I would like to create an environment map material to give my model mirror-like surface. Is this possible in the node material editor?
I’m not really sure what you want to achieve…
Environment maps are normally either created in external programs and exported as cube or equirectangular textures, or created at runtime by using a reflection probe.
If you want to create a mirror-like material, you should set
roughness=0 - these parameters are not linked to the environment map used.
In my case, I am generating the world in - so your recommendation of the reflectionProbe is what I was looking for.
