For more information on the displacement material, see Maya materials.
Find this material in the Hypershade Create tab.
Connect a one-dimensional (height) displacement map to this attribute to create surface relief for your model. The default displacement value is 0.
Connect a three-dimensional (x, y, z) displacement map to this attribute to create surface relief for your model.
Tweak this attribute to adjust the effect of your vector displacement map, for example, to make it more or less pronounced.
Floating Point Absolute: Select Floating Point Absolute if your vector displacement map uses a floating point encoding format such as .exr or 32-bit floating point .tif.
Signed Encoding: Select Signed Encoding when your vector displacement map is defined by a fixed point encoding format such as .jpg or .bmp.
If you are using Mudbox to create your vector displacement map, you must use the .exr/.tif formats and select Floating Point Absolute as your Vector Encoding.
Indicates the vector basis for your vector displacement map.
World: vector displacement in x, y, z world space co-ordinates.
Object: vector displacement in x, y, z object space co-ordinates.
Tangent:
Use this attribute to connect a map that provides a tangent for your surface. This attribute is only applicable if you select Tangent as your vector space.
