The particleMatrix channel could be used to store either a matrix3 value or a set of 4 Point3 values, or 12 Float values. This makes it very versatile when a large number of values have to be stored. As noted in the matrix3 chapter, you cannot directly assign values to sub-elements of a matrix3 value. To write a Point3 or Float value to the particleMatrix channel, first store the particleMatrix value in a user variable, assign the Point3 to the respective row of the matrix or the Float value to the.x,.y or.z element of the Point3 and then assign the variable back to the particleMatrix channel.
