Why do I see the light in the reflection (EEVEE) even if the material is not reflective? As the title says...
I have a transparent (glass or full transmission in the principled shader) plane, but I see the reflection of my area-light although the material is not reflective. The only way it disappears is when I set the IOR on the plane to 1, which defeats the purpose of my setup.
Any ideas? Bug?
According to the manual:


  The Glass BSDF node is used to add a Glass-like shader mixing refraction and reflection at grazing angles. Glass BSDF


That's why you see reflections with this kind of shader.

If you don't need reflections on the object - use Refraction BSDF
