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 with 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. Clean Deletes unused sub-materials from Multi/Sub-Object materials that are turned on. Cancel Cancels the operation. Instance Duplicate Maps 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 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 render a scene containing three materials that reference the texture map MyMap.bmp, the software searches for that texture map three times: once for each material it is used in. However, 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 In order to be eligible for instancing, the Bitmap maps must be identical in all aspects with regard to their initial settings. For example, if two materials use the same bitmap image applied as Diffuse maps, but have different initial Tiling settings, their maps aren't eligible for instancing. Animation is not supported as a criterion for determining duplication, so any differences in the animation of Bitmap map parameters will be lost from the use of this utility. For example, if two materials use the same bitmap image applied as Diffuse maps, and have the same initial Tiling settings, but their 6058 | Chapter 19 Material Editor, Materials, and Maps
