Least Squares Conformal map (LSCM) algorithm to flatten 3D objects.

AngleBased Uses the Angle Based Flattening (ABF++) algorithm to flatten 3D objects.

AsRigidAsPossible Uses the As-Rigid-As-Possible (ARAP) algorithm to flatten 3D objects. ARAP keeps texture size more even across the object than LSCM and ABF.
