UV Editor toolbar

UV Editor toolbar

(A) This first group of buttons contains shortcuts to the standard Unity manipulation tools. These have the same effect as the main Unity toolbar buttons.

(B) The second button group contains shortcuts to ProBuilder's Element Edit modes. When you use Manual UV Editing, this allows you to select and manipulate UVs by Vertex, Edge, or Face.

Note: When you use Auto UVs, you can only edit UVs by face. If you edit an Edge or Vertex, ProBuilder converts the selected UVs to Manual UVs.

(C) The third group of buttons contain buttons to perform the following actions:

  • In-Scene ON Scope controls: Control how Unity's standard transform tools behave.
  • In-Scene ON Texture preview: Toggle whether the UV Viewer displays the face's Texture.
  • Render UV Template button Save UV image: Create UV Templates from the current UV mapping.

In-Scene ON Scope controls

When Scope controls are on (In-Scene ON), you can use Unity's standard Move, Rotate, and Scale tools to directly manipulate UVs in the scene, without affecting geometry.

When Scope controls are off (In-Scene OFF), the Move, Rotate, and Scale tools return to normal geometry actions.

Move, Rotate, and Scale tools on a Mesh

When you use the Transform tools in the UV Viewer, you can snap to increments with the Ctrl (Windows) or Cmd (macOS) modifiers. To customize the size of these increment values, set the UV Snap Increment preference.

In-Scene ON Texture preview

When Texture preview is on (In-Scene ON), the selected face's Texture appears in the UV Viewer. This preview makes it easier to fit the UV to the Texture.

When Texture preview is off (In-Scene OFF), the Texture does not appear in the UV Viewer.

Toggle the Texture preview (OFF - ON)

Render UV Template button Save UV image

Click the Camera icon (Render UV Template button) to open the Save UV Image window. You can use this window to render a UV Template for texture map painting, atlasing, and sprite sheets.
