Make sure that the texture mapped shader is assigned to the appropriate surface, and that this surface is the only active
object in the modeling window.
Click the 2D mapping icon in the bottom right corner of the texture swatch in the Multi-lister.
Use the Transform tools in the Texture Placement window to position and orient the texture relative to the surface. The texture’s Surface Placement and Label Mapping parameters are automatically updated when you use the Transform tools.
Close the Texture Placement window, either by clicking the 2D mapping icon in the texture swatch in the Multi-lister, or by clicking the close box in the top left corner of the Texture Placement window.
