Help I have some questions about the fabric

[josemendez]

Hello, I checked the forum and the document, and mentioned that the fabric does not support non-manifold mesh. 
Forgive me for my unprofessional, after I read the document you shared, I probably understand the non-manifold mesh.
But what I don't understand is what a 2-manifold is? 

Hi!

A 2-manifold mesh is a mesh that can be unfolded into a continuous, flat 2D surface. Think of a t-shirt: you can cut it at the sides, and then unfold it flat into a table as a single piece of cloth. Basically any real piece of cloth is considered a 2-manifold, non-manifold cloth surfaces could not exist in the real world.

And I see that OBI seems to automatically merge meshes? So Obi will automatically deal with repairing some non-manifold meshes?

No, Obi does not automatically merge meshes or fix non-manifold geometry. All it does is close UV/Normal seams in the mesh, to prevent the simulation from creating gaps at those seams.

let me know if you need further help,

kind regards
