Which Custom Properties were stored between different events?

[tyFlow]

I don't understand your first question...custom properties are stored in particles, not events. Once a particle is assigned a custom property it will travel with it to any/all events.

Vectors are just groups of 3 floats, representing values for x/y/z axes. A float is a single value like :

Code:

19.023

whereas a vector is 3 float values grouped together, usually used to represent a direction or position in 3d space:

Code:

[19.023, -1.93, 910]

I'm not sure why TM is the usual abbreviation to be honest...probably either TransforMation or Transformation Matrix
