多视图生成3D时报错

[sp1cae]

多视图和主视图都是项目生成的，有时会出现下面的错误： assert cos_angles.mean() < 0, f"The view direction is not correct. cos_angles.mean()={cos_angles.mean()}" AssertionError: The view direction is not correct. cos_angles.mean()=0.062265731394290924

换seed

换seed，这个是因为代码里有一行 assert 检查最后一步前所有面的朝向（你也可以强行删掉这个assert），如果存在一些面是错误的方向，说明这个模型大概率迭代崩掉了

大佬这个assert是来源于哪个代码

I have the same issue, any solution? @wukailu Did you mean to remove the line or control this assertion line if there are some faces that are facing the wrong direction checking the error? I think can add a tolerance of 0.05. Make sense?

# find invalid faces
cos_angles = (faces_normals * view_direction).sum(dim=1)
assert cos_angles.mean() < 0.05, f"The view direction is not correct. cos_angles.mean()={cos_angles.mean()}"
selected_faces = unique_faces[cos_angles < -eps]
