Here's mine. it's a pretty cool shader node graph that was generating 50% of static textures in our game. Yes, static textures that could be easily replaced with some texture files, which was my original intent. Instead, we had this pretty graph used every frame for basically a majority of pixels on screen. But it's not like it would do much damage performance-wise, right?

In any case, this is now a thing of the past, as I've replaced all materials using this shader with static texture files, as well as removed some other potential performance issues. They said we need to make a game in three days, but they didn't say it has to run smoothly lol.

Anyway, pretty random post, thought it's worth sharing (no, it's totally not made to encourage y'all to play this very cool escape-room puzzle game we've created called Exit, which you can play on Web, Windows or Linux). Does your project have any cool shader nodes or any other nodes you want to share?!
