Create 3D Models in Seconds with AI | EASY

Introduction

What if I told you that this 3D chair asset was generated by AI in just seconds? Let me show you how. I went to the Luma AI Discord and found their Genie project. I typed: "high back chair, luxurious leather, burgundy." I was hoping for something reminiscent of the Matrix, and I got something pretty similar on the first try. Luma AI gave me four options, and I liked the first one the most. So I clicked on refine one, and just like that, my chair was ready. I brought it into my game, added some physics, and here it is. I have to say, I love the detail in this model—check out these worn-out edges. It works, gets the job done, and I like the look. Okay, I know this was pretty fast, so let's slow it down and walk you through the steps once again.

Steps to Create 3D Models with Luma AI

Step 1: Join Luma AI Discord

First, you need to go to Luma AI Discord. Make sure you have Discord and go to the Luma AI Discord at Discord.g/LumaAI. I'm also including the link in the video description below, so you can just click there. Once you go to that link, you will see a message that says you've been invited to join Luma AI. Click on accept invite.

Step 2: Write Your Prompt

You will see that their Discord has a Genie prompt guide, which explains in detail what to do. The instructions are honestly very straightforward. You have to go to one of their Genie threads and type /genie and then your description of the 3D model that you want. I typed: "high back chair, luxurious leather, burgundy."

Step 3: Choose Your Model

Once you type in your prompt, Genie goes to work and will soon show you four models to choose from. Notice that underneath the four images you have buttons that read: refine 1, refine 2, refine 3, and refine 4. I liked the first chair the most, so I clicked on refine one. Now Genie went to work on creating a higher resolution version of that model.

Step 4: Claim Your Highest Model

Go to the Genie refine thread and find your model there. This might take several seconds or even minutes, depending on how busy their servers are at the moment. You will see a clear indicator telling you how close they are to finishing it. Once the refined model is finished, you can click on "view in 3D" and "/download".

Step 5: Adjust Textures

The buttons on the right side of the screen allow you to make some adjustments to the texture. Click on the first one if you don't want it to have any reflective properties. A second button makes it so that it emphasizes the lack of roughness—it basically makes it shiny in a way that some plastic objects are shiny. The third button is about the metalness properties; if your object is made of metal or glass, select this one. Finally, the last button has roughness and metalness sliders, and even a tint window where you can change the color of parts of your model.

Step 6: Download Your Model

Click on download. I am on my iPhone, so I decided to simply email it to myself by clicking the share button at the bottom and then choosing mail. Once I downloaded my model, I opened it in Blender to review the topology. My chair had roughly 40,000 faces. The topology is not very clean, but honestly, I didn't expect it to be. It looks like the topology that I'm used to seeing from photogrammetry apps. I was happy to see that the texture was saved as one file that looked nicely packed already, so no complaints here.

From here, it's relatively easy to tinker with the topology and change the model. You can also open the texture in Adobe Substance Painter or some other texturing app. Here, I have more control over the roughness or metalness of individual parts of the object. For example, the worn-out leather part shouldn't be shiny at all, so I'm going to increase roughness on that part. The painted wooden parts could use some gloss, so I'm going to reduce roughness over here. I might give these gold details a metallic look; now that I look at it, I'm not sure if these are supposed to be metal or not. Overall, it's very impressive.

Future Improvements

I would love to see it improved by giving me a chance to iterate on the same model so that I can have a longer conversation with Genie. Once I see the initial model, I would like to simply be able to say: "Make it a little bit taller," "Make the leather texture darker," "Make the gold details silver," and so on. Basically, I would like to be able to iterate in the same way that ChatGPT allows me to, and I have no doubt that these features are coming.

What else would I like from Luma? I would love for this to be an add-on inside Blender. Imagine opening a simple dialog box window inside Blender and simply describing your model there, with the full topology changing in front of your eyes inside the app. Now that I think about it, the idea of typing prompts feels a bit outdated already. Why not use your computer's microphone and have a real conversation with Genie, right? That would be a dream come true for me for sure. And why wouldn't this be possible? We know that Blender add-ons can be capable of a lot. There's a Blender add-on out there already that allows you to type in the geographic coordinates, and it pulls the 3D model data of nearby buildings from Google Maps. I think it's just a matter of time until we see generative AI in the form of a Blender add-on.

FAQ

Q: What is Luma AI Discord?
A: Luma AI Discord is a community platform where users can generate 3D models using AI by providing text prompts to the Genie project.

Q: How do I write a prompt for generating a 3D model?
A: Go to one of the Genie threads in the Luma AI Discord, type /genie followed by your description of the 3D model you want.

Q: How do I claim the model once it's generated?
A: Go to the Genie refine thread and find your refined model. You can view it in 3D and download it.

Q: Can I adjust textures of the model in Luma AI?
A: Yes, you can adjust textures. The platform provides options to tweak reflective properties, roughness, metalness, and even tint parts of your model.

Q: How can I use the model in Blender?
A: Download the model and open it in Blender. From there, you can further tinker with the topology or import it into texturing apps like Adobe Substance Painter for more control.

Q: Will there be a Blender add-on for Luma AI?
A: While not currently available, the idea of having a generative AI add-on for Blender is seen as a possibility in the future. This would allow for model creation directly within Blender.

Q: Why can't I use voice commands to generate models?
A: At the moment, interaction is via text prompts, but the concept of using voice commands is seen as a future improvement that could enhance user experience.
