I seem to be having a problem with refraction through a window. As you see in the second picture, without the window, the table is positioned normally against the wall. However, with the window in place, once rendered, the table appears to be at an exaggerated refracted angle.
We need more information…
What is the node setup of your glass material? Does it have refractive properties (refraction or glass shaders)?
Does that glass pane have thickness? Or is it just a flat plane?
Never use refractive materials in Cycles on geometry that is physically implausible/impossible.
