3ds Max light brown parameters typically refer to the settings used in the software to create a light brown color. In 3ds Max, you can adjust the color by modifying the hue, saturation, and brightness sliders within the material editor. For a light brown, you might set the hue around 30-40 degrees on the color wheel, the saturation around 40-60%, and the brightness around 80-90%. These values are approximate and can be adjusted to achieve the desired shade of light brown.
