Glass pane not acting the way it should Hello guys,

thanks for clicking this post,

I am trying to make a basic cableway but unfortunately I got stuck at one point. I was trying to put there windows but the glass panes don´t seem to work properly. They are not solid, just regular planes with a material which I´ll put a screenshot of. It looks as if they had different behavior on each side but I don´t understand why. Can you help me find the solution?


One side of the cableway (this one looks good)


and the other side... (Same lighting and everything, just different camera position)


... And this is the material I use for the glass panes.

Thanks for your time, Daniel!
Your 'Fake Glass' using a single plane instead of a solid works as expected when the plane is viewed from the 'front' side (the side that the normal is facing) but the Fresnel node produces different results when viewed from the 'back'. In order to correct for this you need to adjust the IOR to 1/IOR when viewing the surface from the 'back' and this can be achieved as follows :



Here the Backfacing geometry node controls the Mix between IOR and 1/IOR so that when viewed from the 'back' of the surface it still behaves the same as from the 'front'.

Replace the Fresnel node in your example with the above nodes and this should resolve your problem.
