Wow thank you so much I just dove in to the source code, while also reading the entirety of the book of shaders. Look like you're right! I remember reading somewhere, WebGL1.0 can't do dynamic loops, they have to be fixed, and I found this myself :) Pretty proud of myself! haha.
I'm going through one line at a time learning how your genius came up with this.
Thank you so much for looking in to this for me!
