Mode for combining material properties (friction, restitution) when two bodies collide. Determines how to calculate the effective value from both bodies' properties.
average: (a + b) / 2
geometric mean: sqrt(a * b)
maximum: max(a, b) - Use the larger value
minimum: min(a, b) - Use the smaller value
multiply: a * b
