The Tencent Hunyuan team officially announced the open-source Hunyuan-GameCraft, a highly dynamic interactive game video generation framework based on HunyuanVideo. It can generate playable and physically realistic gameplay videos from a single scene image and user action signals, supporting first-person or third-person perspectives, providing creators and developers with a new "director-style" way of making games.
1. Core Advantages
1. High Dynamics
Hunyuan-GameCraft uniformly maps standard keyboard inputs to a continuous action space, achieving high-precision control of speed and angle. This approach not only explores complex trajectories and breaks through the problems of stiff and limited movements of traditional models, but also generates dynamic environmental content, such as flowing clouds, rain and snow effects, and water flow.
2. Long-term consistency
Thehybrid historical condition mechanism is used to retain the original scene information after large-scale motion, ensuring the consistency and immersion of the video.
3. Significantly reduce costs
Noneed for expensive modeling and rendering, use PCM distillation technology to compress inference steps, increase generation speed and reduce costs. The quantized 13B model can run on consumer-grade graphics cards like the RTX 4090.
2. Application Scenarios
1. Game Prototyping
Developers can quickly generate interactive video prototypes to verify gameplay, scene dynamics, and physical interaction logic.
2. Film and television and virtual production
Film and short video creators can generate dynamic shots by controlling movements, reducing post-rendering costs.
3. Education and scientific research
can be used in physical simulation, motion trajectory research, immersive education content generation and other fields.

Frequently Asked Questions (Q&A)
Q: Hunyuan-GameCraft Do you need a high-end graphics card to run?
A: Officially, the quantified 13B model will run on consumer graphics cards like the RTX 4090.
Q: What are the advantages of this compared to traditional 3D modeling engines?
A: No need for complex modeling and rendering processes, fast generation speed, and direct video generation based on images and operation signals.
Q: Does multiplayer interaction support?
A: At present, the official documentation mainly shows the generation of single-user interactive videos, and the multiplayer mode needs to pay attention to subsequent version updates.
