This attribute currently has no effect in Maya.

outSubdiv (o)	subdivisionSurface	NULL
The output subdivision surface.
worldSubdiv (ws)	subdivisionSurface	NULL
The output subdivision surface in world space.
edgeCrease (ecr)	subdivEdgeCrease	NULL
Edge creases
textureCoord (uvs)	subdivTextCoord	NULL
Texture Coordinates
faceUVIds (fuv)	subdivFaceUVIds	NULL
Face corner UV Ids. Explicit UVs on subdiv surfaces are stored on a per-face per-vertex basis. This attribute is used to specify the UV ids on a per-face per-vertex for each UV set that exists on the surface. The values on this attribute are to be used in conjunction with the UVSetPoints attribute defined in the parent controlPointShape class, since that attribute holds on to the uv values corresponding to these ids.
normalsDisplayScale (ndf)	double	1.0
Specifies the scaling factor for the surface normal display.
format (f)	enum	1
Format: 0 - Uniform, 1 - Adaptive (Leaf Level)
depth (d)	integer	2
The depth at which constant-depth tessellates the surface
sampleCount (sc)	integer	4
The number of samples per face
displayLevel (dl)	enum	0
The level at which components (vertices, edges, faces...) will be displayed. Valid values are 0=Base through 13=Finest.
displayFilter (dfl)	enum	0
Determines whether diplay includes components "edited" or "visited" at the current display level. Valid values are 0=Edited, 1=Visited, or 2=All.
baseFaceCount (bfc)	integer	0
The number of base mesh faces
levelOneFaceCount (ofc)	integer	0
The number of faces at level 1
scalingHierarchy (sh)	enum	1
Controls how scaling of coarser vertices affects finer ones. When set to "Propagate", scaling applied to coarser vertices is propagated to those at finer levels of the hierarchy. This has the effect of making hierarchically-added geometric features scale with the surface as coarser vertices are manipulated. When this attribute is set to "Ignore", scaling applied to coarser vertices is ignored at finer levels of the hierarchy. This has the effect of making hierarchically-added geometric features maintain their size as the rest of the surface is manipulated. Note that this attribute has no effect on scaling applied to the entire object via transforms anywhere above it in the DAG, only to vertices of the surface via component manipulation or (indirectly) via deformations applied to vertices.
mentalRayControls (mrc)	compound	n/a
This is a root of following mental ray attributes.
miOverrideCaustics (oca) bool false Enable caustic settings override for this shape. If this parameter is set, the following caustics settings will override the renddr global settings for this shape node.
miCausticAccuracy (caa) short 64 Caustic accuracy for this shape if miOverrideCaustics is on.
miCausticRadius (car) float 0 Caustic radius for this shape if miOverrideCaustics is on.
miOverrideGlobalIllumination (ogi) bool false Enable global illumination settings override for this shape. If this parameter is set, the following global illumination settings will override the renddr global settings for this shape node.
miGlobillumAccuracy (gia) short 64 Global illumination accuracy for this shape if miOverrideGlobalIllumination is on.
miGlobillumRadius (gir) float 0 Global illumination radius for this shape if miOverrideGlobalIllumination is on.
miOverrideFinalGather (ofg) bool false Enable final gather settings override for this shape. If this parameter is set, the following final gather settings will override the renddr global settings for this shape node.
miFinalGatherRays (fry) integer 1000 Final gather rays for this shape if miOverrideFinalGather is on.
miFinalGatherMinRadius (fmn) float 0 Final gather min radius for this shape if miOverrideFinalGather is on.
miFinalGatherMaxRadius (fmx) float 0 Final gather max radius for this shape if miOverrideFinalGather is on.
miFinalGatherFilter (ffi) short 1 Final gather filter for this shape if miOverrideFinalGather is on.
miFinalGatherView (fgv) bool false Final gather view flag for this shape if miOverrideFinalGather is on.
miOverrideSamples (oos) bool false Override global object sample settings. In addition to global sample settings mental ray supports per-object sample settings. The global mental ray default for all objects in the scene can be set by minObjectSamples and maxObjectSamples on the mental ray options node (miDefaultOptions). Similar attributes on individual shape nodes miMinSamples and miMaxSamples are overriding the global default, within global samples range.
miMinSamples (mins) short 0 Specifies min sample settings for the shape. For all pixels that touch this object, at least pow(2, miMinSamples) samples are taken. miMinSamples lower than the global min samples is ignored.
miMaxSamples (maxs) short 2 Specifies max sample settings for the shape. For all pixels that touch this object, at most pow(2, miMaxSamples) samples are taken. miMaxSamples higher than the global max samples is ignored.
miFinalGatherCast (fgc) bool true The object casts final gather rays if miFinalGatherCast is on, which means that the object participates in final gather.
miFinalGatherReceive (fge) bool true The object receives final gather rays if miFinalGatherReceive is on, which means that the object is not affected by final gathering.
miTransparencyCast (tpc) bool true The object casts transparent rays if miTransparencyCast is on. thus shown through transparent object if ray depth has not been reached the limit.
miTransparencyReceive (tpr) bool true The object receives transparent rays if miTransparencyReceive is on.
miReflectionReceive (rflr) bool true The object receives reflection rays if miReflectionReceive is on. This flag controls reflection of other objects on this object. If disabled, this object will not show any reflection, as if the surface is not reflective. The casting behaviour is ruled by visibleInReflections flag, which controls reflection of this object on other objects. Disabling visibleInReflections will make this object disappera from reflection.
miRefractionReceive (rfrr) bool true The object receives refraction rays if miRefractionReceive is on. This flag contols refraction of other objects through this object. Disabling this value will make this object non-refractive. The casting behaviour is ruled by visibleInRefractions flag, which controls refraction of this object showing through other objects. Disabling visibleInRefractions will make this object disappear from refraction.
miProxyFile (mof) string NULL When rendering with mental ray, replace this object with the mental ray assembly file referenced by this attribute.
miUpdateProxyBoundingBoxMode (upbm) enum 0 Controls how the bounding box attributes for the render proxy are updated when the render proxy file changes. Choices are: Proxy and geometry bounding boxes: both the proxy bounding box and geometry are updated Proxy bounding box only: only the proxy bounding box is updated, the geometry remains the same in the scene Geometry bounding box only: only the geometry changes in the scene, the proxy bounding box attributes are untouched None: Neither proxy bounding box or geometry is changed
miProxyBoundingBox (mbb) compound n/a Root for the bounding box attribute of the proxy object miProxyBoundingBoxMin (mbmn) double3 Minimum value of bounding box for proxy object miProxyBoundingBoxMinX (mbnx) double 0.0 X value of minimum bounding box for proxy object miProxyBoundingBoxMinY (mbny) double 0.0 Y value of minimum bounding box for proxy object miProxyBoundingBoxMinZ (mbnz) double 0.0 Z value of minimum bounding box for proxy object miProxyBoundingBoxMax (mbmx) double3 Maximum value of bounding box for proxy object miProxyBoundingBoxMaxX (mbxx) double 0.0 X value of maximum bounding box for proxy object miProxyBoundingBoxMaxY (mbxy) double 0.0 Y value of maximum bounding box for proxy object miProxyBoundingBoxMaxZ (mbxz) double 0.0 Z value of maximum bounding box for proxy object
