GPT-6 Astra Built a 3D Game in 7 Minutes

So Astra is really powerful with Blender MCP, so you can combine Astra and GPT-6 with Blender, as you can see right here, we actually built this game, and it's pretty fun and easy to build, right? So to do this, all we need to do is first of all, come up with the ideas of what we're going to build. Now you might say, why would you use Blender? Blender is like a 3D modeling software, but it's incredibly complex to learn and to build with, right? So if you're not sure, okay, how to use Blender, if you've never used it before, like it could take you like a year to even get anywhere near or anywhere close to being good with using Blender. And so how can you get around that? Well, what you can do is you can connect Astra and GPT-6 directly to Blender. So Blender is a free software. You can see an example right here. This was the 3D model that Astra created for the car game that I just showed you a second ago. And then if we go back to ChatGPT, as you can see right here, well, it's actually Codex that we're using, but ChatGPT app. The first thing that I'd recommend is that you come up with like ideas for what you could build. If you don't have any ideas off the top of your head, you can always say to ChatGPT, okay, create five to 10 ideas for what we could use Blender 4 or Astra 6, including 3D modeling games and some cool stuff like that, or maybe even the 3D world as well. Include ideas for what we could build with, along with why it's impressive, why we should build it, a rating for which ones will be the most visually impressive and the most impressive overall. Then give me the ideas first, and we can start building them later. You'll get 10 ideas. About 50 to 60% of them are gonna be pretty bad, to be honest with you.

That's okay, because what we're gonna do from here is we're just gonna cherry pick the ones we like the most to out frame. So if I look through this table of ideas, which you can see, and we're gonna open up this full screen. So when I look through this list, honestly, stuff like an interactive AR profit boardroom, I don't think it's gonna be that interesting or look that nice when it's actually implemented.

The same for example, if I look at this option here, I don't think that's gonna be particularly interesting either. Although we can, do you know what, we can test it, but we'll come back to that later, and you can see the visual impacts and overall impact ratings on the right hand side as well. So it gives you lots of ideas, you have to have a lot of bad ideas to have a good one. And then once you're happy with one of these ideas, then you can actually fork the conversation. All right, so we've got this folder, and it's called Blender. Now, what I wanna do is put and keep all of my projects for Blender inside one place. You might say why, I just tend to find like it gets a little bit overwhelming, a little bit hard to navigate everything inside ChatGPT. So if I look through all the stuff that I built, like we built some amazing stuff, like really, really cool. But the problem is like sometimes it disappears, sometimes, for example, it's pretty hard to find what we've done. Sometimes it just kind of like drops down to the end of the Chat and I can't find it anymore.

And so what I prefer to do instead is create one folder, where I've got everything in one place, right? And I would recommend the same to you. And then also the cool thing about this is, like let's say you want to build multiple projects. So if we look at this, for example, we have the 10 ideas, and ideally you want to generate them in parallel, not in multiple, not like in, you know, one by one. One by one could be quite slow. Whereas for example, you can create like different instances of Blender, different windows. You know, you can open up a different window, a different project, and then you can have Astra just orchestrating Blender for you. Now you might also say at this point, okay, how do you connect Blender MCP to Chat GBT? So it's pretty simple and easy. What you're going to do is you're going to just ask Chat GBT to use Blender MCP. Like we're at the point now where you don't need to be technical to set anything up. You don't need to be technical to come up with ideas. You don't need to be technical to set up an MCP even. You just ask Astra to do it, and it does it for you. And you know, people are like, well, how do I do this? How do I do that? You just ask Chat GBT to do it. That's it. But lastly, there's no secret here. I'm not a technical person, but I can just ask Chat GBT to start building stuff with this. So if we have a look at this, and we have a look at this situation, Brian, we said, can you create a 3D racing game using Blender MCP? Use Blender to model a 3D racing game. Use your image generation skill. This is quite key as well. You want to make sure it uses this image generation skill to generate a setup itself. You might say, well, why would you use the image generation skill if you've got Blender? Because Blender is 3D modeling, so you need an image to start with, and that's why you get the image from ChatGPT. ChatGPT can then create it and plug it into Blender directly. You can also use something called 3DS game director skill, which is a free skill you can get on GitHub, and that can create 3D games. So you can combine a free skill from GitHub for game design. Then you can use the free Blender MCP. You can use Blender, which is free itself, and then the only thing you're paying for is your ChatGPT subscription, which is pretty nice. And so if we scroll down here, you can see the ChatGPT is now asking to access Blender, right? And so you just have to allow the permissions as well, because it's basically using computer use when it connects to Blender as well, because, you know, Blender is working locally on your setup. You see we have two windows open for Blender, so this one and this one, right? So it's been set up, and you can see the 3D world over here as well. It's being built in the background whilst I'm talking to you. So when we were looking at that living city idea, you can see the ChatGPT has generated the image for it, and then it's going to turn that into a 3D model, which we'll come on to later, which is pretty nice. Now, another question that we had here, and if you're watching live, feel free to ask. So Dev with Sedan says, could you, for example, turn that 3D racer game that we talked about earlier, could you turn that into a tunnel, for example?
