# Hardware Displacement Menu Settings

Displacement Type box
  Select whether to use hardware or software displacement mapping.
Regen button
  Enable to dynamically refresh the image as changes are made to the menu settings.

The Hardware Displacement menu is divided into two tabbed sections: Controls and Texture.

Controls Tab

Channel box
  Select a colour channel to calculate the displacement map.

Softness X field
  Displays the amount of X-axis blur applied to the map. Editable.

Softness Y field
  Displays the amount of Y-axis blur applied to the map. Editable.

Displace Direction box
  Select the direction in which a displace occurs when a displacement map is attached to a surface. Geometries parented to a displacement map always use Normal Displace as the direction.

  Select: | To Displace:
  --- | ---
  Flat Displace | In the X, Y, and Z directions.
  Normal Displace | Bilinear and bicubic surfaces according to their normals.
  Camera Displace | In the direction of the camera selected in the Displace Camera box.

Bias field
  Displays the distance between the real surface of the object and the perceptual ground (zero level) of the texture. Editable.

Attenuate field
  Displays the level of amplitude of the effect caused by the displacement map texture. Editable.

Displace Camera box
  Active only when Camera Displace is selected in the Displace Direction box. Select which camera to take into account when using camera displacement.
Displace Camera field
  Displays the active displace camera number. Non-editable.
Displacement X field
  Displays the amount of displacement in pixel units along the X axis. Editable.
Displacement Y field
  Displays the amount of displacement in pixel units along the Y axis. Editable.
Displacement Z field
  Displays the amount of displacement in pixel units along the Z axis. Editable.

Bump Normals button
  Enable to allow the map to create a normal map for enhanced lighting effects. Used only if no normal map exists for the object using the displacement texture. The availability of this setting is dependant on your graphics card.

Depth field
  Displays the amount of Z scale applied to the generated normals. Higher values attenuate the effect toward the normals of the parent surface. Editable.

Texture Tab

Repeat mode box
  Select how the map pattern is repeated on the surface.
Fit Method box
  Select a fit method option to be applied to the map.

Keep Aspect button
  Enable to preserve the aspect ratio of non-square pixels (not available for the Fill fit method).

Use Cropped Size button
  Enable to replace the map with the cropped size of the media. Disable to use the cropped media as is.

Mapping box
  Select the type of texture mapping.

Camera box
  Specify which camera's FOV to take into account when using perspective mapping.

Camera field
  Displays the active perspective camera number.

Filter box
  Select the type of filtering to apply to the map.

Camera Type box
  Select the camera type visibility for the map.
