Texture Maps

All texture maps are assumed to be square. If the image used is not square it will be stretched/compacted into a square texture map, possibly deforming the texture.
The size of all texture maps is equal to one unit of the currently defined Space Unit in the Model space. For example if the Space Unit is set to inches the all texture maps are 1in. by 1in. If the Space Unit is in millimeters then the texture map is 1mm. by 1mm. The resulting texture can then be modified by scaling.
There are several parameters that control how texture maps affect a material.

Browse

The browse button opens a File Open dialog from which you can browse for a texture map file (supported file formats are JPEG, GIF, PNG, BMP).

Channel

Offset U

This offsets the texture map horizontally. Each unit of offset equals 1 Space Unit (mm, in. etc.) as specified in the Model space.

Offset by 0.5 Horizontally

Offset V

This offsets the texture map vertically. Each unit of offset equals 1 Space Unit (mm, in. etc.) as specified in the Model space.

Offset by 0.5 Vertically.

Scale U

This scales the texture map horizontally. The value specifies the number of time the texture map will fit in 1 Space Unit (mm, in. etc.) as specified in the Model space. For example if the Space Unit is 1 inch, and if the scale is set to 2, the texture map will repeat 2 times within 1 inch. If the scale were changed to 0.2 it would take 5 inches to display the entire texture map.

Scaled by 2 Horizontally.

Scale V

This scales the texture map vertically. The value specifies the number of time the texture map will fit in 1 Space Unit (mm, in. etc.) as specified in the Model space. For example if the Space Unit is 1 inch, and if the scale is set to 2, the texture map will repeat 2 times within 1 inch. If the scale were changed to 0.2 it would take 5 inches to display the entire texture map.

Scaled by 4 Vertically.

Rotation

This Rotates the texture map by the number of degrees specified.
