The Instance Duplicate Maps utility searches
an entire scene for materials that have duplicate
Bitmap maps and give you the option to instance
them. If your scene has different materials that
use the same texture maps, creating instances will
reduce the load on your video card, which can
improve viewport performance.
For example, if you’re rendering a scene that has
three materials that reference the texture map,
MyMap.bmp , the software will search for t hat
texture map three times, once for each material it
is used in. If you use the Instance Duplicate Maps
utility, you can create instances of the duplicate
maps so the renderer will find the first reference
to
MyMap.bmp and use it for any subsequent
material that uses the same maps.
This utility searches an entire scene. You do not
need to select objects or materials.
Note: Inordertobeeligibleforinstancing,the
Bitmap maps must be identical in a ll aspects w ith
regard to their initial settings. For example, if
two materials use the same bitmap ima ge applied
as Diffuse maps, but have different initial Tiling
settings, their m aps aren’t eligible for instancing.

determining duplication, so any differences in
the animation of Bitmap map parameters will be
lost from the use of this utility. For example, if

different subsequent va lues, after using the utility
both maps wil l have the same a nimation as the
first map.
