I've just uploaded a new version of the Conversive Character Studio, it is now version 18.104.22.168 with the highly-anticipated feature: Idle Levels.
How Idle Levels work currently:
You now have a list of Idle Levels attached to your character which are activated in sequence while the character is idle (not animating or speaking). Each idle level has min and max values for start delay, duration, and interval. I think this gives the creator a nice amount of control over how the character behaves when he/she isn't active.
the latest version and let me know what you think!
