Ok thanks.
c_updatehull does not set the bounding box to the actual frame..I see.
Also sets the bounding box to the size of the collision hull
So I've been here long time, what is the difference between collision hull and bound box?
c_updatehull(my,1); // same effect as c_setminmax
c_setminmax(my); //same effect as c_updatehull
vec_formin/max. // Only one that actual sets the bounding box to "the real size of the model"
