Assertion failed on expression: 'offset + size <= bufLen'

Hi,

Followed the quick setup guide.  Brought in an Obi Solver into the scene, set a child object with a Skin Mesh Renderer up with the Obi Cloth Component (along with it's additional components all left as default), then clicked initialize.

After hitting play, I get slammed with this error message:

Assertion failed on expression: 'offset + size <= bufLen'

Over and over again.  Everything in the setup was not really modified a part from bringing in the appropriate data for setting up the Game Object.  Has anyone had to deal with this issue and/or know how to deal with it?

I've brought just the Model into a scene and set it up, got the error message when it's simulating.  In our main scene, as soon as the character is to animate through a Timeline, the character freezes up and the child object on the character isn't getting affected by the Obi Cloth.

Thanks,
Cole

Hi,

Nope, this is the first time I've seen such issue. Can you share a bit more about your setup?

- Did you set up the SkinnedMeshRenderer manually? If so, skinning won't work at all. because it will have no bones. This is always automatically set up by Unity when you drag a character into the scene (or any other object making use of skeletal animation for that matter). If the object has animated bones, Unity will add and set up a SkinnedMeshRenderer automatically for you.

- Did you create a topology asset matching the mesh used in the skinned mesh renderer, and fed it to the ObiCloth component?
- How dense is your mesh? Is there a chance you can share it? (to support(at)virtualmethodstudio.com)
