Great job and very inspiring! Thanks for sharing.
Frankly I do not understand why we talk about the past of this CEO. As a player I do not care about what he did or not until his games are good. As an Environmental Artist instead I see a game with a shaky graphics. It is completely without personality, emotion and involvement. It can hardly be considered acceptable especially for the 2019 platforms (which I understand will be the target of this game). Well, this is probably an indie group, with no experience facing a first game in the real market. And that's fine. Do the best you can that even if you fail, you will learn and do better. From a technical point of view the method you are using is very old. It can work but not as you are doing it. I bet you're using Unity, it's easy to see that since I see assets from their asset store. Break your landscapes more, they are too monotonous and contact real 3D artists and level designers. One last thing, the last screenshot is worse than all the previous ones. The lights are wrong and everything screams disaster. Avoid similar disasters in the future.
But are they real or is it a mockery? or a scam? Truly horrible flat graphics and lacking a real sense of aesthetics. Ui devoid of consistency and usability. Do they really have a graphic art department? Imho in 2018 using such tricks so massively denotes profound technical incompetence.
This material creation tutorial by Emre Karabacak has shared a material creation tutorial that will guide through all the essential steps of building a concrete tile material in Substance Designer. The thing here is that once you understand the principle, you can create all kinds of tile materials. The sky’s the limit.
In the end you’ll be importing the resulting texture maps into Marmoset Toolbag and using the result as an Unreal Engine 4 PBR shader.
The first part of the tutorial is about setting up the material in Substance Designer:
The second one will tell you how to create a new shader in Marmoset Toolbag:
