Thank you, Nige! I realise now how daft I must appear... It works now but I kept getting intersection errors at low settings so wasn't sure if it;s worth persisting. good to know!. This is where those pop-up texts help boxes would be useful for a quick reference to recommended settings. That would be a good feature for most of the dialog boxes, actually. Short of having a preview with simple sliders... It's been a while since I read the manual... I get confused when the number is a distance and when a ratio/coefficient. Thanks again! Smooth as anything now! I can do 4K.
