如何获取游戏内角色模型（仅用于动画和图像渲染，不得用于商业用途，不得重新分发）？
The game models can't be distributed like that. You'll have to modify the game files to do that, which is extremely complicated. However, you can get the models in the full version of the game at the bottom of the purchase page. The models are from the Unreal Engine version and are in .blend format.
