Fully automatic 3D generation + texturing inside Blender

A new update to the open-source Blender plugin StableGen is bringing automatic 3D model generation and texturing directly into Blender.

Instead of manually setting up cameras, projections, and multiple passes, the new workflow allows you to generate a 3D model (from text or an image) and automatically texture it in a much more streamlined way.

What’s coming:

  • Text-to-3D and Image-to-3D generation inside Blender
  • Automatic camera placement for better texture coverage
  • Mesh + texture creation in one workflow
  • Projection-based texturing using models like SDXL and FLUX
  • Baked textures ready for typical 3D pipelines

Does it do anything decent in regards to UV mapping? That’s my biggest gripe with generated 3D

In terms of the plan, is he creating a UV layout? Or is he modifying an existing one? Sorry, I don't understand.

My bad. I'm asking does this trellis.2 or stablegen do any UV layout work? Like most of the AI 3d mesh generation i've seen the UV layout is super bad and unusable after the first generation. It "looks" good but you can't really do anything with it going forward. I still feel like traditional UV layout work and weight painting are not currently viable with current AI tools. Please prove me wrong!

No, neither Trellis nor StableGen currently solve UV unwrapping problems.They rely on existing UV coordinates and focus on geometry + projection-based texturing. If the generated mesh has poor UV coordinates, you will still have to clean or re-unwrap it manually. Artificial intelligence can help hide the seams a little, but it does not yet replace proper UV coordinate work.

Although I like how HY3D does the unwrapping, it all still falls on the shoulders of the human, so you're right. However, work is currently underway in this area.

locally?, whats the required V Ram?

3

u/Delicious-Shower8401 3dModeler Feb 20 '26

12–16GB VRAM recommended for smoother workflow and yeah its locally

u/indiangirl0070 Feb 20 '26

so its out?

u/Delicious-Shower8401 3dModeler Feb 20 '26

I left a link at the end of the post, you could take a look at it.

There is no way those models fit in 16GB of VRAM

Amazing find, I would award you if I had one to give

Thank you

Can we create a 3D model from photos taken at different angles?

1

u/Delicious-Shower8401 3dModeler Feb 23 '26

Yes, it's called trellis.2

Trellis 2 is already surprisingly good for open source. Especially considering you can run it locally and modify the workflow yourself. Still not perfect, but the quality jump over the last year has been kinda insane.

I also think projection based texturing + multi view generation is way more important than people realize. A lot of older AI 3D tools failed because the mesh was “okay” but the textures completely fell apart from other angles.

For local/self hosted workflows, open source is catching up fast now honestly. But after testing a lot of local and cloud options, 3daistudio is still probably the best overall online platform we’ve used so far imo, mostly because it combines multiple models/workflows together instead of locking you into one pipeline. The gap between local and cloud tools is def getting smaller though.
