Group 3d Mask

3D Mask - Mask according to object id or particles group

This mask can be used with a 3D File with multiple objects in it, grouped in one mesh or with a Particles's groups.
Their function is to apply a 3D Modifier or a Field only on a specific object or a particle Group. Groups of particles can be defined through Particle Rule.

On the example below, you see the white particles emitted in the Group [1]. Theses particles have an "Increase Group" action ("Set Group" action in menu) that changes their Group to [2].
The Gravity field has a Group Selector Mask set as Single Selection on Group [2], which means that the gravity field will only have an effect on the second Group.

3 mode of selection are available:
- Single selection: only the group set in the start parameter will be affected.
- Range Selection Block: all the group between the start and End will be fully affected.
- Range Selection Progressive: the lower group will be fully masked while the higher group will be fully affected, with a gradual progression in between.
