You can set and retrieve data for multiple Effectors at the same time using a data set, introduced under Workflows for Setting and Retrieving Data.
The exact procedures for doing so, including the data description structure you must use for your data set, differ depending on whether you want to set and retrieve each Effector’s translation, orientation and scaling data using separate number arrays or using transform matrices. See either Setting and Retrieving Effector Data Using Separate TQS Values, or Setting and Retrieving Effector Data Using Matrices.
