How to improve my mesh effect

[xujiamingtxwd123]

Hi，Thank you very much for open source such a good project。

The effect is still good after I mesh it, but it looks like there is some white content from a distance. I don't know what this is and how I can optimize it.

I have referred to (https://github.com/Anttwo/SuGaR/issues/114) and modified the normal_consistency_factor to 0.3，but there are still some white lines。
