A new free DAZ Studio script set for Genesis 3 Female, just released. It appears that you select the joint of the character you want to display and run the script. “Joints whose Limit setting has been cancelled are displayed in green”.
So presumably, when you’ve applied a character pose and selected “Turn limits off”, this script visually identifies where exactly the character’s joints are pushing beyond reality. It looks a useful timesaver for character and pose makers, and testers, and may also help artists who have a complex animation scene where something has gone awry but they’re not sure what or where.
There’s also a script to hide multiple body joints at once, presumably similar to how you can quickly hide multiple parts with Scene Toy in Poser but done automatically. It looks like you can use the script to hide say… the Left Collar, and then all the connected bits of the left arm and hand will also be automatically hidden along with it.
