i dunno, it looks fine to me
this is not necesarry but u could try using then to make it only one line and loop it for a few times
or maybe u misspelled an overlays name when u were uploading it to your overlays
maybe the overlay is half way throught transparent so you cant see it if opacity 0.5 …
or maybe u forgot to shift and scale the overlay
or you put the int. black - day/night as a background an which u cannot put overlays
