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.
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.
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.
Diffuse Mapping
Use a diffuse map to define the diffuse reflection and main colour of a surface, 3D model, or 3D text. Since
the diffuse map and its axis are parented by the surface or geometry node, animating the parent’s axis also
animates the diffuse map, which has the effect of keeping the map properly in place on the model. A diffuse
map uses the specular highlight, diffuse colour, and shine set by its parent.
When adding a diffuse map to a shaded surface, the diffuse is used when generating the shadow. The diffuse
is only used to apply the colour to the shadow, so effects such as surface displacement still reference the
media associated with the surface. If a node has an applied diffuse map, it is the matte setting of the diffuse
map that controls whether the object will be included in the various output mattes (scene matte, blend
matte, for example).
To add a diffuse map:
1 In the schematic, select the surface, 3D model, or 3D text to which you want to apply the diffuse map.
2 Click Media.
