Introduction of Tencent InstantMesh

The world of 3D rendering has witnessed a huge development with Tencent‘s latest 3D rendering AI model, InstantMesh. This innovative tool has the capability to generate high-quality 3D renders from static images within a matter of seconds. With its Large Reconstruction Model (LRM) architecture, InstantMesh offers a large upgrade over Tencent’s previous framework, Instant3D.

Now we will explore the features and functionalities of Tencent InstantMesh, delve into its underlying technology, and discuss its potential impact on the field of 3D rendering. We will also examine the benchmarks and compare InstantMesh with other existing models. So let’s dive in and discover how Tencent is changing 3D rendering with InstantMesh.

The Power of InstantMesh

Tencent InstantMesh is an AI model designed to transform static photos into immersive 3D renders. With its advanced algorithms and cutting-edge architecture, InstantMesh can generate highly detailed and realistic 3D objects in a matter of seconds. Unlike traditional approaches that require complex manual modeling and rendering processes, InstantMesh automates the entire workflow, making it accessible to a wider range of users.

One of the key strengths of InstantMesh lies in its ability to solve the “Janus problem” in 3D rendering. The Janus problem refers to the challenge of creating cohesive 3D objects from different perspectives. Often, existing models generate multiple canonical views of the object instead of a cohesive 3D representation. InstantMesh addresses this issue by leveraging a novel view generator fine-tuned from Stable Diffusion, ensuring a more accurate and comprehensive 3D rendering.

The Technology Behind InstantMesh

InstantMesh combines two distinct architectures to achieve its remarkable 3D rendering capabilities. The first is a multiview diffusion model, which processes the input image and generates additional dimensions that are not visible in the original image. This step helps to capture intricate details and enhance the overall quality of the 3D render.

The second architecture is the Large Reconstruction Model (LRM). This model constructs an orbital view object that can be experienced in a 3D environment. By leveraging the strengths of both architectures, InstantMesh is able to create highly detailed and visually appealing 3D renders.

To ensure the efficiency and accuracy of the rendering process, InstantMesh integrates a differentiable iso-surface extraction module called FlexiCubes. This module allows for efficient mesh surface extraction and enables the application of geometric supervisions such as depths and normals directly on the mesh representation. As a result, InstantMesh achieves smoother mesh outputs and enhanced geometry and texture modeling.

Benchmarking InstantMesh

Tencent has conducted benchmark tests to evaluate the performance of InstantMesh compared to other existing models. In the benchmarks, InstantMesh outperformed Stability AI’s Stable Video 3D (SV3D) on Google Scanned Objects (GSO) and OmniObject3D (Omni3D) orbit views. While SV3D performed better in certain parameters related to output resolution in the Omni3D benchmark, Tencent emphasizes that perceptual quality is more important than faithfulness. InstantMesh aims to generate “true novel views” that are unknown and offer multiple possibilities based on a single reference image.

The Availability of InstantMesh

Tencent has made InstantMesh open source, allowing developers to explore its capabilities and contribute to its development. The AI model is available on Hugging Face, a platform that provides access to various AI models. Additionally, Tencent has provided a preview app for enthusiasts to test out InstantMesh and generate and export 3D renders. This accessibility reflects Tencent’s commitment to empowering the wider community and fostering advancements in 3D generative AI.


Tencent InstantMesh represents a great leap forward in the field of 3D rendering. With its ability to generate high-quality 3D renders from static images within seconds, InstantMesh opens up new possibilities for various industries, including virtual reality, industrial design, gaming, and animation.

By combining a multiview diffusion model with a sparse-view reconstruction model based on the LRM architecture, InstantMesh delivers superior rendering quality and scalability. Its integration of the FlexiCubes module enables efficient mesh surface extraction and enhances the training efficiency and overall performance of the model.

With InstantMesh now available as an open-source AI model, developers and content creators have the opportunity to explore its capabilities and contribute to its further development. As the field of 3D generative AI continues to evolve, Tencent’s InstantMesh is poised to make substantial contributions and drive innovation in the industry.
