What does the option "Is Looped" and "Loop Key Offset" in the particle emitter do and how does it work?

Hello,

I’m currently playing around with some particle effects and I came across these options when making a constant curve.
The options are called “Is Looping” which is a checkbox and “Loop Key Offset”.

I tried playing with them a bit but can’t figure out how they work or what exactly they do. When i check “Is Looped” with Offset on 0 my effect plays once and then goes back to the starting size. When I put offset to anything besides 0 it plays once and then stays at the max size.

I tried looking around but can’t really find much information about it.

Well, I cant figure it out also but for me it does not work at any settings :frowning:
