Scaling HDR image

Hi All,

I’ve followed a bit of an obscure tutorial on putting a hdr background into my level, however I can’t scale the image for some reason and it looks like the image is zoomed in too much.

How can i scale the image so it looks correct proportionally?

I think this BP which is a bodge of the M_sky_panning clouds material may be to blame, any ideas?

I only need to move the image down slightly, any ideas?
