In the folder for this chapter, open the resources folder and look for 3 files:
BobbleMarine-Head.fbx
BobbleMarine-Body.fbx
Bobble Wars Marine texture.psd
Drag these three files into the Models folder.
Select the Models folder and you’ll see that you have a bunch of new files. Unity imported and configured the models for you and created a folder named Materials.
I selected the Models folder after dragging the mentioned files. The folder ‘Materials’ was not created by Unity . Any ideas?
That sounds like a bug somewhere. I suggest deleting those files and try reimporting them. Also check other folders to make sure that the folder wasn’t imported into another location.
