What is subsurface scattering in Maya?
Sub-Surface Scattering (SSS) simulates the effect of light entering an object and scattering beneath its surface. Not all light reflects from a surface. Some of it will penetrate below the surface of an illuminated object. There it will be absorbed by the material and scattered internally.
Why is subsurface scattering red?
The darker the color the more light is scattered. A value of 1 will produce no scattering effect. So if you set it to green, the lit areas of the object will appear as green, and green is scattered only a little. Therefore the darker areas will appear in red and blue.
What is subsurface radius?
The Subsurface Radius attribute sets the light penetration distance inside the material.
What is subsurface scattering blender?
Simulates semi-translucent objects in which light rays enter, bounce around, then exit in a different place. Many organic and inorganic materials are not totally opaque right at the surface, so light does not just bounce off the top surface.
What is subsurface blender?
Simulates semi-translucent objects in which light rays enter, bounce around, then exit in a different place. Instead, some light also penetrates the skin surface deeply, and scatters around inside, taking on the color of the insides and emerging back out at a different location. …
What is subsurface scattering map?
The Subsurface scattering (SSS) channel simulates the effect of light scattering inside an object. It is useful for translucent materials like skin, wax, and ice. The Subsurface scattering texture is a grayscale image. It works as a mask to indicate where the effect is visible and how strong it is.
What are the effects of sub-surface scattering?
Subsurface scattering is responsible for effects like color bleeding inside materials, or the diffusion of light across shadow boundaries. The photograph below shows an example of translucent objects.
What is the importance of surface scattering in art?
Subsurface scattering is an important effect for realistic rendering of translucent materials such as skin, flesh, fat, fruits, milk, marble, and many others. Subsurface scattering is responsible for effects like color bleeding inside materials, or the diffusion of light across shadow boundaries.
What is the difference between Lambert BRDF and subsurface scattering?
As we can easily see from the comparison, subsurface scattering shows a more waxy feeling, it feels more transparent than the Lambert BRDF. In a nutshell, subsurface scattering means the incoming light penetrates through the surface of an object and leaves from another position that may not be the same as the position where it enters the surface.
How do you simulate multiple scattering?
Multiple scattering is approximated as a diffusion process. This is done in four steps: 1) baking the diffuse surface transmission of direct illumination into a point cloud file; 2) diffusion simulation using the ptfilter program; 3) creating a brick map file; 4) rendering the final image with subsurface scattering.
