# Software 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 Software 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 field
  Displays the level of rounding off, or softening of the spikes that result from colour values in the image that vary from pixel to pixel in the displacement map. Editable.

  Softness rounds the edges of the displacement. The larger the softness, the smoother the displacement. Softness also affects rendering; the larger the softness, the longer it takes to render.

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.

Offset field
  Displays the offset to the displacement of X and Y. 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.

## 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.
