Which factors should I look at to make the reflection as neat as that of the reference image?
Some of the thigs I've tried:
Increasing roughness, but still have too many distorted reflections and also I can't see the yellow sphere in the cube clearly like the reference image.
Changing variables on Ray visibility, but nothing seemed to work. Material of the cube is set to default material with : Specular 0.5 / Roughness 0 / Transmission 1 level
My Cube – Bottom and left sides has way too many distortions.
