Watertight meshes

[FiscalTax]

I am working with Thuman2.0 dataset and I need to obtain watertight meshes. Many people processed the .obj files with the fast winding number algorithm, but I didn't understand how to apply it. Do you know any libraries, or available codes to easily obtain watertight meshes?

I have the same problem, have you solved it?
