Strength
Strength set to a low value (left) and high value (right).
Strength generally denes how bright the SSS effect will look in the material. Adjust this parameter rst when
setting up a new SSS material.
Filter Length
Filter Length set to a low value (left) and high value (right).
The Filter Length parameter denes how deep the gradient travels into the material. The right edge of the
gradient corresponds to the Filter Length value.
Absorption
Absorption Filter set to a low value (left) and high value (right).
Absorption is measured in meters and represents how far the light can pass through the material before it
is fully absorbed. Use very small values for opaque materials. Very large values will hardly stop the light. The
greater the Absorption value, the less inuence the color of the Absorption Filter will have.
