For the artist or engineer who demands that a glass of whiskey renders with correct dispersion, a leather chair shows true anisotropic grain, or a stainless steel surface reflects with precise chromaticity, the .mxm remains an indispensable tool. However, in an industry moving toward open, real-time interoperability, the future of .mxm lies in specialized, high-end niches where accuracy trumps workflow convenience.
