Subdivision surfaces modifier properties

The subdivision surfaces (SDS) modifier causes the model to be rendered with additional geometric detail in the area of the model that the camera is currently looking at. The additional detail must be created in a third-party modeling application and imported into Director along with the 3D cast member. The SDS modifier is available only for models created outside of Director. The SDS modifier should not be combined with the level of detail or toon modifier on the same model.

Use these properties to work with the SDS modifier:

Property | Access | Description | Default
--- | --- | --- | ---
`whichModel``.sds.enabled` | Get and set | Enables/disables subdivision surfaces modifier functionality. | `TRUE (1)`
`whichModel``.sds.subdivision` | Get and set | The following are the possible values: `#uniform`: mesh is uniformly scaled up in detail, with each face subdivided the same number of times `#adaptive`: additional detail is added only when there are major orientation changes and only to those areas of the mesh that are currently visible | `#uniform`
`whichModel``.sds.depth` | Get and set | Maximum recursion depth, with a range of 0 to 5, to which the subdivision surfaces modifier is applied. At a value of `0`, no change occurs. | `1`
`whichModel``.sds.tension` | Get and set | Percentage of matching between modified and original surfaces. | `65`
`whichModel``.sds.error` | Get and set | Percentage of error tolerance. This property applies only if sds.subdivision equals `#adaptive`. | `0.0`
