The Cover and Size radio buttons set the size of a surface texture in one of two ways: Cover reflects the percentage of the object coverage, while Size reflects the coverage of the texture as a specific size.
You can also specify the number of times a map will be repeated. Enter numeric values in the Reps field. Infinite (INF) repeats the map infinitely across the object until the edge is reached
A special Fit Texture button is provided on the Commands Tab of the Extensions palette that centers the texture on the object with 100 percent coverage. This is the default texture orientation. This button allows you to return to the default orientation if you are not happy with your positioning.
