Can you export your project in Unity as a Unity Package and send it to me (sean@seanba.com)? I concede the documentation is light but I was also hoping it wouldn't be required. BTW, what youtube tutorial are you following?
Thanks for the response. I found out what my issue was and fixed it. Basically what the issue was, is that when it's imported into Unity, I have to have the exact same folder organization set up as what is on the desktop. Should have been a no brainer I guess but I kept not seeing it for a while. I like to keep things nice and tidy with my files, So for instance, I had my TileD tilesets seperate from where my map was on my folder layers, and then I had the tilesets images also saved in yet another folder that was further organized into subfolders and so forth. The key important factor was I needed to A) Make sure that wherever I save the TileD maps, that any of the tilesets and images need to be on the same level or within folders derived from the folder the map is in. Then in unity, if folders were used to seperate things, then they need to be made in unity and placed in the same manner so that it can locate it correctly.
The tutorial I used was:
