Change Details

**A first crude version - subject for a future refining. Untested.** Adds Eevee hair shader replicating Cycles' [[ https://doi.org/10.1111/cgf.12830 | CBTB16 ]]. {F9887868}{F9887869}{F9887870} Implementation is similar to Glossy, except that reflection directions are chosen according to inner hair reflections. Current limitations: - Color is off from Cycles - No SSR - No isotropic reflection (TRRT+) - Radial roughness is set equal to roughness.
