I don't know how it happened, but somehow I've finally clicked with shaders.
The project I'm working on at the moment has been quite challenging and more often that not these days, I get the inspiration to solve the issue with a shader.
My current project is already using several shaders, which are either for procedural generation or real-time.
I've just made my first practical vertex oriented shader where I can basically crop an object rendering on a world axis (e.g. clip it on the horizon). While I was all giddy about it, I even put an alpha fade on the crop with no drama.
So my question is, I find myself with at least 4 copies of notepad open editing shaders / looking at other shaders.
Is there a decent editor / workflow / debugger for shader writing? I have used shadertoy before, but if you want to use AppGameKit variables, it's not much use.
