Toggles automatic culling on and off (hiding or removing) of primitives. This controls culling on backfaces and outside the view, but has no effect on manually-culled primitives.
Turn on to see (in your preview) the primitives being culled. Culled primitives are not rendered. In the preview, culled primitives display in red and purple.
Turn on to cull primitives that are created on surfaces that face away from the camera. These are usually not visible in the final frame, and you can save rendering time by culling them.
Controls how far the surface must be turned away from the camera, in degrees, before culling occurs. You can increase this to ensure that primitives are still shown on the silhouette of the surface.
Turn on to cull primitives that are outside the camera view (the frustum). You can save rendering time by culling them. You can render primitives outside the view in certain cases, such as when they are visible in reflections.
Sets a buffer, in degrees, outside the camera frustum that primitives can generate without being culled. Use this to ensure primitives generate before appearing in the frustum of an animated camera.
This expression is evaluated for each primitive that XGen generates. If the expression returns any value other than 0, that primitive is culled.
Select primitives with the Select Tool, then click Cull Selected Primitives to cull (remove or hide) them.
Select culled primitives, (you can display them with Display Culled Primitives above) then click Uncull to bring them back.
