sad NullReferenceException :( #6

Dear Anatta336,

This packes is so promising! and we actually ot it to work quite fast. But then after one push/pull action in unity-colab the following nullreference exception started showing up (please check below).

Tried reboot and re-instals obviously. But nothing worked. It seems to be an error in the driver decal asset.

Hope that you could help us out easily!

I feel a litlle ashamed.

The day of this post i felt rushed for no good reason and made a simple mistake. I added a mesh-filter component to one of my models. But i didn't link it to an actual mesh - hence the nullreference exception.

We found out a litlle while later that this was in fact the problem.

I assume, happily, that you haven't invested any time into this issue yet.

...

The problem was to simple to speak of.

I hope to have not been to much of a nuissance!

And many, many thanks for a wonderfull package. It will solve technically exactly what we need.
