Heloo! My theory is that opaque emissive materials make a scene look modern - by that I mean the portal. Opaque - we can't see through it / Emissive - it emits light. The portal is neither reflective nor translucent, either of which, in addition to some non-solid effects like some sort of fog, particles, plumes, lightning, rays, smoke, light bending, glares, blooms, explosions or something could greatly expand the scene. It's not necessary to draw the whole viewport behind the portal or a mirror-like reflection of the city if its covered up by the effects, but a part of the viewport or the reflection could go a long way here. The lighting is very lovely. Cheers | Artwod Feedback
