Random animations occur randomly every 10-30 seconds (by default if I remember correctly) providing the character/npc has not been issued any destinations, isn't walking, isn't talking, or isn't playing any manually started animations.
Idle animations are supposed to go in "standing animations".
Random animations are for things such as the character blinking or scratching their head, or shuffling around on their feet, etc.
Yeah, thats exactly what I thinking.
Idle is for me animation like blinking eyes.
Do you know where I can change that time?
