To mix metallic 3D models effectively, prioritize matching finishes, testing light, and starting simple—these tips create balanced, realistic results.
Match material finishes (e.g., brushed vs. polished) to keep metals cohesive; clashing textures make designs look disjointed, whether for prototypes (aluminum + steel) or game assets (gold + chrome).
Test light interactions early: Metals reflect differently, so checking how they react to scene lighting prevents harsh or muddy reflections.
Start with two similar metals (stainless steel + titanium) before adding high-contrast options like copper—this simplifies the process and avoids overwhelming the design.
