Okay, I made a similar test level in A7 , giving this action to 3 different models

2 sphere and a woman model.Code:

---

action phys_obj
{var earthgravity[3] = 1,1, -386;


	ph_setgravity(earthgravity);
	phent_settype(my,PH_RIGID,ph_sphere); 
	phent_setmass(my,3,ph_sphere);
	phent_setfriction(my,30);
	phent_setelasticity(my,50,10);
		phent_setdamping(my,90,90);
};
} 

---

the spheroids mdl remain immoble, both.
The woman mannequin roll over then stops.
