The source node which contains the Maya scene file.
The format of the output MI file.
Export Exact Hierarchy
Tries to preserve the DAG hierarchy during processing. This produces additional
mental ray instgroup entities. There are certain unresolved material inheritance
issues in this mode, but it works well in the general case. Deeply nested DAG
hierarchies may be translated much faster compared to the standard Maya iterator
mode that always flattens the DAG.
Export Full DAG Path
Uses the full DAG path names instead of the shortest possible name for mental ray
scene entities. This is not required to generate a valid scene, but ensures
reproducible names even if DAG entity names are reused in Maya. On the other hand,
with deeply nested DAG hierarchy names, you may exceed the maximum supported name
length in mental ray.
Export Textures First
Collects all file texture references in the scene first. This ensures that missing
texture files are reported early in the process, but may slow down scene processing
depending on the number of file textures being used. It may also write out textures
references that are never used in the shading graph, because it doesn't perform a
complete scene graph traversal for performance reasons.
Export Post Effects
Lets you export post effects. This will create lots of maya garbage in your camera
and shader scenes. Probably best to leave this off unless you specifically need this
functionality.
Export Assigned Only
This option ignores objects without materials during translation so that they are
not part of the final rendered scene.
Export Visible Only
This option ignores non-animated invisible scene entities during translation so
that they are not part of the final rendered scene. This option is on by default.
Optimize Anim Detection
When this option is turned on, the processing of non-animated geometry is
significantly optimized because mental ray for Maya detects animated nodes prior to
processing the scene. This is especially useful for scenes that contain many static
objects and only a few simply animated objects.
Use Default Light
Should the default light be turned on. By default this is off.
Export Set
The name of the Maya Set used to select the DAG nodes to export from the Maya
scene. If unset, then the entire scene will be exported.
Export Children
Whether to additionally export all child DAGs of the nodes selected for export.
Export Materials
Whether to additionally export all materials associated with the nodes selected
for export.
Export Connections
Whether to additionally export shading nodes which are connected to (driving) the
nodes selected for export.
Pre Export MEL
The source node which contains the MEL script to evaluate before exporting begins.
Post Export MEL
The source node which contains the MEL script to evaluate after exporting ends.
