I created a room (floor, table, walls and windows). For the windows' faces, I used a material with the following features (I list below only the features I changed, the remaining ones kept standard, ie, as they came):

  • Principled BSDF
  • Base color: white
  • Specular: 0.15
  • Roughness: 0
  • IOR: 1.5
  • Transmission: 1
  • Emission strenght: 0

I checked Screen Space Reflection both in materials and in Eevee render.

Finally, I added a reference image with sky and trees to be the outside environment. However, I cannot see the image through the windows (either in material or render mode, independently of rendering in eevee or cycles).

My question is: How to make the windows material transparent so that I can see an image through it?

  • $\begingroup$ Wooow. That works! Thank you! $\endgroup$

When using transparency in EEVEE, make sure to set the material's Blend Mode to something other than Opaque. Alpha-Blend or Alpha Hashed should work fine. For some objects, you may also find things look better if you also enable Backface Culling:
