AI PBR Texturing for 3D Models

Every image-to-3D and text-to-3D generation on Trify3D ships with the full PBR texture set baked in — albedo, normal, roughness, metallic. Standalone retexture of an existing mesh is in progress.

What is AI texturing here?

AI texturing means the model arrives with materials already applied — you are not UV-unwrapping and hand-painting in a separate tool. When you run image-to-3D or text-to-3D, the engine generates the mesh and the PBR texture maps in one pass, and they travel together through export. This is texturing as a property of generation, not a separate workflow you pay for on top.

The four PBR maps you get

Albedo

Base color of the surface, with no lighting baked in.

Normal

Fine surface detail — scratches, grain, panel gaps — without extra polygons.

Roughness

How matte or glossy a surface appears under light.

Metallic

Whether a surface reads as metal or non-metal in a PBR shader.

Retexture an existing mesh — coming soon

Standalone retexture — uploading a mesh you already have and generating new textures for it — is in progress and not in the studio yet. Today the path is to generate fresh from an image or prompt, which produces mesh and textures together. When retexture ships as its own flow, this page will document it. We are calling this out plainly rather than implying it works today.

For background on the PBR (physically based rendering) map convention Trify3D follows, see the Khronos PBR reference and the Microsoft PBR documentation.

Related: if you want to imprint a flat image onto an existing 3D model (emboss, engrave, color project, lithophane), that is a separate operation from AI texturing — the guide covers four free methods.

The UV-and-paint tax

Hand-texturing is a separate job after modeling

  • UV-unwrapping a generated mesh so you can paint on it — a fiddly step that adds nothing visible.
  • Hand-painting PBR maps in Substance when the engine already knows what the material should look like.
  • Round-tripping the mesh through a texturing tool loses the geometry-texture alignment the engine produced.
  • Paying for a separate texturing subscription on top of your 3D generation tool.

Textures arrive with the mesh, not after

Image-to-3D and text-to-3D produce the full 4-map PBR set (albedo, normal, roughness, metallic) in the same pass as the geometry, across all three engines (Tripo3D ~48s, Meshy ~76s, Rodin ~90s). No UV unwrap, no separate paint pass, no second tool. The maps travel with the mesh through GLB export at up to 4K resolution.

The PBR set

Four maps, one generation

Every image-to-3D and text-to-3D output ships with the full PBR texture set. These are the four maps and what each one does.

Albedo map — flat base color of a 3D model

Albedo

Base color with no lighting baked in.

Normal map — surface detail of a 3D model

Normal

Fine surface detail without extra polygons.

Roughness

Matte or glossy under light.

How it works

Texturing as a property of generation

You are not UV-unwrapping and hand-painting in a separate tool. The mesh and the PBR maps arrive together.

Generate from image or text

Use image-to-3D or text-to-3D. Textures are generated with the mesh by default — no separate step.
Image or text prompt producing a textured 3D mesh

Guide the material with a prompt

On engines that expose a texture prompt, name the material explicitly — brushed metal, weathered stone, glossy plastic. The engine factors it into both mesh and texture.
Texture prompt field naming a specific material

Export GLB with textures baked in

GLB carries all four PBR maps in one file. For glTF, OBJ, or STL trade-offs see the export formats reference.

Who needs this

Three workflows that benefit most

Generated PBR textures pay off where the material matters as much as the mesh.

🎮

Game artists

Skip the UV-and-paint pass on background props. GLB lands in the engine with materials already applied.

🖼️

Product visualizers

Generated meshes need realistic materials for render. PBR maps get you 80% of the way without Substance.

🧪

Prototypers

Get a textured mesh into a viewer in one export, instead of bouncing between modeling and texturing tools.

🎨

Concept-to-3D

Concept art carries material cues the engine reads. Name the material in the prompt and it factors into both mesh and texture.

From the pipeline

What changes when textures are free

"Background props used to need a texturing pass even when the mesh was fine. Now the GLB drops into Unity with PBR already on it. We only hand-paint hero assets."
Game artist
Indie studio
"The texture prompt is the underrated feature. Naming brushed metal or weathered stone pushes both the mesh and the texture in the right direction. Worth using."
3D generalist
Product visualization
"I tried retexturing an existing mesh and hit the 'coming soon' wall. Fair enough — they said it plainly. Generating fresh got me textures immediately instead."

FAQ

AI texturing questions, answered

Does Trify3D generate PBR textures with the 3D model?

Yes. Every image-to-3D and text-to-3D generation produces a mesh with PBR textures applied — albedo, normal, roughness, and metallic maps travel with the model. You do not run a separate texturing step after generation.

Can I retexture a mesh I already have?

Standalone retexture — uploading an existing mesh and generating new textures for it — is in progress and not yet in the studio. Today the path is to generate fresh from an image or prompt, which produces both mesh and textures together. We will surface retexture as its own flow when it ships.

Which texture maps do I get?

The full PBR set: 4 maps — albedo (base color), normal (surface detail), roughness (how matte or glossy), and metallic (whether a surface reads as metal). These are the four maps most game shaders and render engines expect, generated at up to 4K resolution depending on the engine.

Can I guide the texture with a prompt?

On supported engines, yes. A texture prompt lets you push the material direction — for example naming brushed metal or weathered stone — and the engine factors it into the generated textures. Not every engine exposes this; the studio shows the field where it applies.

What format carries the textures on export?

GLB and glTF carry the PBR textures baked in. OBJ and STL are geometry-only by spec and drop the texture data. For any workflow that needs the materials, export GLB — see the export formats reference for the full breakdown.

How is AI texturing different from imprinting an image onto a model?

AI texturing generates a full PBR material from the prompt or photo during mesh generation — albedo, normal, roughness, metallic in one pass. Imprinting an image is a separate operation that bakes a flat picture onto an existing surface (emboss, engrave, color project, or lithophane). For the imprint workflow across free tools, see the image-to-3D imprint guide.
