In the field of 3D generation, we often face an “impossible trinity”: speed, quality, and controllability. For most 3D content creators for games and XR, achieving extreme geometric precision often meant long waiting times. To obtain a usable asset, creators had to jump back and forth between multiple software tools.
Today, we are officially launching Hi3D v2.1, a major step forward in AI-powered 3D model generation from images. This is not a simple capability upgrade, but a complete re-engineering of the 3D generative AI workflow.
Below, we detail this update across four dimensions: speed, stability, controllability, and workflow — helping you generate high-quality 3D assets faster than ever, with fewer failed attempts and finer creative control.

Blazing Fast Modeling: High-Precision Models in as Little as 2 Minutes

In the v2.0 era, our standard model already set a high-quality benchmark for the industry. With v2.1, we have deeply optimized the core generation pipeline.

“Turbocharging” Geometry Generation

By introducing a state-of-the-art model distillation acceleration algorithm, we have increased geometry generation speed by over 60% while maintaining a high resolution of 1536³. In typical cases, generation time is now compressed to 3–4 minutes. For objects that occupy less voxel space (e.g., thin, elongated, or simple shapes), it can be as fast as 2 minutes — making fast 3D modeling for prototyping and printing a reality (tested with image enhancement disabled).

“Fast Mode” for Texture Generation

We recognize that not every scenario requires the highest-precision texture baking. Hence, we introduce Fast Texture Mode. In most common scenarios, its visual performance is nearly indistinguishable from the v2.0 standard version, but generation time is reduced by 90%, delivering high-poly textured models in under 2 minutes — ideal for real-time rendering in Unity and Unreal Engine.
Note: For complex hollow structures or heavily occluded areas, we still recommend using the standard version for the best completion results.

Stable Generation: No More Gambling, Reliable Results Every Time

We analyzed a large amount of user feedback on “bad cases.” v2.1 focuses on improving the instability issues caused by low-quality images or real-world scene inputs. With built-in image quality enhancement and geometry repair algorithms, Hi3D is now much more robust — delivering consistent and reliable 3D reconstruction from real-world photos. We want your focus to shift from “will this succeed?” to “how can I use this asset to tell my story.”

Flexible Tuning: Advanced Parameters to Define Your Own Style

Advanced creators want more than “one-click generation.” We want Hi3D to be a finely tunable instrument, not just a recorder. In v2.1, we officially open up the advanced settings panel — giving you fine‑grained control over 3D generation parameters.

1. Delight

A highly practical slider from 0 to 1. You can linearly control how much of the input image’s lighting the AI retains.

• Set to 0: perfectly preserves the original lighting atmosphere (ideal for film rendering).
• Set to 1: completely removes lighting to generate a pure texture map (ideal for 3D printing or material repainting).

2. PBR

One-click activation of physically based rendering materials, directly compatible with game engine pipelines like Unity and Unreal, making metal and roughness responses more realistic.

Additionally, geometry mode, output polygon count, geometry repair, UV unwrapping, texture mode, and other parameters are now fully open to meet the needs of different scenarios.

One-Stop Delivery: A Complete 3D Asset Production Engine

A truly productive tool should not force users to juggle between image editors, 3D generators, mesh repair software, and slicer/print tools. v2.1 represents the full realization of our product vision — an all-in-one 3D content creation platform:

• Native Image Editing: Preprocess input images before generation (e.g., background removal, resolution enhancement) to improve quality from the very beginning.
• Editing & Repair: Generate and you’re done. Decimate, perform boolean operations, or repair edges without exporting to Blender.
  
• One-Click 3D Printing: Directly output formats suitable for 3D printers, creating the shortest path from digital asset to physical object.
  

Pricing & Offers: High-Quality Creation Within Reach

While improving performance, we have significantly lowered the barrier to entry — making affordable high-resolution 3D generation accessible to more creators:

• Price Halved: The 2.1 Fast version (1536 resolution) costs only 25 credits (originally 40 credits)—a 50% price reduction.
• Limited-Time 50% Off Annual Memberships: To celebrate the v2.1 launch, get 50% off annual memberships. This is a one-time opportunity to lock in the lowest cost for the coming year.

Brand Upgrade: From Hitem3D to Hi3D

With this release, we are also simplifying our brand. “Hitem” was originally a variation of “Hi-tech,” carrying our team’s early technical ideals. But as the product matured and we engaged with more creators, we realized that a good tool should not be just a technology label—it should feel like a responsive creative partner.

Hi3D is shorter, more direct, and more like a greeting. We hope that every time you open the platform, you feel not the alienation of a complex tool, but the ease of saying, “Hi, let’s begin.”

Conclusion

Hi3D v2.1 is not just faster — it is more reliable, more open, and forms a complete closed loop. Whether you are a game developer, XR creator, or 3D printing enthusiast, we invite you to experience this next-generation AI 3D asset generation workflow.
