Kimi K3.1 Pro: How to Build 3D Worlds!

Julian Goldie (0:00)

K31 Pro is the newest AI model from Moonshot, and I just used it to build six full 3D worlds in Blender. A rainy neon valley, a zen garden, a space station over a planet, floating islands, a crystal cave in a desert with two moons. No 3D artists, no downloaded models, no textures, just one paragraph of text for each world. And all six cost me $8.80.

So in this video, I'll show you every world and exactly how I made them, how you can use them too.

Now, the old way versus the new way. Here's the old way. You learn Blender, that takes months. Then you model every object by hand, every wall, every tree, every light, and you set up the materials, you set up the camera. One scene like this can take days. The new way is you write one paragraph, Kimi K31 Pro writes a code, and Blender builds a world. You don't touch or model anything. You don't touch a code. You just look at the picture and tell it what to change. And let me show you what came out here. So the six worlds. So this is Neon Alley, rain falling, neon signs stacked up to the walls, puddles reflecting every color, and a lone figure standing at the end of the alley, right? Kimi wrote 1,633 lines of code to build this one world. Every object in it is made from code. Now, this is the Zen Garden, red maple trees, a wooden pavilion sitting on a koi pond, glowing stone lanterns, and gravel circles. None of it was modelled by Hand Ivo. Also got the orbital station, the floating isles, which are islands in the sky, a little shrine with a lantern, and a waterfall pouring off the edge into the clouds. We have crystal cavern, giant glowing crystals, a still lake reflecting them like a mirror, and a beam of daylight falling through the roof. And we've also got the desert monolith, so two moons, a huge glowing monolith, and a tiny traveler walking towards it. So you can even see the footprints in the sand. Now, how does this actually work? There's four simple steps to generate 3D worlds like this. Step number one, I write one paragraph describing the world. Something like a rain-soaked cyberpunk alley at night, neon signs, puddles, one figure at the end. Step number two, I send that paragraph to Kimi K31 Pro, and it writes a complete Blender script, over a thousand lines of code. Every shape, every material, every light in the camera. Step three, Blender runs that script on my Mac, and actually renders the picture.

Most worlds will actually render in under a minute. And step four is you can look at the picture and send Kimi notes. For example, the fog is too thick, or I want a real beam of light, and the planet looks like marble. Kimi, then, will fix its own code. I don't need to edit a single line myself. Now, the other cool thing about this is you could use it for product promos, you could use it for, for example, creating 3D structures or 3D previews, things that you want to check out. Another cool thing as well, you can get Claude or any other model to actually operate it for you autonomously. It doesn't need to be you giving the feedback directly until the final check. Now, quick one, if you want to build things like this yourself with Kimi, with Blender, and your own AI agents doing the heavy lifting, it's all inside the AI Profile Boardroom. Here's where you get the exact Kimi and Blender setup step by step, how to connect Kimi, what to write in the brief, and the notes to actually fix and render. All my best AI building tutorials and training in one place from your very first prompt to running a whole team of agents, the agent operating system I built, all your agents in one dashboard, sharing one memory so they know your business, your office, and your goals, a 30-day road map, and live coaching course plus daily tutorials. Every time a new model like Kimi K31 Pro comes out, you're never behind and you can DM me directly. If you're stuck on something, link in the comments description or go to the aiprofitbomb.com to get access. Now, let's look at why she makes the world look good. So there's a fix loop, and this is the first render of the Zen Garden, Gray Fog everywhere, and you can barely see anything. And this is the final one after a few rounds of notes. Huge difference, right? That's a loop. So you describe it, you let Kimi build it, you look at it, you send notes, and then you repeat. Now, it wasn't perfect, so two rounds of fixes actually made things worse, right? The cave got washed out with fog, and the desert dunes came out jagged. So you can roll back the better versions and give Kimi just much tighter notes, like for example, change these things only, right? And that actually works. So here's a lesson, like small clear notes beat like big, vague ones every single time when you're going back and forth and iterating on the worlds that you build. Now, let's talk about the numbers here as well. So here's what the whole thing took. Six worlds, over 8,700 lines of code, 21 replies from Kimi and $8.80 in total. Each reply took Kimi about 10 to 25 minutes to think and write, and each render took under a minute on my Mac. Now, a 3D artist could spend days on just one of these scenes, but this was just a paragraph and a few real notes. Also, these aren't flat pictures, right? They're 3D real worlds. You can preview, you can zoom in, you can zoom out. We can add a camera move to each one. You can fly in, pull out, orbit right around, because every object is there in real detail. So quick recap, how do you do this? Well, you write one paragraph, Kimi K31 Pro turns it into Blender code. Blender renders the world. You look at it and you send small, clear notes, then Kimi fixes it. Six worlds for under $9.
