This can initially be non-existent if the Volume was created outside of Cinema 4D (e.g., using a Volume Builder that was made editable). When the scene is saved, a still non-existent \*.vdb file will be created and saved with the scene file in a folder named vol. This relative path will be set automatically. The file path can be changed at any time to create a new link. You can create a new relative path by simply entering a new file name (which will be saved/ found in a vol folder where the scene is saved). You can define an absolute path by clicking on the button at the right of the path and selecting the new path. ### Save Parameter ID: `ID_VOLUME_SAVE` If you create new Volume objects in the scene that do not yet exist externally, they can be saved with this button. ### Reload Parameter ID: `ID_VOLUME_RELOAD` Since volumes stored in external files can change, you can always load the current volume by clicking this button. ### Info First of all, you will find the type of volume of the external, linked \*.vdb file displayed here. Cinema 4D can only evaluate **Float Signed Distance Field** and **Float Fog**. All other Volume object types are partially imported but not evaluated. Below this, the Voxel count used and the amount of memory used are displayed.
