Current Limitations
The following list outlines the current limitations for FBX import:
■ Password protected FBX files cannot be imported in Composite.
■ You cannot selectively import assets from the FBX file; Composite imports
everything it recognizes.
■ By default, the geometry import tool imports all meshes of the scene into
a single layer. However, you can select which geometry to import.
■ The geometry tool imports the global transformation of the geometry in
Composite; its bakes the transformation of its parent hierarchy into the
mesh.
■ Composite doesn't support multiple UV coordinate on a vertex,; it only
imports the first (index 0) diffuse set of coordinates.
■ FBX animation curves are recalculated into a Composite animation with
one keyframe at each frame.
■ If the FBX scene contains more than one camera, the format of the resulting
composition (and the Reaction node) is based on the render settings of
the default camera.
■ The camera image plane distance, its size on aperture, the camera focal
length and the horizontal scale are all animatable values in FBX, but the
transformation of the imported plane layer in Composite is not animated.
■ The image plane offset values which controls how much the center of the
image plane is offset from the centre of the viewing frustum of the camera
are not supported by the FBX import.
■ The camera image plane layer cannot be created correctly if Composite
doesn't have access or cannot import the asociated image files, because it
needs to know the image resolution to scale the plane layer in Reaction.
Also, the Image Import tool cannot store the path of an image sequence
that doesn't exist.
■ Parameters that control the amount of the source image that is used in
the camera image plane are not supported.
■ Target cameras are not supported.
■ Once the Maya camera image plane is imported in Composite, it is no
longer a “camera” image plane (one that automatically rescales itself to fit
