Importing a .tif image file and applying it to a uv dome

Hi

I have created a Dome within Rhino CAD.

Saved as on OBJ to enable me to export it to unfold V9.0.2.

I have unfold and optimised the dome and then successfully loaded my user texture.

my issue now is that when I scale my uv tile, more of the same image appear from the boarder.

I only want one image, to scale and central to the dome.

Any ideas?

best regards

Paul
