In this paper we explore the intricate relationship between volumetric albedo and attenuation. When rendering realistic skin and complex FX elements, the traditional approach of authoring absorption and scattering can pose a challenge when trying to achieve a desired opacity, brightness and saturation. The alternate parameterisation of albedo and attenuation can also produce unpredictable results. Focusing on Mie and Rayleigh scattering, we develop three novel techniques that derive physically plausible attenuation values from albedo. By understanding the implications of Rayleigh scattering, and adjusting albedo in an intuitive manner, artists can achieve predictable and consistent results with volumetric rendering workflows.
