"Portal Remastered" is a recreation of Valve's game from 2007, made with Unreal Engine 4. The main goal of the game is to recreate the first Portal game, without all graphical inconsistencies created by all differences between the first game and its sequel (like elevators between levels, GLaDOS appearance...).
There is a screenshot from the observation room near the spawn area in Portal Remastered, on the 22nd of July 2017.
I think alot more could be done with this, so much potential and both in props decals and lighting still far to go.
I don't want to have an overlighted level by the way, I still need to find a compromise, but I'm still working on that, don't worry. I'm testing different lightning ;)
