Error message on TearableClothRenderer during tearing the cloth - cycle6 - 24-01-2022
So it happens on a particular cloth I've created out of a skirt model.
The cloth doesn't tear appropriately, and it throws an ArgumentOutOfRangeException.
Tearing works fine on other meshes I've tried tho.
The error message shows as follows.
"ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Please advice how should I debug this, thx.

Hi there,
Since this only happens with a specific mesh, chances are your mesh is non-manifold. Non-manifoldness is not supported as described in the manual:
http://obi.virtualmethodstudio.com/manual/6.3/clothsetup.html
Make sure there are no malformations in your mesh. Most modeling packages have functions to automatically detect and fix non-manifold structures (edges shared by more than 2 edges, isolated vertices, zero-area faces, etc).
If you're unsure about this, you can send your mesh to support(at)virtualmethodstudio.com for me to take a look at it.
kind regards,
