Goblin,
Thank you so much for your very fast reply.
I am sooooo...grateful to you because I had absolutely no idea the 'modules' were accessible via the 'boxes' on the edge of the editor, now I know that it was easy to get it all working.
I had been looking in the 'objects' all this time
We will be using your mod soon for an extensive Campaign set on the Australia and later Helvantis maps, can't wait to see what you have done with the SDVs later today.
Very happy indeed, many thanks again
Best regards
SSM Lancaster
