This model is imported through FBX.
The automatic smoothing setting of 0 is useless. It shows that the hard edges are really green and hard edges, and it is useless to press "hard" again.(as shown in Figure 2)
It is not a problem with smoothing groups. It is still the case when all smoothing groups are set to 1.
After UVW expansion, it is not a UVW problem.
This problem can be solved after Tessellate, as shown in Figure 3, but the problem is that I want to know why this happens and how to judge such smooth and wrong objects in a large scene through script (of course, I will study the script first)
Original, FBX imported
Although the hard edge is displayed and I pressed the "hard" button, it is still wrong
After Tessellate, the model is correct

Try to reset normals - Edit Normals modifier, select all and click reset. Imported model from other applications can sometimes have broken or locked normals.
