### Remarks

Depending on [renderPickingType](/engine/6000.6/script-reference/unityeditor/renderpickingargs/renderpickingtype.md), the GameObjects in this set are expected to be either included or excluded from the picking rendering. Refer to [renderPickingType](/engine/6000.6/script-reference/unityeditor/renderpickingargs/renderpickingtype.md).

This set cannot be null, but it can be empty. Use [RenderObjectSetContains](/engine/6000.6/script-reference/unityeditor/renderpickingargs/renderobjectsetcontains.md) to query whether a GameObject is contained in the set.
