Which Custom Properties were stored between different events?

[Alexx31]

Hello everybody,



I'm working with Custom Properties:



1.)
I remember that some of them were not available in a new event?

Vector Data / TM Data / Float Data



(I'm tweaking a scene with custom properties and can't say, if some properties do not work because not available or because I have to change something at the flow.

Because it's not possible to read what is stored in a custom property)

2.)
What is the difference between Vector Data and Float Data?
I mean I know the definitions of vector (can store more than just one float) and float.

I can choose for SCALE for example
Custom Vector Data > Scale
or
Custom Float Data > Scale magnitude

Does the scale magnitude just store one average value for X, Y and Z?

3.)
TM-Data are of course Transformation data.
But why is the abbrevation "TM"? What is the "M"?



Thanks
