Bounces – The number of indirect bounces used to compute the effect of the multiple scattering. It can significantly affect the hair appearance, especially for light colored hairs. The number of bounces necessary can vary from 5 for dark colored hairs, to 30 and more for light colored ones.
Compensate energy - When enabled, compensates for a lack of light bounces in areas where the hair is denser and light cannot pass sufficiently.
