We emphasize the importance of methods explicitly considering microgeometry, particularly when combined with efficient volumetric representations. Decoupling of small-scale geometric structure and optical properties allows for the most comprehensive edits while still achieving physically plausible results, even for optically complex materials such as cloth.
