Here is a mock up scene showing all the props I created from the "Tank Game" game jam I participated in last summer. Working title "Tank Game" is a low-poly twin-stick shooter game where you play as a treasure hunter who is trying to protect your booty from other enemy subs who want to take it for themselves. The game began development in the Unity engine.
I used Unity's post-processing effects systems to create the blueish-green overlays and camera distortions in Unity, and I wrote the sand ground shader inside the Unity graph editor following this tutorial by Ned Makes Games - https://www.youtube.com/watch?v=KqWfo6EPjCw
