BABYLON.Matrix.RotationXToRef(Math.PI, reflectionMatrix) (or Y or Z).
Although, when running my code, the reflection is not affected at all.
I set up a playground with a change of the X, Y and Z to the reflection-matrix of one sphere. Although, there is no change of the reflection compared to the second sphere which has an unaltered version of the reflection-matrix:
