PhysicMaterial.bounceCombine
var bounceCombine: PhysicMaterialCombine;
Description

Determines how the bounciness is combined.

Traditionally bounciness properties are dependent on the combination of the two materials in contact. This is however impractical in a game. Instead you can use the combine mode to tune how the bounciness values of two materials are combined.
