Free AI 3D texturing tools in 2026: an honest guide

Updated 2026-10-17 · 6 min read

"Free" means different things for AI texturing. Some tools are free because they run on your graphics card. Some give a monthly allowance of cloud credits. Some are free to try but put limits on what you can do with the results. This guide sorts them out, so you can pick one that fits your computer, your budget and how you plan to use the textures.

We make one of these tools, the AI 3D Texturing Studio, so we have tried to be fair: every fact about another tool comes from that tool’s own page, linked at the bottom. Prices and plans change often, so check before you rely on them.

Try it on your own model

Upload a GLB, OBJ, FBX, STL or PLY file (or pick a sample), describe the look, and let AI paint it from every side.

Open the AI 3D Texturing Studio

What to look for first

Before comparing names, answer four questions:

Does it texture a model you upload? Many "AI texture" tools only make flat, tileable materials or only texture models they generated themselves.
Where does the AI run? Local tools need a strong graphics card (often NVIDIA). Cloud and browser tools work on any laptop but use credits.
What licence do free results get? Some free plans put outputs under a public licence or restrict commercial use.
What do you get out? A textured GLB/FBX/OBJ, just a texture image, or PBR maps too.

ArmorPaint	Desktop and mobile; AI runs locally	Source code is open	Ready-made desktop build is a paid download; 6 GB VRAM recommended for AI
Meshy	Browser (cloud)	Free plan with 100 credits a month	Free-plan outputs are licensed CC BY 4.0 (attribution required)

Browser tools (no GPU needed)

The3DAI AI 3D Texturing Studio

Our studio paints models you upload: GLB, GLTF, OBJ, FBX, STL or PLY up to 60 MB, or one of four samples. You describe the look, pick a style if you like, and Auto texture paints the front, right, back and left views. Auto can also paint 6 or 8 views to reach the top, the underside and other hidden sides. You can turn the model and paint any extra view, fill only the grey unpainted spots, repaint one brushed part with the Select region brush, blend seams with the free Heal brush or touch up by hand with the free Paint brush, compare with the before view, and undo. Your own UVs are kept by default; models without UVs get new UVs automatically. A PBR maps box makes normal, roughness, metal and ambient-occlusion maps from the painted colour, free and in your browser. You download a textured GLB (it carries the PBR maps when you made them) or the texture PNG.

Honest limits: AI painting is not unlimited free. Each view uses 2 credits, and an Auto run uses 8, 12 or 16 for 4, 6 or 8 views; new accounts get 60 free credits. The AI paints the colour (base colour) map only. The normal, roughness, metal and AO maps are worked out from that colour and the mesh, so they are a quick starting point, not hand-tuned material maps, and the optional Remove lighting step only evens out baked shadows roughly.

Try it without installing anything

Open a sample in your browser and press Auto texture.

Meshy

Meshy is a cloud 3D AI platform. Its pricing page lists a free plan with 100 credits a month and lists AI texturing among the features. The important catch for game developers and sellers: the pricing page says free-plan outputs are licensed CC BY 4.0, which allows commercial use only with attribution, while paid plans change that. Read the licence before you put a free-plan texture in a commercial product.

3D AI Studio Texture Painter

A browser-based 3D painting app. Its Texture Painter documentation says hand painting, layers, decals with your own images, import and exports are free with a free account, while AI painting in the Texture Painter requires a paid plan. That makes the Texture Painter a free hand-painting tool with paid AI on top. (3D AI Studio also has a separate Texture AI generator; this section is about the Texture Painter.)

Local tools (free if you have the GPU)

Local tools have no per-use cost and keep your files on your machine. In exchange, you install and update the software and its AI models yourself, and you need a graphics card with enough memory.

Dream Textures (Blender add-on)

Dream Textures brings Stable Diffusion into Blender. Its GitHub page describes texture projection for whole models and scenes using depth-to-image, says it was tested on CUDA (NVIDIA) and Apple Silicon GPUs, and recommends more than 4 GB of VRAM. It is GPL-3.0 licensed. Good if you already work in Blender and have the hardware.

StableProjectorz

A free desktop app for texturing 3D models with Stable Diffusion by projecting generated images onto the model, keeping the original UVs, with multi-view projection and brush blending. Its site offers a Windows download and lists an NVIDIA GTX 1080 or newer and at least 12 GB of RAM (AMD needs extra setup). Powerful, but it is a desktop setup, not a quick browser tool.

ArmorPaint

A stand-alone PBR texture painter for Windows, Linux, macOS, iOS and Android. Its site lists local neural features such as textures from text prompts and PBR maps from a photo, with a GPU of 6 GB or more recommended. The project is open source; the ready-made desktop build is a paid download (the price is on its download page).

Blender Texture Paint

Not AI, but worth knowing: Blender is free and open source and has a Texture Paint mode for painting directly on a model. Many people use it to touch up AI textures (fix a seam, paint a logo) after the AI pass.

Which one should you use?

If you…	Start with
have a normal laptop and want a result in minutes	A browser tool such as our studio
have an NVIDIA GPU and like tinkering	StableProjectorz or Dream Textures
live in Blender already	Dream Textures for AI, Texture Paint for touch-ups
need full PBR painting control	ArmorPaint, or a paid painter like Substance 3D Painter
plan to sell or ship the asset	Any tool, but read the output licence on your plan first
want to colour a 3D print	A tool that exports GLB/OBJ with a texture; see adding colour to an STL

Tips for getting good results from any tool

Prepare the mesh. Clean geometry and sensible UVs help every tool. See UV unwrapping explained.
Write surface prompts. Materials, colours and wear, not scenes and lighting. Our prompt guide has examples.
Expect a touch-up pass. Hidden areas, seams and small text usually need attention whatever tool you use.
Check the licence on your plan before using results commercially.

Questions

Is there a completely free AI tool to texture a 3D model?

Yes, if you have a capable graphics card: local tools such as Dream Textures and StableProjectorz cost nothing to use. Browser tools work on any computer but use credits after a free allowance.

Can I use free AI textures commercially?

It depends on the tool and plan. Some free plans put outputs under a public licence that requires attribution. Always read the licence section of the pricing or terms page.

Do these tools make PBR maps?

Some do, some only make the colour map. In our studio the AI paints the colour map, and the free PBR maps box then makes normal, roughness, metal and AO maps from it in your browser. See PBR maps explained for what each map does.

Ready to texture something?

Upload a GLB, OBJ, FBX, STL or PLY file (or pick a sample), describe the look, and let AI paint it from every side.
