The object type parameters for the generation of granular structures are organized and listed in three columns. In the left one define the Object Type together with its percentage and material, the center column shows a scheme of the chosen object type's parameters and in the right one you can edit the object parameters. In the bottom, find the options to choose additional object types and how the object percentage should be given.
