Swimming Textures

Swimming textures are an undesirable effect that can occur when you animate an object that has a 3D texture applied to it; the animated object moves, but the assigned texture stays in the same place. This happens because the 3D texture is assigned to the object based on the geometry's world position, not the UV coordinates. To avoid swimming textures, you can parent the placement node to the object or set the texture to local. If the object deforms, the only way to fix the problem is to convert the 3D texture to a file-based texture so that it uses UVs (which deform and move with the object).

To convert a 3D texture to a file texture:

1.	Create a NURBS primitive sphere.
2.	Open the Hypershade, create a new blinn material, and assign it to the sphere.
3.	Double-click the blinn to open the Attribute Editor.
4.	Click the Map button for Color.
5.	Select the 3D texture wood.
6.	In the modeling window, select the sphere; in the Hypershade, -select the blinn.
7.	From the Edit menu in the Hypershade, select Convert to File Texture. An image file is generated, and the new blinn is assigned to the sphere.
