| 475 | With several groups of particles (see [#number_of_particle_groups number_of_particle_groups]), each group can be assigned a different value. If the number of values given for '''radius''' is less than the number of groups defined by [#number_of_particle_groups number_of_particle_groups]), then the last assigned value is used for all remaining groups. This means that by default the particle radius for all groups will be ''0.0.'' |
