The purpose of this shader project is to allow students to creatively apply any shader effect of their choice to a snake model. I chose to implement a fire effect and I modified the snake model to my liking in blender.
First, I had to figure out how to make a fire shader work. I had something working, but I was using the default generated Glman noise, which I did not like the look of. I found a nice noise texture online that made the fire look closer to what I imagined. I then used octaves to make the fire look a little more natural. At this point, the fire was more of a “realistic” fire where the edges faded. I wanted to make it look more cartoonish, so I cut it more abruptly. Unfortunately, I had an issue where it would make half of the vertices the color of the background and half of them invisible. I fixed this by just discarding it instead of changing the alpha.
I tried the fire shader on just the snake, which looked boring. So, I used a blender to create a crest for the fish. This is where all the problems began. I have not really used a Blender before, but I eventually figured out how to make a plane and bevel the edges. It looked good in a blender, but for some reason, the sides of the crest would never show up in my shader. I tried a few different things, and after remeshing the object, I finally got it to appear in my shader. But then I had a new problem: my shader worked on the snake, but when it got to the crest, the whole crest acted as if it was one pixel (it was one color and would not fade). I could not figure this out, but then I had the idea to use the blade of a sword instead of a crest that I made, which worked out fine.
