Hi,

Thanks for reporting this! It looks like a bug. In could reproduce it when enabling mesh rendering in the blueprint editor for some meshes, will investigate, fix, and provide a patch asap.

kind regards,

Just fixed this. Attached to this message you will find a patched version of ObiSoftbodySurfaceBlueprint.cs.

Replace your version (found at /Assets/Obi/Scripts/Softbody/Blueprints/ObiSoftbodySurfaceBlueprint.cs) with this one, that shoulder rid of the error message.

Let me know how it goes .
