Hey Robin,
Line of action currently doesn’t support what you’re asking for. You’d need to build a custom node setup and pipe it into excitation to do this.
On the topic of gravity, often models are created as if gravity is already “on” meaning that when you start to simulate you get the solver gravity effectively giving you a “double gravity” if that makes sense. If you feel like this is something you wanted to approach, you could build your setup, mulitply the solver gravity by -1 and simulate a few frames. Duplicate the muscle models in this pose and rebuild your Ziva set up on the duplicated models. You’d need to do this for the fat/skin as well, which will change the default skin model.
Hope that helps!
