As you know, I had some problems with Unity 3D and the game project North. The reason was the non-activation of the Windows OS operating system and some network problems. That's how we continued from the beginning with the Godot game engine that switched to the C# language. At this moment I worked on some shaders. The new version I'm working on is 4.1.2 and it's still not very well documented for the custom implementation of Godot shaders with gdshader type files.
Here are some new examples:
Halo sun shader
Smoke sphere shader
Basic fire shader
