Hunyuan 3D v3.1 — Better Textures, Sharper Geometry, 8-View Multiview | TOP 3D AI Learn

Hunyuan 3D just dropped version 3.1 — and yes, it's still completely free with 20 daily credits. That's honestly amazing for what you get.

Important: As of January 7, 2026, version 3.1 is only available on the Chinese version of the platform. The global version hasn't received this update yet.

🎯 What's Improved

The biggest win here is texture accuracy. I really like how textures became more precise in this update. You get:

More accurate textures: Patterns and details are preserved much better
Less blurry areas: Sharper overall texture quality
Fewer artifacts: Cleaner output with less noise
Better faces: Faces are way better now — more accurate and detailed

👤 Faces Are Really Better Now

One area where I noticed a significant improvement is face generation. They're more accurate, have better proportions, and the textures are cleaner.

Hunyuan 3D v3.1 more accurate faces — More accurate face generation

📐 Sharper Geometry

The geometry is also sharper and more detailed. Hard-surface objects especially benefit from this improvement.

🖼️ New: 8-Image Multi-View Support

There's a new 8-image multi-view option. It's optional — you don't have to use all 8 images — but it gives you quite a lot of control over what you want from different angles: top, sides, and so on.

It's good to have a model that supports this level of control. We'll see how many practical use cases emerge — but having the option is definitely a plus.

⚠️ The Smoothing Problem Remains

There's a classic Hunyuan issue that's still present — they tend to make everything smoother, almost like it's waterproof. This is especially problematic with organic shapes.

I attached an example with a small tree — and it looks quite bad. The smoothing just destroys the fine details that organic objects need. Even with 1 million polygons, organic shapes like leaves get smoothed out in a way that doesn't look good.

For non-organic stuff — hard surfaces, objects with clear edges — this update is great. But if you're working with organic models, this smoothing issue is still something to watch out for.

✅ Verdict

Hunyuan 3D v3.1 is a solid improvement. Better textures, better faces, sharper geometry, and a cool new 8-image multi-view feature. And it's still free — 20 daily credits is generous.
