Unity TileMap - Tile have Offset

Hello, I am having a problem

When I create the tile palette, since I want the tiles to overlap, I use offset (as shown below).
Everything works fine when I draw on scene, but the problem is that I want to get the position of the renderer (the position of the blue square- or offset value), not the position of the cell containing the tile.
Thanks for all your help

You want the position in worldspace? Or relative to what?
I assume you can just calculate the position by adding the offset… ?

The problem is i cant find how to get the offset of each cell.
If tile1 offset (3-0-0), tile2 offset (2.25 - 0 - 0) - so how to get it?
I can use TileMap.GetCellCenterWorld to get pos of Cell in world space, but how to get offset from Cell Center to renderer square.

Let’s go back to what you want to achieve here… you want the tiles to overlap, right? I solve that by making the corresponding sprite (image) a bit larger… I don’t use margins…

Next, why would the offset of tile1 be different than that of tile2?
Is the margin set per tile type? Or depending on the location in the map?
