Note that all new maps start out selected. The VMap List window, discussed later, also shows the selected map in each category. The pop-up menu in the bottom-right corner of Modeler shows the current selection for the weight, UV texture, and morph categories, and can be used to change them. There can be one selected VMap of each general category (weight, UV texture, etc.), and they can be selected in different ways. It might save you some typing time, so Modeler still places the name in the pop-up menu that appears beside the naming field when you are creating a new VMap. However, if you deselect a new VMap before using it, it will disappear from current VMap listings. Initially, they will appear in pop-up menus even if they contain no data. New VMaps are an exception to the above standard. Not all VMap pop-up menus will do this filtering, however, particularly those on plugins. Generally, the only VMaps listed in the main VMap pop-up menu are those that contain actual data in the current object. If you rename a VMap, all VMaps (for loaded objects) with the same name are renamed. There is no cross-talk between objects, except in the case of renaming.

However, editing a map in one object will not affect other objects (using the same VMap name) because the data in the map is attached to the geometry of that object. Internally, there is a single list of VMaps, which includes the maps from all the objects that are loaded. Use the Selection Info command (Info button on the bottom taskbar, or press I ) to determine what VMaps and values are assigned to individual points.Weight maps have a general range of -100% to +100%.

Thus, depending on the situation, you may be able to minimise the file size by judiciously assigning VMaps to points.īecause you can use vertex maps (VMaps) throughout LightWave, you should have a solid understanding of how they work. VMaps are extra data and will increase your object’s file size. Many LightWave commands, however, also have the ability to create VMaps. Once the map is created, you can set or edit the values in the map. VMaps are normally created using the buttons in the lower-right corner of Modeler. However, some functions that use VMaps consider these two states to be equal - usually by necessity - essentially filling the holes with zeros. Note that an assigned value of 0 is not the same as not having the VMap assigned to that point. If a point has no entry for a particular VMap, the VMap is not assigned to that point - this map will have holes in it. Weight maps are used more generally, like for bone influence however, the SubPatch weight map is used specifically for control-point tension. Endomorphs hold offset information for point position. For example, UV Maps hold texture placement information. Some VMap types are designed for special built-in functions. Like surfaces, you name your VMaps, which allows you to access them to perform certain operations. The VMap data is all stored in the object file.īasically, VMaps are to points, what surfaces are to polygons. Any point in an object can have a unique entry (value) for a particular VMap or no entry at all. A vertex map ( VMap) is additional data that a user can add onto each point in an object. Points even have rotational information, although you normally don’t rotate individual points.

As you might expect, every point in an object has independent position information.
