How to Modify cloth.obj for Cloth Simulation in PBD Material?

[lay1213]

I would like to modify the cloth.obj file to create different shapes and designs for cloth behavior during the simulation. However, I am unsure about the following:

What software or tools can I use to edit or create .obj files that are compatible with this simulation?

Are there any specific requirements or constraints (e.g., mesh resolution, vertex properties) that I should keep in mind for the cloth simulation to behave correctly?

Any advice or guidance on how to effectively edit and integrate cloth.obj into the simulation would be greatly appreciated.

Thank you in advance for your help!
