The embossed object is not above the original object.

how to set so that it is automatically in the same position as the initial object, because too long to move pixel by pixel with the cursor "Offset Y"?

Works okay for me.
Did you try to reset (reinitialiser) and select the aux input (Entrée Aux) again?

After reset,it's the same.

Do you have a selection active?
This is what I come up with when there is a selection active.
Go to selection/ none ... and it works … at least for me.

no selection and just 2 layers

The offset is because the layer (or a selection)used as the bump map is a different size to the layer that is bump mapped.

example - two layers the X for the bump map smaller than the canvas



Apply a bump map and the X is set top-left-corner (offset X / Y = 0)



To keep it in position:

Either apply an offset (which you do not want to do )

or more usually resize the bump map layer to the same size as the bumped layer.

Go to Layer > Layer to image size and apply it in both layers (the bumpmap layer and the layer receiving the bumpmap).
This should fix the problem; As rich2005 said, the offset is caused because the filters take input from the individual layers and not the whole image.

rich2005 and Dionisio

that's it
