Using the Texture Support Object
Texture supports let you control the way the texture is projected on the object. For example, if you choose a spherical object and a spherical mapping type, the texture support wraps around the sphere and defines a spherical shape from which the texture is projected.
You can also perform transformations on texture supports that alter the way a texture’s image is projected onto an object. The texture is constrained to the support so that when you rotate or scale the support, it also affects the texture. For example, if you enlarge the texture support, the texture image is also enlarged.
The texture’s center of projection (calculated according to the center of the texture support) displays automatically and can be translated anywhere within the texture support. This is a way to further distort the texture’s image on the object.
The center of the texture support is calculated according to the center of the object’s bounding box.
To display the texture support
1. Select the object whose method of texture projection you want to change.
2. If the support object still isn’t visible, select the Show > Texture Controls option from a viewport’s camera menu .
Scaling, Rotating, and Translating the Texture Support Object
You can interactively scale (x key), rotate (c key), or translate (v key) a texture-support object—hence the texture itself—directly in a 3D view using the Scale, Rotate, and Translate commands in the Transform panel. You can also animate these transformations with keyframes. You can also align textures to one or more selected polygons of the object to which the texture is applied.
For more information on how to animate a texture support object, see Manipulating Textures.
Copying and Connecting Texture Supports
You can duplicate a texture support object as you would any element in a 3D view. You can then connect the duplicate texture support to an object.
|
You can also duplicate a texture support automatically when you duplicate the textured object whose texture projection it drives. |
To connect a texture support to an object
1. In any 3D view, select the object you wish to connect to a texture support.
2. Choose Get > Property > Texture Projection > Connect to Support.
3. Enter a name for the new texture projection in the dialog box.
4. From any 3D view, select a texture support object to attach to the object.
|
An object that you attach to a copy of a texture support is not automatically constrained to the support. |
Constraining a Texture Support to a Bounding Box
Choose the Get > Property > Texture Projection > Constrain Support to Bounding Box command to constrain any object to an existing texture projection that has been applied to a group, branch, or tree hierarchy.
|
This command cannot be applied to a multi-selection. |
Swapping the U and V Directions
By selecting the Swap UV option in a texture support property editor, you can exchange the U and V directions of the texture coordinates so that the texture rotates and flips. The Swap UV option is in the Texture Projection property editor.
To swap the U and V directions
1. Select the texture support.
2. Do one of the following:
- Click the Selection button in the Select panel. From the explorer that appears, select the Texture Support Property (P symbol).
or
- Press Alt+Enter to open the general property editor for the texture projection.
3. In the texture support’s property editor, select the Swap UV option.
Removing a Texture Support Object
To remove a texture support object
• Select it and press Delete. Any textures assigned to the deleted texture support are also removed and deleted.
