THIS GUY BUILT A FULL TOWER DEFENSE GAME USING CODEX + GPT-5.5 AND THEN ADDED A CUSTOM SOUL EATER MOON 3D ASSET IN A SINGLE SESSION While most people still use AI just for research or generating random images, others are building things like this A fully working map...

vibe coding metahuman with threejs and codex: spitting FACS ok, i'll admit 3D modeling has a lot of depth, going from a cube to a full facial action coding system is.. a lot of work, but really it isn't all that hard to learn like some people want you to believe it took me about 10 evenings to go from scratch (no idea how to even model in blender beyond the famous donut) to a working rigged and shape keyed expression system the actual vibe coding parts are very manageable, i'm not even hitting any session limits the past week since codex is basically just reading the glb file and it writes the drivers to have a full animation system in a single turn after that i usually notice that some things don't look as professional as i like it to be, followed by codex sending my ass back to blender and telling me what i need to do to make it better so here we are, the expression system is still very very simplified, no micro expressions yet and i believe i will need probably 500+ shape keys to actual achieve realism, but why not? Doing the 52 ARKit expressions for this demo wasn't too hard either, just tedious and boring The final driver in the demo uses a mix of bone movements and blendshapes to smoothly animate the face I might mix up some terminology here but i usually do cause it's been like what, 10 days since i started? Guess next up i'll look into face deformation parameters and then we'll move to the fun part of skinning. Once the head/neck area works (hairs are also still missing), full body next and finally LOD systems and we can call it a day Demo (pls use a desktop i'm not optimizing the ui for mobile):

Here is the Geometry Nodes Weighted Normals with Laplacian Blur on a full character (a vroid). It easily improves the shading even on game topology with almost no setup. I built this as part of my quest to improve real time toon shading. 3D anime models are popular, but use of dynamic light is rare even among high quality vtuber models. This is for several reasons, but a big one is simply that it takes a lot of Custom Normals work to make 3D cel shading not look like a jagged mess (other pieces of the puzzle are issues like deformations, multiple lights, etc). And fixing Normals is tedious, especially on existing game topology. I have focused on proxy meshes for priority areas like character faces, but they aren't an efficient solution for the whole body + outfit. I wanted something I could just throw on any model and make it at least not a jagged mess anymore even if it wasn't perfect. As you can see from this clip, this does that very well! And vertex groups can be used to control the style of the effect and power. It still can't smooth beyond what the topology density can support, but the topo itself is no longer a problem (for higher res, could be run on a subdivided version of the model and then baked to a Normal Map.) The only changes I made to this model were adding a weld modifier to merge split edges during interpolation, and a vertex group to select the skirt. I have not yet added full handling and logic for detecting edges with big angles like the skirt, or for handling boundaries like on the hair, so both those areas can get better too. You can also see that while it successfully smooths out the Face, it isn't really stylistically correct there. That is still best done with a proxy mesh to define a new shape. This is part of the tools I am working on for Fondant. We are putting together a Blender Addon to release this + a proxy mesh tool for the face, and are working on resolving other problems in-engine to fully bring dynamic light to real time 3D toon shading. Give us a follow, and send them a DM if you are interested in testing these tools as they develop!
