XGen Preview Settings

Start Percent

Controls the percentage of primitive positions that are calculated and discarded before generating primitives for preview. Use this if primitives are being created in a specific order (not randomly).

Percent

Controls the percentage of generated primitives you want to appear in the preview. Turning this down speeds the refresh while providing a good representation of the final render. Ranges from 100 to Start Percent.

Limit

Sets the maximum number of primitive generated in the preview.

Use this option to reduce the number of primitives generated on large polygon objects to avoid Maya performance issues.

Only primitives in the view

Previews primitives in the camera view (frustum). This does not affect the final render.

View Margin

Controls how far (in degrees) a primitive can be outside the view and still be included in the preview. Use this with Only primitives in the view.

Draw

Patch Names

Displays patch names in the view.

Important: Select the geometry or description before activating Patch Names or they do not display.

Face IDs

Displays Face IDs in the view. You can use this to determine if the XGen face IDs of the mesh are different from the Maya face IDs. This can be the case when a non-quad only mesh is being used. XGen will subdivide the non-quad face into quads and assign face IDs to those sub-faces.

Important: Select the geometry or Description before activating Face IDs or they do not display.

Primitive IDs

Displays an ID number for each primitive in the preview. Primitives are numbered per-face.

Vertices

Displays the vertices on the primitives.

The vertices displayed are not always those of the computed primitive. Turn on Poly for a more accurate display of vertices.

Poly

Displays the primitives as simple polygons, not smoothed.

Culled

Displays culled primitives in the preview.

Unit Cube

Displays a unit cube around the contents of the archive files. This applies to Archive primitives only.

Primitive IDs At

Controls the location along the primitive where IDs display. 0 is the base of the primitive, and 1 is the tip.

This is only enabled when Primitive IDs is turned on.

Primitive Color

Sets the color used to display the primitive. When set to 0.0, the primitive displays with its default shader color.

Guide Color

Sets the color used to display guides.

Spline Segments

Smooths previewed splines by increasing the number of linear segments drawn for each CV in the spline. Higher values can slow the preview generation. You can use Spline Segment as a sampling value for splines when generating a preview.
