Help amount of particles as vertices mesh

[josemendez]

In tutorial of obi cloth(http://obi.virtualmethodstudio.com/tutor...setup.html), there is a sentence "Make sure it has at least the same amount of particles as vertices are in your mesh (the default is 5000)". How do I know that?

There's many ways. Any modeling package should be able to tell you how many vertices your mesh has. Or, Obi itself will tell you upon generating a topology for your mesh: amount of vertices, edges, and faces in your model, along with its area and volume.
