**contrafibbularities**: Thank you. Now you can see the results of your pipe joining tutorial!

The first attempt using Realflow for the 'soldered' joint at the rear of the engine assembly, turned out a bit blobby. The 'solder' has since been reworked and all the engine assembly UV mapped using Bodypaint. With most of the pipes properly joined, the number of texture seams have been kept as low as possible.

Once I was happy with the UV mapping, Ambient Occlusion was baked using the settings shown. This AO is used as a mask for a 'dirt' in my paint software. Much greater control using AO this way.
