stress alot! Not hard to understand at all. I just drew the map on paper
and boom it was done in just some minutes, didn't have to check for
empty gaps or anything, the only problem I'm having is the one I said
here, good job.
Edit3: I have fixed the issue, it was Unity's fault for not updating the .blend file while in Scene, I even edited your script to see if there was something missing but turns out it was really Unity's fault. anyway Keep up the good work, this Tool can be very usefull to everyone!
