Our project, Aftermath, uses a lot of different tools but for the very last sequence I used Unity and VFX Graph to generate a movie. It was a lot of fun! #madewithunity #projectionmapping #procedural

You can easily build a virtual pottery demo in @splinetool v2. I was blown away by how fast the built-in AI agent is, and by how well it understands physics. You can even shape it from the inside, pushing the clay out to hollow the vase. That vessel section in the top right? The agent suggested it!! So handy. You can use your mouse, or your hands with webcam tracking. I built a tool that follows the shape of the vase, you can also trim off the extra clay. Every element in the scene was created by the agent. I started this demo this morning!! Working with Spline is so fast. Dropping some prompts below to help you build your own.

When I was little, my dream was to build a domino run throughout the whole house. Today, I've created one in a stylized kitchen environment, playable on the web. The advantage of this editor is that there's no limit to your imagination. Every element of the set, along with the code itself, was created in @omma_ai Studio: you can send it any image of an object and it creates the element in 3D for you. Then all you have to do is place it in your scene. Engine: the rendering is Three.js + webGPU and the physics is Box3D

since you guys have been asking, I've made my prototype less one-sided for the UFO 👽 ✨ 🔫 I generated and rigged the lowpoly cops and vehicles in @omma_ai, and also improved the three.js rendering a little bit with dof and ao. Close to releasing it, what's still missing?

ok this time I asked Fable to generate me a particle + trails system based on the skinning velocity, after a few iterations in @omma_ai it came out with these 4 presets! I like the steel wool most, I think it can be used to recreate dr. Strange's portal

I built a Domino editor, a full playground where you can draw your own course, edit curves, and add structures to knock down, bridges, and staircases. Thousands of dominoes can topple in a single chain reaction 🤯 The whole thing was created in @omma_ai Studio. For the physics, I used the Box3D library with Three.js. Works incredibly well!!

Final day of replicating those shitty mobile ads using Box3D in @omma_ai: it's complete! Link below. With people and cars it is way more fun 😈 generated and rigged the models in Omma Studio and then used navcat to transform them into agents. Also added a custom LOD and culling system in #threejs for performance. Here is the playable demo 👇

Day 2 of replicating those shitty mobile ads using Box3D: added a fitting city setting and some manhole lore. Feels fun to play, but the city it needs some life next! The models are all prompted in @omma_ai Studio

Day 1 of replicating those shitty mobile ads using Box3D: added the basic gameplay loop and scoring system, it's working fine! I am using the Box3D WASM port from @isaac_mason_ inside @omma_ai

I transformed the game into a downhill snow run with jumps and added a lowrider-style hydraulic dance mode. I also added a speed FX and a huge downhill track, like a snowboarding game. I still love the snow displacement effect. All of this made with @omma_ai + ThreeJS of course. What should I name this game? Btw, who wants to play it?

asked Fable to improve my rendering of the hairy guy, this looks good enough! took just a few prompts in @omma_ai to get it right, the hair material is just a cheap #tsl LambertNodeMaterial with some custom specular lighting model based on the Kajiya-Kay lobes

cozyness achieved ✅ perfect showcase for the godrays effect 🌞 vibecoded this room, the effects, and also the models in @omma_ai. The cloth and plants sim are from my other demos instead #webgpu #threejs #shaders #gamedev

Day 2! 🖐️ The hand tracking experiment in your browser keeps growing. Added a character gallery, Patrick and SpongeBob now stand alongside Squidward, along with their houses, a bubble particle system, and extra assets. Honestly, building with @omma_ai right now is just too much fun. #threeJs
