It converts objects, splines and particles into voxel volumes combinable with Boolean operations — complex organic merges without topology headaches, typically meshed by the Volume Mesher. This Generator object can be used to create Voxel objects from all sorts of Cinema 4D [objects](https://help.maxon.net/c4d/en-us/Content/html/OVOLUMEBUILDER-ID_OBJECTPROPERTIES.html.md). These objects are generally made Child objects of Volume generators, which will in turn appear in the Object List (Object tab). Make sure that the polygon objects are closed. Simple objects can also be dragged into this Object List, regardless of their location in the hierarchy (you might have to hide these objects in order to properly display Boolean operations). ![Image: 041430.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/041430.jpg)\ Multiple objects are combined using a Boolean operation to create a complex single object.

The Volume Builder can be made editable by pressing the `c` key, which will create a [Volume Object](https://help.maxon.net/c4d/en-us/Content/html/OVOLUME.html.md). Several Volume Builders can be combined in a [Volume Set](https://help.maxon.net/c4d/en-us/Content/html/OVOLUMESET.html.md) using the [Connect Objects + Delete](https://help.maxon.net/c4d/en-us/Content/html/40756.html.md) command.
