Alright I looked at Making a realistic infinite mirror tunnel and am trying to make an infinite mirror room in 2.8 eevee.
The answer says to increase light path bounces, but obviously this doesnt apply in eevee where lighting settings are limited to:
What Ive tried is making a mirror material (100% metallic, 0% rough) and put a reflection plane on every wall. I then upped the distance to like 5m on each -
however I still get maybe one reflection of the center object at best. How can I do this in eevee?
