If you liked this, I suggest you look at Fortnite: https://www.shaderbits.com/blog/octahedral-impostors However, let me point out a very big gotcha with this technology: Usually, outputting a custom z-depth will disable any sort of early z-culling in the GPU. That means the performance hit of drawing this might be huge, and even more costly than draw…
