■ 1:map The default mapping channel. You can transfer all UVW mapping information between objects with the same topology by copying and pasting this channel. You can create additional mapping channels by various means, including with the Channel Info utility. Channel Name The name of the channel. By default, a channel has no name, as indicated by the entry "-none-". To name or rename the channel, click the channel to highlight it and then click the Name button at the top of the dialog, or right-click the channel and choose Name from the right-click menu. NOTE Most channels can be split into subcomponents on page 6050. You can name the subcomponents separately from the channel itself. Num Verts The number of vertices in the channel. To paste one channel to another, they must have the same number of vertices. Some channels have faces but no vertices. This is typically the case with Alpha, Illumination, and vertex color channels in newly created non-poly objects. In such cases, these channels function as placeholders for the corresponding data should you add it later. They do consume a small amount of memory, so if you have no intention of using a channel, you can save some memory by converting the object to Editable Poly. Num Faces The number of faces in the channel. If a channel has faces but not vertices, that means it's a placeholder. See Num Verts, above, for more information. Dead Verts The number of unused map vertices in the channel. Such vertices can be left over from sub-object editing. Size(KB) The approximate amount of memory consumed by the channel. Use this figure to check for unused channels that are using up memory.
