View

Use the standard camera move keys (alt + the middle mouse button and alt + the right mouse button) to move around the texture view.

Toolbar

Most of the items on the texture editor toolbar are shortcuts for actions in the menus. Right-click a button to show its options.

UV position buttons

Flip UVs U, Flip UVs V

Rotate UVs clockwise, Rotate UVs counterclockwise

Cut UVs along selection

Sew UVs

Move and Sew UVs

Split selected UV

    Separates UVs from each other along the edges connected to the selected UV points, creating borders. Shortcut for the texture editor's Polygons > Split UVs.

Layout UVs

Cycle U and V

    Rotates the U and V values of the selected polygon.

Align Min U, Align Max U, Align Min V, Align Max V

Move UVs to grid

    Moves every selected UV to its nearest grid intersection in texture space. Shortcut for Edit Polygons >Texture >Grid UVs.

    To change the grid, right-click the Toggle Grid button on the toolbar.

Relax UVs

Isolate Selection buttons

These buttons let you work on a subset of UV faces while hiding the rest.

Show only a subset of all UVs

Toggle isolation

    Switches between showing all UVs and only the isolated UVs. Shortcut for View > Isolate Select > View Set.

Add selected to isolation

    Adds the selected UVs to the isolated subset. When you click the Toggle isolation button the selected UVs will be visible. Shortcut for View > Isolate Select > Add Selected.

Removed selected from isolation

    Removes the selected UVs from the isolated subset. Shortcut for View > Isolate Select > Remove Selected.

Remove all

    Clears the isolated subset. You can then select a new set of UVs and click Toggle isolation to isolate them. Shortcut for View > Isolate Select > Remove All.

View buttons

Texture image

    Shows or hides the texture image. Shortcut for Image > Display Image.

Image ratio

    Switches between showing square texture space and texture space with the same ratio of width to height as the image. Shortcut for Image > Use Image Ratio.

Bake editor texture

    Bakes the texture and stores it in memory. See Dim Image. Shortcut for Image > UV Texture Editor Baking.

Force editor texture rebake

    Rebakes the texture. If you turn on Bake Editor Texture or Image > UV Texture Editor Baking, you must rebake the texture (using Force Editor Texture Rebake) after making changes to the texture (File node and place2dTexture node attributes) in order to see the effect of those changes.

Toggle grid

    Shows or hides the grid. Shortcut for View > Grid.

Toggle filtered pixels

    Switches the background image between hardware texture filtering and sharply defined pixels. Shortcut for Images > Unfiltered Image.

    These two buttons switch between showing the RGB (color) channels of the image and the Alpha (transparency) channel. Shortcuts for Image > Display RGB Channels and Image > Display Alpha Channels.

UV edit buttons

U coordinate, V coordinate

    Show the coordinates of the selected UVs. Edit the text boxes and press Enter to move the points.

    The UV coordinates in the text boxes on the toolbar do not update automatically as you move the selected UV point. Click the refresh button to update the values in the text boxes.

Copy/paste faces or UVs

    Switches the Copy and Paste buttons on the toolbar between working on UVs and UV faces.

Copy

    Copies the selected UV points or faces (depending on the Copy/paste faces or UVs button) to the clipboard.

Paste
