CINEMA 4D R11 Quickstart – Materials
Here are some more tips about channels for you to try:
Got dirt? CINEMA 4D does! Most objects in the real world are not as clean and immaculate as they might appear
in CINEMA 4D. Real stone figures show signs of weathering over the years and dirt has settled in the wrinkles
and cracks. You can simulate such “dirt“ very easily with CINEMA 4D (if you own the Advanced Render module)
by selecting the “Ambient Occlusion” in the main page’s “Effects” menu..
If you own the “Advanced Render“ module (or are testing the CINEMA 4D demo version) you can render human
skin, for example, very realistically. The Sub Surface Scattering makes it possible. By placing this shader in the
luminance channel (effects / sub-surface scattering) the effect is created when rays of light meet a slightly
transparent object. Some rays infiltrate the object further and are dispersed, others are directly absorbed or
bounce off. Further possible uses for this effect would be for materials such as plastic, milk, candle wax or
figurines made of jade.
You can load black & white textures into the alpha channel to influence the material based on the texture’s
brightness, similar to the way you would use them for the bump or displacement channels. The texture’s black
areas would be rendered with a transparency of 100%. As the texture becomes brighter the transparency is
reduced accordingly. White would have a transparency of 0%
If you choose “Shader“ instead of “New Material“ under “File“ in the Material Manager you will see a list of 3D
shader presets. The advantage of these shaders is that you don’t have to worry about mapping your texture
or seams in your texture because a 3D shader will be calculated for the 3D space. Here are a couple described
in detail:
Cheen: Generates an electron microscope effect good for the depiction of bacteria or mites.
Danel: Very good for simulating high-gloss finish Banzi: Lets you depict various types of wood.
