Issues with Y Normal Channel View in Render

Hello there!

I am having some issues when I try to extract the Normal channels after rendering. I am able to extract the X and Z Normal Channel, but it does not show me the Y channel for some reason. I attached some pictures for reference.

Thank you so much in advance!

Hello - the channels only show if you can see that side of the box from the current view. That is, the side facing +y, + x, +z… @andy, I am not sure what is expected for this - is that the correct result?
