UVs & Texture Space

UV Maps

In the Mesh tab the UV maps panel contains a List view that lists the UV maps created for this mesh. The selected map is displayed in the UV Editor.

Active Render: Click the camera icon to enable that UV texture for rendering. If no other map is explicitly specified.
Add +: Clicking the Add button duplicates the selected UV map.

Note that each texture can be mapped to a specific UV layout.

Texture Space

Reference

Mode: All Modes
Panel: Properties ‣ Object Data ‣ Texture Space

These are settings of the Texture Space used by generated texture mapping. The visualization of the texture space can be activated in the Viewport Display.

Auto Texture Space

Adjusts the active object’s texture space automatically when transforming the object.

Location, Size: If the texture space is not calculated automatically then you can define the location and size of the texture space relative to the base object. These can also be adjusted from the 3D Viewport, see Editing for more information.

Texture Mesh: Use another mesh for texture indices, the vertex of the two objects must be perfectly aligned. Otherwise the UV map will be distorted. Note that, this is only for mesh objects.
Match Texture Space: Modifies the Location and Size to match the objects bounding box. This disables Auto Texture Space. Note that, this is only for curve objects.

Editing

Reference

Mode: Object Mode and Edit Mode
Menu: Object ‣ Transform ‣ Scale/Move Texture Space

To modify the texture space from the 3D Viewport, enable Edit Texture Space while transforming an object.

Accessing

The automatically calculated UV map can be accessed by an object’s material through the Generated output of the Texture Coordinate Node. This output can then be used to map any texture onto an object.

Vihje

Generated texture spaces do not have rotation support, to overcome this, a Mapping Node can be used to rotate the UV map.
