Custom attributes set by the Set Data from Chunk to help identify and visualize the chunks after a simple shatter.
ChunkID is an integer per vertex. All vertices in the same chunk have the same ChunkID. You can use this attribute to process
the chunks later in the same tree or another tree.
ChunkColor is a color per polygon. All polygons in the same chunk have the same ChunkID. You can use it to distinguish the
chunks in the viewports by using the color in the render tree.
For these attributes to be set properly, the value of must be greater than 0 in Build Slice Planes
