Help I have some questions about the fabric

[tecnnt]

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.

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

Whether it can be understood as: whether the model itself is a perfect manifold geometry. Obi supports as long as the geometry can be flattened into a piece of cloth?

I have uploaded an attachment. I think this model should not satisfy Manifold Objects. Because I did a grid split of orders and edges. However, it can be simulated normally in OBI. So I'm conflicted about these two concepts
