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 the Matrix look and I got something pretty similar on the first try. Luma AI gave me 4 options. I liked the first one the most so I clicked on Refine 1. And just like that, my chair was ready. I brought it into my game, added some physics, and here it is. I love the detail in this model. Check out these worn out edges.

STEP 1 - Go to Luma AI’s Discord
Make sure that you have discord and go to the Luma AI discord at discord.gg/lumaai . I am 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 pretty straight forward. You have to go to one of the GENIE threads, and type “forward slash GENIE”, and then choose the genie command prompt 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 is going to go to work and will soon show you 4 models to choose from. Notice that underneath the 4 images you have buttons that say

Refine 1, Refine 2, Refine 3, Refine 4. I liked the first chair the most so I clicked on Refine 1. Now Genie went to work on creating a higher resolution version of that model.

STEP 4 - Claim your high res 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 / 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. Second button makes it emphasizes the lack of roughness - it basically makes it shiny in the way that some plastic objects are shiny. The third button is about the me tallness properties - if your object is made of metal or glass, I would select this one. And then finally, the last button Has roughness and metalness sliders. And even a tint window where you can change the color of the 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 in Blender to review the topology. My chair has roughly 40,000 faces. The topology is not very clean but honestly, I didn’t expect it to be. It looks like a topology that I am used to seeing from photogrammetry apps.

I was happy to see that the texture was saved as one file that looked nicely packed already. No complains here.

From here it’s relatively easy to tinker with the topology and change the model if you want to do that.

Overall, it's very impressive. 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 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.
