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

Displacement Type box

Select whether to use hardware (GPU) or software (CPU) displacement mapping.

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.

Wrap Wrap mapping completely envelops the 3D model with the texture map according to the object’s texture coordinates. To use this option, you must import a model that has its own texture coordinates. When using Wrap mode, you can also apply UV mapping settings from the Geometry menu.

Plane Planar mapping applies the map without distorting the front plane of the 3D model, similar to a movie projector casting an image onto a screen. All 3D coordinates of the geometry are mapped to this plane to generate the texture values. Planar mapping positions the lower-left corner of the map on the 3D model’s axis. When you apply planar mapping, any surfaces on the 3D model perpendicular to the front plane cause the pixels at the edge of the texture to project along the “sides” of the object.

Tri-Planar Similar to plane mapping, except that it applies the map from all 3 axes, blending using the normals orientation with respect to the axis of projection.

Perspective Perspective mapping is similar to planar mapping, except that it performs a perspective transformation of the map based on the selected camera’s field of view (FOV). When you select Perspective as the mapping type, the Perspective Camera box becomes active, allowing you to specify the active camera. The FOV of the camera has an impact on the resulting effect of any transform applied to the parent axis of the texture. On stereo cameras, the interaxial distance between left and right cameras also has an effect on the resulting perspective transform.

Tri-Perspective Similar to perspective mapping, except that it applies the map from all 3 axes, blending using the normals orientation with respect to the axis of perspective.

Projection The texture behaves as if it is projected by the selected camera. Projection mapping is useful as an alternative to projecting textures using the Projector node, especially when it is necessary to project while preserving a specific camera POV.

Camera box

Specify which camera's FOV to take into account when using perspective or projection mapping.

Camera field

Displays the active perspective or projection camera number.

Stereo Camera Projection box

Select whether to use the centre, left, or right camera from a stereo camera rig when projection mapping.

Filter box

Select the type of filtering to apply to the map.

Camera Type box

Select the camera type visibility for the map.
