If someone can tell me how do thank you .
I think that you need to create a transparent image for the marker, sized to the dimensions of the pieces that you wish to overlay. With a stack this might mean using an over-sized marker.
I have not created a completely transparent marker myself but I have got one that is part transparent / part not. My example outlines the edge of the hex and has a centre dot, so not exactly what you want. However, I can confirm that the transparent part of the marker does mask the underlying pieces (e.g. right-click gives a menu for the marker). The marker in this case is non-movable and does not stack either.
Have you tried a fully transparent image?
If you arenβt sure how to create one, just open a copy of the image file for of one of the stacked pieces, in a graphics program. Select the entire image and cut it. This should give you a transparent image that is the same size as the piece. Save this file and use it as the image for your marker. You can experiment from there.
Thank you for your long explanations and i see but not easy special.
Not yet. but i will
