mesh quality improvement

[dmw1219]

Hi there, I've tried using Magic-Boost to improve the result from InstantMesh, here is the outcome:

The texture quality has improved a lot. But the mesh becomes rougher, and has holes on it. Is there any way to improve mesh quality? ( I'm using threestudio marching cubes to export the mesh)
