You can create the sprite collection in any directory. Why do you rename the sprite collection inside the data folder? You can have more than one resources folder.
SpriteColl2 (sprite collection)
SpriteColl2 Data
SpriteColl2 (sprite collection data)
Atlas, etc.
TO
SpriteColl2 (sprite collection)
SpriteColl2 Data
Atlas, etc.
Resources
SpriteColl2 (sprite collection data)
Loading like that should work, as long as the object is in resources.
Is this how its set up?
