Great Tools For Creating Complex 3D Materials
At the material level, your 3D application offers several material types that are great tools for creating complex materials. They include:
Blend Enables unlimited levels of blended and masked materials to be on top of materials on top of materials.
Top/Bottom Materials that are different at the top of an object than at the bottom, such as a boat that has sat in the water for a while, or an object that has sat in strong sunlight and faded on the top but not on the bottom.
In your 3D application, top can be defined in terms of World or Local axis.
Double Sided Reduce complexity of mesh objects by applying two materials, one on the side with face normals, the other on the back side. This is good for creating pages of a book from a Quad Patch or a floor/ceiling for an architectural project.
You can set the back material to “bleed” through to the front, simulating translucency.
Multi/Sub-Object A combination of materials each assigned to faces with a corresponding Material ID number. Each Sub-Object material can be as simple or as complex as you need.
You might, for example, create a ballpoint pen as one mesh object and then assign Material ID numbers to the cap, the body, and the bezel. You then create a Multi/Sub-Object material with three colors and textures to correspond to the IDs. When you have the material defined, you can add the grunge details by using the various mapping types.
Do not be afraid to experiment, and Do not become blinded by the map name. Noise can easily be defined as smudge or blotch. Some of the your 3D application map type possibilities are:
Cellular Use this map type to simulate a growing cell pattern in a stone dish or a “cracked earth” type pattern. It is useful for bump and diffuse color textures.
Falloff This new map type causes a falloff effect based on distance. The direction of falloff can be according to World or Local axis, viewing direction, or a particular object. You can use it to enhance depth in a scene; it performs best as a mask or modifier to diffuse, bump, or opacity maps.
Output, RGB Multiply, RGB Tint Mimic the controls of the same names found in the roll outs of bitmaps and are useful to add their namesake effects to map types that Do not have them built in. For instance, you can use an Output map in the Diffuse slot and then add a Dent map as an Output sub-map to add the Output controls to a Dent map type.
Smoke, Speckle, Splat Procedural maps such as Noise, but with different patterns. They are excellent for random bump or opacity effects and can be powerful grunge tools when used as masks and Mix or Composite maps.
Smoke can be effective as a Shininess or Shin.Strength map to break or boost the surface shininess subtly.
Thin Wall Refraction Gives the illusion of the jog visible when you put a pencil in a glass of water. Your 3D application refraction, however, made only bitmaps appear refracted, not objects.
