1744 Chapter 16: Material Editor, Materials, and Maps
Inter face
The Clean dialog presents you with a list of all
Multi/Sub-Object materials in the scene that
contain unassigned sub-materials. You can then
select materials from w hich to remove unassigned
sub-materials.
The dialog consists of two parts: a status field at
the top and a list of Multi/Sub-Object materials.
Status Field
The Status Field is not interactive. It displays
prompts about the unused materials.
Materials list
This list displays Multi/Sub-Object materials that
have sub-materials that are not currently being
used in the scene. When the Clean MultiMaterial
utility opens, it lists all Multi/Sub-Object materials
w ith unused sub-materials and turns them on to
be cleaned. Click the check box next to a material
name to turn it off and prevent the utility from
cleaning it.
Cle an—Deletes unused sub-materials from
Multi/Sub-Object materials that are turned on.
Cance l—Cancels the operation.
Instance Duplicate M aps Utility
Material Editor > Utilities menu > Instance Duplicate Map
Utilities panel > More button > Instance Duplicate Maps
> Click Find All button.
The Instance Duplicate Maps utility searches
an entire scene for materials that have duplicate
Bitmap maps and give you the opt ion to instance
them. If your scene has differe nt 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 render a scene containing
three materials that reference the texture map
MyMap.bmp, the software searches for that
texturemapthreetimes:onceforeachmaterial
it is used in. However, if you use the Instance
Duplicate Maps utility, you can create instances of
theduplicatemapssotherendererwillfindthe
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 all aspects w ith
regard to their initia l settings. For example, if
twomaterialsusethesamebitmapimageapplied
as Diffuse maps, but have different initial Tiling
settings, their m aps aren’t eligible for instancing.
