The Element Attach operator allows you to combine neighboring particle meshes together.
After a successful attach operation between particles is completed, only the resulting particle (with the newly combined shape mesh) will remain – the rest will be deleted.
Max/element: controls the maximum number of neighbor particles that can be attached to a particle.
Max dist: the maximum distance between two particles in order for them to be attach candidates.
Iterations: the number of overall attach iterations to perform. This will recursively attach groups of neighboring particles together.
Overlapping only: controls whether convex hulls of particles will be computed, in order to determine if particles physically overlap. Only overlapping particles will be attached to each other.
New only: when enabled, only particles that are new in the event will be attach candidates.
Parallel only: when enabled, only particles that are parallel to each other in space will be attached.
Matching MatID only: when enabled, only particles with matching material IDs will be attach candidates for each other.
Center pivots: moves each combine mesh’s particle offset to its center.
Enable clustering: controls whether attach candidates will be determined by cluster values.
Channel: the particle data channel to get cluster values from.
Cluster if equal: attach candidates must have equal cluster values.
Cluster if equal: attach candidates must have unequal cluster values.
