So I currently have this weird bug where the relative scaling inside the scale trigger doesn't work.
I also crashed my entire device after messing with the scale triggers, I don't know if that's the cause but I guess I'll put it there ¯_(ツ)_/¯
But yeah, look at the scale triggers in the video, they have the relative scale enabled, but when it scales the object (the yellow bar), it acts like it's disabled.
