Just wanted to copy the planar mapping incl the surface and change the texture but it would update the original - how can I easy cut the link?
Did you follow the suggestion the yellow note at the top gives you, i.e. did you create a duplicate material?
That should allow you to change the texture image, which would use the same mapping, but leave the original material intact.
@nathanletwory you are a star!!! Thanks worked like a charm.
