如何避免Hunyuan3D-2生成的模型出现结构扭曲或空洞?

2025-08-28 1.5 K

结构完整性保障方案

针对模型结构问题,可采取以下措施:

  • Input Preprocessing::
    • 图像输入时确保主体占比>60%且背景干净
    • 文字描述应包含”完整的”、”实体”等限定词
  • technical program::
    1. 使用多视图生成模式:Hunyuan3DDiTFlowMatchingPipeline.from_pretrained('tencent/Hunyuan3D-2mv')
    2. 启用形状修复功能:添加use_shape_correction=Trueparameters
    3. commander-in-chief (military)top_k参数调至0.7-0.9范围增强稳定性
  • emergency management:在输出为.glb文件后,使用MeshLab进行空洞填充(Filters → Remeshing → Close Holes)
