Let me start off by saying SHADER CODE IS SO COOL. I really enjoy learning about shader code, and plan on getting good with it as time goes on. As of right now, however, when I make a shader I start out with my own idea, plan, and math function(s) to make the shader, but then have AI write most of the shader code for me, as I am not able to do it as well as AI can quite yet.

The shader code I'm most proud of is the code that manipulates a small rectangular plane into a stylized blade of grass. The GIF below shows this blade:

I used the following simple graph that I made in Desmos to make the curve of the blade, and then had Gemini apply this function to the plane. I also had Gemini apply a gradient color to the blade so that the lower down on the blade the darker it gets. I also made sure to add parameters, so the width, height, and position of the 'bump' (the part that I cared most about) would be editable so that I could tweak it to look nice on the grass blade.

With this (and another grass clump variation that I made in blender) I was able to make scenes like these in the game:

Something else I did at the end was just have Gemini add wind to the grass by using a noise texture that moved in a specific direction, and deforming the grass in that specific direction according to the noise texture. The results look quite nice in my opinion:
