Open 3d 4x4 Transformation to Unity

[jacopomstrada]

Hi, I'm trying to use a transformation obtained with a point cloud registration and apply it to an object in Unity. I know that Unity uses different coordinate conventions (right-hand vs. left-hand), but I'm having difficulty transforming the matrix so that I can use it.
I have found several conversion methods, but I have not been able to obtain consistent results.
Any help would be highly appreciated, thanks!
