UV Coordinate offset

yes thats it :smiley:

thank you so much - i set the tiling again to 2, 2 and the image textures to clamp ! then add and substract the uvs to offset the images.
and now the ugly seams finally gone :-D.
i wonder why ceil doesnt work / or floor and the clamp node (min max)
perhaps I’ve overlooked a little thing.

thank you again !!!
