fractures after refinement

[wooni-github]

Thank you for your great work.

I've been attempting to apply your work to my custom 3D model (which was actually created using NeRF). It seems that the model has been refined effectively, but it exhibits strange fractures on its exterior. None of the models included in your dataset had these fractures after refinement. What could be the issue?

It seems that the random initialization of the signed distance function (SDF) occasionally results in meshes with fractures that persist until the FlexiCube refinement process concludes. Interestingly, these fractures weren't evident in the dataset you provided. I'm curious to understand why this disparity exists.
