This is mine ideas or suggestions.
There are several ideas to make a Sci-Fi Futuristic game look good
Such as:
- You could include Doors that open when the player is within a radius of meters indicated.
- The use of the material “Neon” It will be quite important for your game to look good.
- Consider placing a “SkyBox” Dark, In this way, the scarcity or abundance of light will remain with a more refined touch.
- Be careful when adding metals with a color tone too light, because with light, a dark skybox, and also the light metal, this will look too bright (it’s just a suggestion)
That’s all I can contribute with.
