Adding reflection to a plane while keeping a perfect white emission I want to have a perfectly white background with a reflection of an object. For the perfect white, I decided to use a emissive color, the result is as I expected.

Now if I mix a Glossy BSDF, I have my reflection, but the white is not as perfect as it was before mixing the shaders. Playing with the Fac-value is not bringing be further, because I need the white to be perfect, not with a tradeoff.

Is there a way to achieve this?

Please don't go too harsh on me, since I'm a beginner :D



Thank you for your help!
Final:



Nodes and overview:


You will need to create "fake PBR" shader by mixing Diffuse with Glossy by Fresnel.
Glossy should have set 0 Roughness and Color to pure white.
Mix them with Emission shader - again by Fresnel.





  Note:
  
  I've used black Environment color to show that Emission and Reflection
  is working, if you set it to white, like in every else node it will
  give you wanted result.
