Euler Rotation in Unity

// Create a Ra matrix Euler(30, 60, 45)
Matrix4x4 ra = Matrix4x4.Rotate(Quaternion.Euler(30, 60, 45));
// Create a Rb matrix rz -> rx -> ry
Matrix4x4 rz = Matrix4x4.Rotate(Quaternion.Euler(0, 0, 45));
Matrix4x4 rx = Matrix4x4.Rotate(Quaternion.Euler(30, 0, 0));
Matrix4x4 ry = Matrix4x4.Rotate(Quaternion.Euler(0, 60, 0));
Matrix4x4 rb = ry * rx * rz; // Z → X → Y

// ra == rb

// Create a Rc matrix ry -> rx -> rz
Matrix4x4 rc = rz * rx * ry; // Y → X → Z

// rb != rc
