What is the grey transulcent dot on my textures?

Hi,

This is gonna be a stupid question but what is this grey translucent dot on my textures and how do i move it.

I’m making a procedurally generated game, on the prefabs i downloaded from a website, (the image attached called “Grey Dot”) the grey dot is where the last level piece generated attaches too.

However on my own made textures,( The attached image “Grey Dot 2”) the grey dot is in the middle of the texture meaning level pieces don’t attach correctly. I need to move it but don’t know how.

Thanks

try to move pivot point: select the texture in assets, go to sprite editor and move pivot point from middle to needed place.
