[BUG] Exception when trying to generate blueprint with surface vertices

[JanikH]

Hi,

I just updated to Obi Softbody 6.4 and I'm trying to generate a new blueprint with the "Vertices" mode for surface sampling.
I did a clean package import and regardless of which mesh I select, the following exception always occurs:

IndexOutOfRangeException: Index was outside the bounds of the array.

I'm on Unity 2020.3.28f1.
Let me know if I can help by providing further information.
