Image to 3D for Blender

Image to 3D for Blender: check the GLB, then import it

  • Turn a photo into a GLB, then import it with File > Import > glTF 2.0.
  • Drop the GLB below first: you get its size in Blender metres, its textures, and whether Blender 5.2 accepts it.
  • Imported models look full of holes until you Merge by Distance. That is the file format, not the mesh.

How to import an image to 3D model into Blender

A generated model arrives as one .glb file: mesh, UVs and textures together. Blender reads it with the glTF 2.0 importer that ships inside every version since 2.80, so the whole import is four moves.

  1. Download the GLB from your Sculptly result. It is free on every generation, with textures included.
  2. File > Import > glTF 2.0 (.glb/.gltf) in Blender, then pick the file. Leave the import options at their defaults for a first look.
  3. Press Numpad . to frame it and Z for Material Preview. Solid shading shows no textures, which is the most common reason a fresh import looks grey.
  4. Check the size in the N panel, Item tab. Generated models have no real-world scale: our three versions of one dog came in at 0.51 m, 0.99 m and 1.84 m tall.

What the importer does on its own, checked in Blender 5.2.2:

The last row comes from the importer's source, not the manual: Blender 5.2.2 manages 22 glTF extensions. One it does not manage is ignored if the file only uses it, and stops the import if the file marks it required.

Six generated GLBs, imported into Blender 5.2

One pet photo and one sign photo, each generated at all three Sculptly settings and imported into Blender 5.2.2 with default options on 25 September 2026. The pictures are Blender renders of the imported files, not our viewer.

Two things stand out. Every file looked broken straight after import, with thousands of open edges, and four of six were completely closed once the split vertices were merged. And High Detail, the setting that keeps faces and lettering best, is the one that still has real open edges afterwards: 43 on the dog, 3 on the sign. Fix those before you print, or leave them if the model is only for rendering.

Headed for a printer rather than a render? Blender's STL export will carry any real holes with it. Run the file through STL file repair first, which caps open holes and tells you what it could not fix.

Questions about image to 3D for Blender

How do I import a GLB into Blender?

File > Import > glTF 2.0 (.glb/.gltf), then pick the file. The importer ships with Blender and is on by default, so there is nothing to install. It converts glTF Y-up to Blender Z-up for you and reads glTF metres as Blender metres, one to one. Textures inside the GLB are packed into the .blend, so the model keeps its colour even if you move the .glb afterwards.

Why is my imported GLB grey in Blender?

Usually because the viewport is in Solid shading, which does not draw image textures. Press Z and choose Material Preview, or switch to Rendered. If it is still grey there, open the Shading workspace and check that an image is linked to Base Color on the Principled BSDF. If the GLB check above says the file has no textures, it will be grey in every mode.

Why does Select Non-Manifold select thousands of edges on an imported GLB?

A GLB splits a vertex wherever its UVs or normals change, so a closed model arrives with open-looking seams. On our Standard Pomeranian that was 41,054 edges on import and 0 after Mesh > Clean Up > Merge by Distance. Run that first; what is still selected afterwards is a real problem.

Should I import GLB or OBJ into Blender?

GLB, unless you only need raw geometry. OBJ carries no PBR textures from a Sculptly export, so an OBJ import arrives untextured and you rebuild the shading by hand. GLB is free on every generation; OBJ is a paid unlock on the same generation.

Which Blender version do I need?

Any Blender from 2.80 onward has the glTF 2.0 importer built in. We tested this page against Blender 5.2.2 LTS, and the extension list the GLB check uses is copied from that version. Older versions manage fewer extensions, so a file that passes here can still fail on a much older Blender.

What does image to 3D for Blender not give me?

No rig, no animation, no UV layout planned for hand painting, and no guarantee of clean quad topology. The High Detail models even arrive with a few real open edges (43 on our dog). Treat the import as a detailed starting mesh that you retopologise, rig or repair in Blender.
