hello everyone:
in the vtourskin.xml has this code as below:
```
<action name="skin_view_ball">
set(view.stereographic, false);
set(view.fovmax, 180);
tween(view.architectural, 0.0, distance(1.0,0.5));
tween(view.pannini, 0.0, distance(1.0,0.5));
tween(view.distortionfovlink, 1.0, distance(1.0,0.5));
tween(view.distortion, 3.0, distance(1.0,0.8));
tween(view.fov, 180, distance(150,0.8));
tween(view.vlookat, 0, distance(100,0.8));
</action>
```
but it is not workds when I use krpano.call('skin_view_ball()') , I think the problem is in view.vlookatrange == 180 ,how can i relove it ?
