One prop, two engines
The same generated helmet baked for Unity at 10,000 triangles, then for Roblox at 4,000 triangles with 1024-pixel maps. Switching re-bakes from the full-detail original and uses no credits.

AI Roblox model generator.
Props that fit Roblox's limits.
Describe a prop or attach a picture of one. Mixos AI generates it, sizes it in studs, bakes it to Roblox's triangle and texture limits and writes a file Roblox Studio imports. Ask for lower poly when your experience has lots of players.
- Editable scene
- Browser workspace
- Manual editing in Studio
Mixos AI is available in this build. Conversational tools require paid access or purchased credits.
MADE IN MIXOS01 / HOW IT WORKS
From an idea to Roblox Studio.
Mixos AI handles the size, the triangle count and the textures. You place the prop in your experience.
- 01
Describe it in studs
Name the prop and its size in studs, or attach a picture of it. One stud is about 0.28 m, and mixos AI converts for you.
- 02
Get a Roblox-ready mesh
By default the model is baked to 4,000 triangles and 1024-pixel maps, the same triangle limit as a UGC accessory. Ask for lower poly, 1,500 triangles, for busy servers, or for more detail on a showpiece.
- 03
Import into Roblox Studio
Export the GLB and open it with Roblox Studio's 3D Importer. Check the size, insert it as a MeshPart and set its collision fidelity to Hull or Box.

Made for how Roblox draws a prop.
Within Roblox's limits
A MeshPart can carry up to 20,000 triangles, and Roblox scales textures above 1024 pixels down. Mixos AI bakes under those limits and says whether the prop also fits the 4,000-triangle limit for UGC accessories.
One clean mesh
Roblox works out collision and level of detail itself, so the file holds one mesh with its baked maps. No extra collider mesh turns up in your experience as a visible part.
Sized in studs
Every result gives the prop's height in metres and in studs. Ask for a different size and it rescales without generating again.

Questions about AI roblox model generator
Is Mixos AI available now?
Mixos AI is available in this build. Open the workspace with your Mixos account; conversational tools require paid access or unspent purchased credits. The expanded creation workspace is rolling out in preview builds.
Will the model import into Roblox Studio?
Roblox Studio's 3D Importer reads GLB files. Mixos writes a GLB within Roblox's triangle and texture limits, with the pivot at the bottom. Check the preview's size and textures before you insert it.
Can I make UGC accessories?
Mixos AI tells you when a prop fits the 4,000-triangle limit for UGC accessories. Turning it into a wearable accessory, with attachments and fitting, still happens in Roblox Studio, and publishing UGC goes through Roblox's own review.
How big is a stud?
Roblox treats one stud as about 0.28 m. Give the size in studs or in metres; mixos AI reports both.
What does it cost?
Generating a prop costs 4 to 16 credits depending on quality: 7 for the default and 10 from a picture. Re-baking for fewer triangles and resizing use no credits. Exporting files needs a paid plan. The cost is shown before anything runs.
Can I make several matching props?
Yes. Ask for a pack of up to eight props in one style and colour palette. They can share one texture, which keeps a set of props cheap to draw.
What is free, and what requires a paid plan?
Editing in the released Mixos apps is free with a Mixos account. AI generation consumes credits. Production exports require a paid plan or licence; the free plan includes a 512px watermarked render preview. See Pricing for current allowances. Watching the demonstrations on this page does not spend AI credits.
