Copy/Paste UV

Among faces

Copy and paste UV coordinates among same/different object's faces.

Location	3D View > Tool shelf > Copy/Paste UV
Mode	Edit

[Usage]

1. Click check box Copy/Paste UV to show Copy/Paste UV menu
2. Select faces whose UV you want to copy
3. Click Copy > (Target UV Map)
4. Select faces whose UV you want to paste
5. Click Paste > (Target UV Map)

• 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
2. Click Copy > (Target UV Map)
3. Select objects whose UV you want to paste
4. Click Paste > (Target UV Map)

• If Seams option is enabled, you can also copy/paste seams
• You can paste UV to the multiple objects

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

Flip or rotate UV.

3. Choose the axis of the mirror direction
4. Click Mirror

Move UV

Location	3D View > Tool shelf > UV Manipulation
Mode	Edit

Move UV with a mouse in 3D View. This feature is derived from below add-on.
ADDON: Move the UV from the 3D view

[Usage]

1. Click check box Move UV to show Move UV menu
2. Select vertices/edges/faces whose UV you want to move
3. Click Start
4. Press Mouse Left Button to start moving UV
5. You can move UV with mouse
6. Press Mouse Left Button to stop moving UV

• If you want to cancel moving UV, press Mouse Right Button

World Scale UV

Measure and set texel density. This feature is derived from below add-on.
[Addon] World Scale UV

Location	3D View > Tool shelf > UV Manipulation
Mode	Edit

[Usage]

1. Click check box World Scale UV to show World Scale UV menu
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
3. Select texture you want to assign
4. Click Change Image

• Origin option changes the UV origin after changing 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
5. Click Stop

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
