The trans material primitive takes the form: mod trans name 0 0 7 A1 A2 A3 A4 A5 A6 A7 A7 = Ts / (Td+Ts) A6 = (Td+Ts) / (Rd+Td+Ts) A5 = Roughness A4 = Rs A3 = Cb / ( (1-Rs) * (1-A6) ) A2 = Cg / ( (1-Rs) * (1-A6) ) A1 = Cr / ( (1-Rs) * (1-A6) ) Cr, Cg and Cb are the red, green and blue diffuse reflectances. Rd is the photopic average of the colored reflectances.
