* use a double vision to make a map
* Author: Yu snow wind

* usage: add the remote map and the occlusion map in the parallax file, and use it directly when the map is used.
* the naming rule of the sion 1 block diagram is the name of the remote map file +'_2'
* Note: since MV takes a long view of the map as a function (the name of the remote picture begins with '!', it is used as a map).
* so, this script only adds the part of the occlusion map.
* Note: when the name of the remote view file does not begin with '!', it is used as well as the usual vision function, and does not do the map processing.
* Note: if the vision map, and does not need the occlusion map, the vision picture name to '$' at the beginning.
