  • Selection Sequence option provides a way to specify the ordering of copied/pasted faces by face selection
  • If Seams option is enabled, you can also copy/paste seams
  • Strategy option provides a way to decide copy/paste UV repeatedly if a number of copied faces is differs from pasted faces

Among objects

Copy and paste UV coordinates among same topology objects.
Location 3D View > Tool shelf > Copy/Paste UV
Mode Object

[Usage]

  1. Select object whose UV you want to copy

Transfer UV

Copy and paste UV coordinates based on the mesh's topology.
Location 3D View > Tool shelf > Copy/Paste UV
Mode Edit

[Usage]

  1. Click check box Transfer UV to show Transfer UV menu
  2. Select 2 adjacent faces of the mesh whose UV you want to copy
  3. Click Copy
  4. Select 2 adjacent faces of the mesh whose UV you want to paste
  5. Click Paste

NOTICE: Copied/Pasted mesh must have the same number of faces

  • Transfer UV ignore the hidden faces.
  • You can paste UV to the multiple meshes
  • If Seams option is enabled, you can also copy/paste seams
  • If Invert Normals option is enabled, you can copy/paste to the mirrored mesh

Flip/Rotate UV

  2. Select face you want to measure texel density
  3. Click Measure
  4. You can see mesh area, UV area and density
  5. Select face you want to apply texel density.
  6. Click Apply
  • Mode option provides a way to change the calculation method of applying texel density
  • Origin option changes the UV origin after applying texel density

Preserve UV Aspect

Change assigned texture with preserving UV aspect.
Location 3D View > Tool shelf > UV Manipulation
Mode Edit

[Usage]

  1. Click check box Preserve UV Aspect to show Preserve UV Aspect menu
  2. Select face you want to change texture

Texture Lock

Preserve UV while you edit the mesh. This feature is same as "Preserve UVs" feature on 3dsmax.
Location 3D View > Tool shelf > UV Manipulation
Mode Edit

Normal Mode

[Usage]

  1. Click check box Texture Lock to show Texture Lock menu
  2. Select vertices/edges/faces which you want to preserve UV
  3. Click Lock
  4. Transform vertices/edges/faces as you like
  5. Click Unlock, you can return to the UV before locking
  • If connect option is enabled, you can keep UV connection by changing other face's UV.

Interactive mode

[Usage]

  1. Click check box Texture Lock to show Texture Lock menu
  2. Select vertices/edges/faces which you want to preserve UV
  3. Click Start
  4. Preserve UV even if you transform vertices/edges/faces

Texture Wrap

Texture wrap can set texture coordinate along to the mesh structure.
Location 3D View > Tool shelf > UV Manipulation
Mode Edit

[Usage]

  1. Click check box Texture Wrap to show Texture Wrap menu
  2. Select a face whose UV you want to refer as initial position
  3. Click Refer
  4. Select an adjacent face whose UV you want to set
  5. Click Set
  • If Set and Refer option is enabled, you don't need to click Refer after clicking Set as long as you refer same face
  • If Selection Sequence option is enabled, you can select multiple faces and apply Set. The application order follows the selection sequence
