Like for region and mesh attachments, Spine uses the attachment name for the Image path
is not specified. In your case the attachment name is ``FT sparks/spark 2/01. That means the images the sequence attachment will look for will be:
[code]
FT sparks/spark 2/0101
FT sparks/spark 2/0102
FT sparks/spark 2/0103
FT sparks/spark 2/0104
etc
[/code]
I can't see what your image files are named on disk, but I'm guessing you should name your attachment
FT sparks/spark 2/` and then it will look for these images:
FT sparks/spark 2/01
FT sparks/spark 2/02
FT sparks/spark 2/03
FT sparks/spark 2/04
etc
