View Tool

Top  Previous  Next

 

 

The View tool is used modify the texture preview appearing in the Canvas workspace.  It can be selected from the Canvas toolbox.  This tool will not modify the design itself.

 

 

 

Workspace

 

With the View tool, mouse actions can be used to modify what part of the document is visible in the workspace.  As indicated in the following table, these actions are possible in all tools.

 

 

Mouse Action

Description

Drag left mouse button

Pans the workspace view.

Drag right mouse button

Pans the workspace view, just like left-dragging does.  This will work regardless of the selected tool, so panning is possible without switching to this tool.

Turn mouse wheel

Zooms the workspace view.  This will work regardless of the selected tool.

 

 

 

View Section

 

The options in this section modify what part of the document is visible in the workspace, as well as toggling mouse crosshairs.

 

 

Option

Description

Percent drop-down

Specifies the workspace zoom ratio.  At 100% a rendered preview pixel will occupy one screen pixel.  At 200% a rendered preview pixel will occupy four screen pixels (double width and height).

Zoom In

Click this button to zoom the view inwards.

Zoom Out

Click to zoom the view outwards.

100%

This button sets the zoom ratio to its default value of 100%.

Center

Click to center the view around the document.

Crosshairs

Click to toggle faint crosshairs around the mouse.  These crosshairs make it easier to visually align design elements.

 

 

 

Preview Section

 

The options in this section modify the preview that is created.

 

 

Option

Description

Resolution

Sets the resolution of the preview image that is rendered in the workspace.  Increasing resolution improves preview clarity, but significantly slows down refresh speeds.  This option does not affect the texture itself in any way, since the texture can still be rendered at any desired resolution independently of this setting.

Tile Opacity

Decrease this value if you would like to see a single copy of the texture in the workspace without it being tiled over a greater area.  Increasing this value allows the texture's ability to tile to be tested by repeating the texture over a larger area.

Height Map

Activating this option causes any height map constructed by the Canvas node to be displayed in the workspace instead of the texture itself.

 

 

 

Snap Grid Section

 

The options in this section control the snapping grid.  Mouse operations can be made to snap to this grid by holding down the Alt key while using other tools.

 

 

Option

Description

Density

Controls the number of grid divisions along the X and Y axes.

Opacity

Controls the visibility of the snap grid.  Setting to values above zero will make the snap grid visible.

Regular

Clicking this button creates a traditional grid with lines that run horizontally and vertically.

Isometric

Clicking this button causes the lines of the snap gird to be diagonal.  With this option active, making the Y component of the Density option larger than its X component will result in an isometric drawing grid.

 

 

 

Design Plan Section

 

The buttons in this section allow you to work with a design plan, an image which will not appear in the final texture but provides a template for drawing.  See Using a Design Plan for more details.

 

 

Button

Description

Set

Loads an image into the workspace background that can serve as a design plan.

Hide

Temporarily hides the design plan.  Clicking this button a second time will reveal the design plan again.  This button will only appear if a design plan has been loaded.

Clear

Permanently removes any design plan that was loaded into the Canvas node by clicking the Set button.

 

 

A design plan isn't considered to be part of a texture.  For this reason, a Canvas node that uses a design plan will only reference the location on your hard drive where the design plan can be found, and won't embed the image itself into the saved GTX file.  This means that if you delete the design plan file from your hard drive or open the GTX on a different computer, then the design plan will not appear in the Canvas node.
