Generated UVs

Properties

Reference

Mode:All Modes Panel:Properties editor ‣ 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 View, 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.

Use UV for Mapping

Use UV values as generated texture coordinates. Note that, this is only for curve 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 View, 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.

ちなみに

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