I created a map using the program Tiled but when I try to import it, I keep getting an error that there is an Missing Texture Asset becuase its trying to access it from the desktop while in unity. the error is:
Unable to open Assets/SuperTiled2Unity/Atlas 1.tsx: Check external application prefrences
note that I am using SuperTiled2Unity and that the asset is in the same folder.
I’m having the same issue, have you found a fix?
Well mine is trying to open it from the correct folder and the file is there. It’s just saying missing texture asset when it’s right there in the folder 
i’m having the same issue, any updates?? 
I believe that .tsx files are able to contain references to graphics files, like .pngs, .gifs, and .jpegs. Did you include your graphic file in the same folder as your .tsx file? Also, all of the file types output by the Tiled editor are human-readable. They are all based on XML file definitions, so you can always just open them in a text editor, to investigate if there are additional file references within them.
