Thanks again Wes,
I did try it and it still gives me no results in Unity on rotation for the sbsar I want it to happen on.
However, when I created a brand new file with a simple shape, rotation & scale did work inside of Unity, did the same thing with Matrix multiply.
Hence, I removed all the game related images from the multi-switch node and added shape nodes, so I can share it safetly. And I have attached it here - on this sbs file the rotation isn't working even though I did what you asked me to and followed all the necessary tips.
I am really not able to pin point where I might be going wrong.
Thanks a lot.
