Hi Huub and Stefan. Thanks very much for your reply and suggestions.
Since my last post, Milton has found the time in his busy schedule to make some adjustments with the mappings of the textures in question which has corrected most of the problems. I will use a combination of techniques, similar to what Huub (and others) have suggested to address the remaining issues (only three lines to work on now).
To Milton and to each and every one of you who took the time to respond and offer your suggestions I thank you and salute you.
