Functional Details

It filters and reduces the number of items in the "data" component of the input field and also in any components that are position or connection dependent.
input is the field to be reduced. It must have regular connections.
factor specifies the reduction factor(s) to be used in reducing the resolution of the field.
If this parameter specifies:

Components

All components in the input are propagated to the output. Components dependent on "positions" or "connections" are filtered.
