Quote - Well the edges of the tiles have to be somewhere :biggrin:

If you want to shift the image horizontally or vertically, you'll have to add an additional constant offset to U_Offset and V_Offset. Try adding .5 to both to shift it half an image. You'll need more nodes.

In matmatic I'd say:

uo = U - P(scale, 0, 0) + .5
vo = V - P(0, scale, 0) + .5

Yes,  I did something similar by converting the P nodes to absolute values.  I guess I was looking for something closer to the way that Vue does this which pins the entire map to the infinite extents of the scene so you would not see any seams when set to a scale of 1.  Anyways, thanks again for the help.
